Scintillation Detector HeadsThe FMB Oxford Scintillation detectors come in two sizes and various configurations that are tailored to meet your individual needs, whether that is an individual detector or an array for a Multi Crystal Analyser.

FMB Oxford offer a range of scintillation crystals and thicknesses. Your individual choice is a balance between count rate and energy resolution. The highest performing crystal in FMB Oxford’s range is Lanthanum Bromide. With a decay time of 16 ns it can register faster photon rates and output a greater light signal per photon than any other crystal types.

IC Plus Ionisation ChambersThe IC Plus ionisation chambers are suitable for use in a number of diffraction and crystallography experiments, including protein crystallography. The IC Plus is available in 4 different electrode lengths to allow optimisation of the detector energy range and fit the physical space constraints of complex end stations.

The shortest electrode lengths give a compact intensity monitor that does not absorb a large fraction of the beam, ideal for protein crystallography experiments where the end station is typically very crowded and scatter should be minimized. The longer electrode lengths yield more accurate measurements at higher energies and might be more suited to certain spectroscopy applications.

High Vacuum QBPMsThe QBPM range of beam position monitors are capable of providing a beam position accuracy of less than 2 microns. QBPM technology is based on an array of 4 large area photodiodes to capture solid angle fluorescence from scintillating foil. The use of different foils allows the QBPM to be used over a range of energies.

The concept is licensed from Argonne National Laboratory and base of design work carried out by R.W.Alkire, G. Rosenbaum and G.Evans.

Beam Position Ionisation ChambersThe BPIC is a split plate ionisation chamber that can be incorporated into a beamline end station in order to measure the position and intensity of the X-ray beam.

A pair of such chambers can be used for X/Y position measurements.

The system is ideal for many applications including optimisation of the second crystal angle in a double crystal monochromator, tuning of mirror incidence angles and controlling the height of end station tables to maximise the flux on a sample.

UHV QBPM AQM0017

Ultra High Vacuum QBPMsUHV QBPMs are designed for monochromatic ID beamlines. They are available in a DN100CF150 or DN160CF200 conflat size and a straddled or non-straddled conflat orientation. For a BM beamline FMB Oxford also offers a QBPM variant, the DBPM, which measures the vertical position of a wide beam.

The UHV QBPM can house up to 2 scintillation foils. A motorised stepper driven foil changer allows the user to switch between the two foils and an out of beam position. Both the diode array and foils can be moved vertically and horizontally within the conflat housing to centre them around the beam without breaking the seal.

All QBPMs come with a 1.5 meter 4-channel BNC signal cable for connection directly to the current amplifier.

Ultra High Vacuum DBPMThe DBPM is designed for monochromatic bending magnet beamlines. The DBPM uses an array of diodes mounted above and below the beam which provides a vertical positional feedback. The unit has a beam aperture of 40 mm (H) x 8 mm (V). The position of the array within the conflat can be moved vertically via a manual micrometer. The foil holder position can be adjusted via a stepper motor.

I3200 Thirty-two channel Digital Electrometer YMCS0024


Ancilliary DevicesBent Crystal Laue Analyser (BCLA)The FMB Oxford BCLA is a versatile, narrow bandpass filter that can enable you to achieve the ultimate performance in a variety of applications, including XRF and XAFS experiments at a synchrotron beamline.

The system, which is compatible with a variety of back-end detectors, rejects undesired x-ray photons (e.g. scattering and fluorescence from other elements in the sample) before they can be detected; drastically improving signal to noise ratio.

The core of the BCLA is a silicon crystal, which is bent into a logarithmic spiral such that X-rays of a selected wavelength are diffracted towards the detector; whilst background radiation is transmitted straight though and blocked by Soller slits. The slit material, crystal shape, and geometry of the BCLA are carefully optimised for a particular working energy range - please refer to the ordering section below to view the suite of options available.

SpecificationsInput beam size ~100 µm in diffracting plane (generally vertical direction)

~1 mm in the perpendicular plane

Bandpass 10 - 100 eV

Input energy ranges 5.3, 6.4, 7.5, 8.4, 9.5, 11.4, 13.6, 16, 18.4, 22 KeV
