1 Introduction

Synchrotron Radiation (SR) is emitted by charged particles travelling in curved trajectories at relativistic

speed and has emerged as a highly important tool for basic and applied research in physics chemistry

biology and industry More than 80 SR sources are currently operating across the world and in India two

dedicated synchrotron sources Indus-1 and Indus-2 have been built at the Raja Ramanna Centre for Ad-

vanced Technology Indore Indus-1 is a 450 MeV source with critical wavelength of 61Aring designed cur-

rent of 100 mA and lifetime of 18 hrs This was commissioned and made available for beamline installa-

tion by early 2000 [1] On the other hand Indus-2 is a 25 GeV electron energy source with critical wave-

length of 2 Aring designed beam current of 300 mA and a lifetime of 24 hrs The first light was observed

in December 2005 and presently it has been operating at 25 GeV and 100 mA It can accommodate a to-

tal of 21 Bending Magnet (BM) beamlines and 5 Insertion Device (ID) beamlines out of which six BM

beamlines are operational and seven more BM beamlines are in advanced stage of installation In this

paper we describe in detail the current status of the storage ring the different beamlines and their utiliza-

tion We also discuss about the planned upgradation in the storage ring and the beamlines

The storage ring consists of 8 unit cells each with 45 m Long Straight Section (LSS) and consists of two

225 bending magnets several quadrupole and sextupole magnets Both Indus-1 and Indus-2 are injected

using a common 20 MeV Microtron and a 450-700 MeV Booster synchrotron The RF system required

to replenish the energy lost by the electron beam consists of four cavities to be powered by four stations

excited by 64 kW RF power from klystron sources and the operating frequency of the RF system is

505812 MHz The first light from the storage ring was observed in December 2005 and round the clock

operation was started in February 2010 and operation at 2 GeV and 100 mA beam current was achieved in

March 2010 Since only two of the klystrons were functional Indus-2 operation was restricted to 2 GeV

and 100 mA Due to continuous operation the vacuum in the ring improved to better than 1x 10-9

mbar

and with application of closed orbit distortion correction the beam lifetime has improved from 05 hrs in

March 2010 to 23 hrs in Decemeber 2011 as shown in figure 1Due to the unavailability of klystrons the

RF Systems Division have indigenously developed solid state RF amplifiers of 20 kW and 30 kW power

which have beendeployed for Indus-2 operation With the support of these RF amplifiers Indus-2 opera-

tion have been enhanced to 25 GeV and 100 mA beam current in December 2011[2]

3 Indus-2 beamlines and their utilization

Indus-2 can accommodate 21 BM beamlines and 5 ID beamlines Currently a total of 16 BM beamlines

have been planned and 6 beamlines are operational Two beamlines are nearing commissioning and five

other beamlines are in an advanced stage of installation and expected to be operational by 2013 The In-

dus-2 beamline layout is shown in figure 2 and Table I lists the primary specifications of six operational

beamlines

The Dispersive EXAFS (DEXAFS) beamline was the first to be commissioned and consists of a Rh

coated cylindrical mirror and 460 mm long Si(111) crystal mounted on an elliptical bender which focuses

the lsquopinkrsquo x-ray beam to a spot of 200 m x 400 m on the sample The transmitted intensity represent-

ing the EXAFS spectrum is recorded using an x-ray CCD camera with an energy resolution of 1 eV at

10 keV [3] Many users from universities national research laboratories and institutes have used the

beamline for investigation of a wide variety of problems like determination of structural parameters of

metal-organic Cu complexes at the Cu K-edge[4] Eu3+

assisted structural collapse of GaOOH nanorods

[5] study of local structural changes in ZrO2 due to Nd La Gd doping[6] among others

An Angle Dispersive XRD (ADXRD) beamline has been installed and commissioned and it covers an

energy range of 5 ndash 25 keV and consists of a bendable cylindrical Pt coated Si pre and post mirrors a

Double Crystal Monochromator (DCM) with a pair of Si(311) crystals The beam can be focused to

size of 06 mm x 05 mm using bendable second crystal of DCM and the bendable mirrors The experimen-

tal station consists of a six circle Huber 5020 diffractometer and a MAR 345 Image plate A high pressure

facility for carrying out measurements in Diamond Anvil Cell (DAC) and a liquid He cryostat for mea-

surements over 3 ndash 400 K have been commissioned Several studies have been carried out using this

ADXRD beamline and we discuss results on effect of annealing on the microstructure and magnetic prop-

erties of soft magnetic Fe405Co405Nb7B12 amorphous alloys [7] The samples were isochronically an-

nealed for ~1 hr from 300 to 973 K and XRD pattern recorded using 15 keV X-ray shows broad diffraction

pattern characteristic of amorphous phase which transforms to nano crystalline pattern For temperature gt

450oC the sample consists of and -(Fe-Co) nanocrystalline phases dispersed in remaining amorphous

matrix Further anomalous XRD at Fe K-edge (7112 keV) has been used to distinguish between the or-

dered ferromagnetic -(Fe-Co) alloy from the disordered -(Fe-Co) alloy The presence of the (100)

superlattice reflection suggests the formation of atomically ordered -(Fe-Co) nano crystalline phase

The Energy Dispersive XRD (EDXRD) accepts the full white synchrotron beam ranging from 5 to 40 keV

at 25 GeV and is primarily meant for high pressure XRD measurements in Diamond Anvil Cell It is

equipped with a Ruby fluorescence setup for pressure calibration The spot size can be varied from 8 mm x

8 mm to 100 m x 100 m and the XRD pattern is recorded with a HP Ge detector with an overall energy

resolution of ~100 It has been used to carry out high pressure measurements on several compounds upto

25 GPa grazing incidence diffraction from Co thin film deposited on CoO with q vector in and perpendi-

cular to the thin film plane [8] and in-plane diffraction study of melting in Cd-arachidate LB thin films

The microprobe X-Ray Fluorescence (-XRF) beamline covers an energy range of 5-20 keV and the X-ray

beam can be focused to a spot size of 5 x 75 m using a KB mirror allowing recording of selected area

element-specific fluorescent image from spatially in-homogeneous sample It can also be used in the

macro mode for conventional XRF sample analysis and also in total reflection XRF (TXRF) mode for

ultrasensitive detection [9] This beamline has been used to calibrate detector for the Indian Lunar mission

ldquoChandrayan-1rdquo using lunar stimulant sample JSC-1A The beamline in micro-focus scanning mode has

chaeological tile samples collected from the St Augustine church of old Goa (India)

A Soft and Deep X-ray Lithography (SDXRL) beamline to undertake microfabrication research has been

designed installed and commissioned and it covers an energy range of 15 keV to 20 keV which can be

operated in lsquopink beamrsquo mode using two mirrors The x-ray beam is ribbon shaped with size 70 mm (H)

x 10 mm (V)[10] For the fabrication of three dimensional high aspect ratio (few hundred) structures with

minimum feature size of few microns a custom built x-ray scanner is installed as an experimental station

As test experiments the beamline has been used for the fabrication of few micro fluidic devices com-

pound x-ray refractive lenses micro pillars and test patterns with minimum feature size of 15 microm and

aspect ratio of about 40 The structures are fabricated in PMMA and SU8 photo resists

The X-ray Photoelectron Spectroscopy (XPS) beamline consists of a homemade Si(111) DCM an indige-

nous Hemispherical Analyzer (HSA) Test XPS spectrum on Au has been recorded using 5 keV x-ray The

resolution obtained requires considerable improvement and efforts are going on to optimize the resolution

of DCM and HSA

4 Future plans

The Indus-2 performance will be enhanced by replacing all the klystrons with solid state RF amplifiers of

50 kW each application of fast orbit correction and gradual increase of the beam current to 200 mA and

more It is also planned to install 5 Insertion Devices (IDs) Out of these three are undulators for installa-

tion of i) Atomic Molecular and Optical Sciences ii) Angle Integrated Resolved Photoelectron Spectros-

copy and iii) Magnetic Circular Dichroism beamlines one superconducting wavelength shifter for the

EDXRD beamline and one hard x-ray undulator for Protein Crystallography beamline

A Soft and Deep X-ray Lithography (SDXRL) beamline to undertake microfabrication research has been

designed installed and commissioned and it covers an energy range of 15 keV to 20 keV which can be

operated in lsquopink beamrsquo mode using two mirrors The x-ray beam is ribbon shaped with size 70 mm (H)

x 10 mm (V)[10] For the fabrication of three dimensional high aspect ratio (few hundred) structures with

minimum feature size of few microns a custom built x-ray scanner is installed as an experimental station

As test experiments the beamline has been used for the fabrication of few micro fluidic devices com-

pound x-ray refractive lenses micro pillars and test patterns with minimum feature size of 15 microm and

aspect ratio of about 40 The structures are fabricated in PMMA and SU8 photo resists

The X-ray Photoelectron Spectroscopy (XPS) beamline consists of a homemade Si(111) DCM an indige-

nous Hemispherical Analyzer (HSA) Test XPS spectrum on Au has been recorded using 5 keV x-ray The

resolution obtained requires considerable improvement and efforts are going on to optimize the resolution

of DCM and HSA

4 Future plans

The Indus-2 performance will be enhanced by replacing all the klystrons with solid state RF amplifiers of

50 kW each application of fast orbit correction and gradual increase of the beam current to 200 mA and

more It is also planned to install 5 Insertion Devices (IDs) Out of these three are undulators for installa-

The storage ring consists of 8 unit cells each with 45 m Long Straight Section (LSS) and consists of two

225 bending magnets several quadrupole and sextupole magnets Both Indus-1 and Indus-2 are injected

using a common 20 MeV Microtron and a 450-700 MeV Booster synchrotron The RF system required

to replenish the energy lost by the electron beam consists of four cavities to be powered by four stations

excited by 64 kW RF power from klystron sources and the operating frequency of the RF system is

505812 MHz The first light from the storage ring was observed in December 2005 and round the clock

operation was started in February 2010 and operation at 2 GeV and 100 mA beam current was achieved in

March 2010 Since only two of the klystrons were functional Indus-2 operation was restricted to 2 GeV

and 100 mA Due to continuous operation the vacuum in the ring improved to better than 1x 10-9

mbar

and with application of closed orbit distortion correction the beam lifetime has improved from 05 hrs in

March 2010 to 23 hrs in Decemeber 2011 as shown in figure 1Due to the unavailability of klystrons the

RF Systems Division have indigenously developed solid state RF amplifiers of 20 kW and 30 kW power

which have beendeployed for Indus-2 operation With the support of these RF amplifiers Indus-2 opera-

tion have been enhanced to 25 GeV and 100 mA beam current in December 2011[2]

3 Indus-2 beamlines and their utilization

Indus-2 can accommodate 21 BM beamlines and 5 ID beamlines Currently a total of 16 BM beamlines

have been planned and 6 beamlines are operational Two beamlines are nearing commissioning and five

other beamlines are in an advanced stage of installation and expected to be operational by 2013 The In-

dus-2 beamline layout is shown in figure 2 and Table I lists the primary specifications of six operational

beamlines

The Dispersive EXAFS (DEXAFS) beamline was the first to be commissioned and consists of a Rh

coated cylindrical mirror and 460 mm long Si(111) crystal mounted on an elliptical bender which focuses

the lsquopinkrsquo x-ray beam to a spot of 200 m x 400 m on the sample The transmitted intensity represent-

ing the EXAFS spectrum is recorded using an x-ray CCD camera with an energy resolution of 1 eV at

10 keV [3] Many users from universities national research laboratories and institutes have used the

beamline for investigation of a wide variety of problems like determination of structural parameters of

metal-organic Cu complexes at the Cu K-edge[4] Eu3+

assisted structural collapse of GaOOH nanorods

An Angle Dispersive XRD (ADXRD) beamline has been installed and commissioned and it covers an

energy range of 5 ndash 25 keV and consists of a bendable cylindrical Pt coated Si pre and post mirrors a

Double Crystal Monochromator (DCM) with a pair of Si(311) crystals The beam can be focused to

size of 06 mm x 05 mm using bendable second crystal of DCM and the bendable mirrors The experimen-

tal station consists of a six circle Huber 5020 diffractometer and a MAR 345 Image plate A high pressure

facility for carrying out measurements in Diamond Anvil Cell (DAC) and a liquid He cryostat for mea-

surements over 3 ndash 400 K have been commissioned Several studies have been carried out using this

ADXRD beamline and we discuss results on effect of annealing on the microstructure and magnetic prop-

erties of soft magnetic Fe405Co405Nb7B12 amorphous alloys [7] The samples were isochronically an-

nealed for ~1 hr from 300 to 973 K and XRD pattern recorded using 15 keV X-ray shows broad diffraction

pattern characteristic of amorphous phase which transforms to nano crystalline pattern For temperature gt

450oC the sample consists of and -(Fe-Co) nanocrystalline phases dispersed in remaining amorphous

matrix Further anomalous XRD at Fe K-edge (7112 keV) has been used to distinguish between the or-

dered ferromagnetic -(Fe-Co) alloy from the disordered -(Fe-Co) alloy The presence of the (100)

superlattice reflection suggests the formation of atomically ordered -(Fe-Co) nano crystalline phase

The Energy Dispersive XRD (EDXRD) accepts the full white synchrotron beam ranging from 5 to 40 keV

at 25 GeV and is primarily meant for high pressure XRD measurements in Diamond Anvil Cell It is

equipped with a Ruby fluorescence setup for pressure calibration The spot size can be varied from 8 mm x

8 mm to 100 m x 100 m and the XRD pattern is recorded with a HP Ge detector with an overall energy

resolution of ~100 It has been used to carry out high pressure measurements on several compounds upto

25 GPa grazing incidence diffraction from Co thin film deposited on CoO with q vector in and perpendi-

cular to the thin film plane [8] and in-plane diffraction study of melting in Cd-arachidate LB thin films

The microprobe X-Ray Fluorescence (-XRF) beamline covers an energy range of 5-20 keV and the X-ray

beam can be focused to a spot size of 5 x 75 m using a KB mirror allowing recording of selected area

element-specific fluorescent image from spatially in-homogeneous sample It can also be used in the

macro mode for conventional XRF sample analysis and also in total reflection XRF (TXRF) mode for

ultrasensitive detection [9] This beamline has been used to calibrate detector for the Indian Lunar mission

ldquoChandrayan-1rdquo using lunar stimulant sample JSC-1A The beamline in micro-focus scanning mode has
