Document Content
The aim of the Selective Production of Exotic Species (SPES) project is to produce accelerated radioactive ion beams, by Isotope Separation OnLine (ISOL) method, for Physics studies at “Laboratori Nazionali di Legnaro” (Istituto Nazionale di Fisica Nucleare (INFN)-Italy). This accelerator complex is scheduled to be built by 2016 for an effective operation in 2017. In the SPES project, the radioactive species are produced in a Target Front-end, and then separated and transported by an electrostatic beam line toward a post accelerator complex. The iThemba LABS management board has recently adopted the SPES Front End (FE) engineering design, in order to assure the ions production in the forthcoming South African radioactive ion-beam (RIB) Facility. This document contains the technical information of the main components of the proposed iThemba LABS Target Front-end, which is an evolution of the SPES Front end, which has been developed and constructed, in the last years, at Laboratori Nazionali di Legnaro (LNL).

GLOBAL PROJECT BREAKDOWN
The project work breakdown structure is reported in Figure 1.
Fig. 1: The Project Work Breakdown Structure
FRONT END TECHNICAL DESCRIPTION
The SPES front-end (see Fig. 2), an evolution of the ISOLDE FE6, is the assembly of all the mechanical devices involved in the production of radioactive beams, and is the main apparatus contained in the SPES irradiation bunker. The main purpose of this apparatus is to connect, once assuring the target chamber handling, the two beam lines, respectively the proton and the radioactive ion-beam (RIB) one.
The main purpose of this apparatus is to connect, once assuring the target chamber handling, the two beam lines, respectively the proton and the radioactive ion-beam (RIB) one. In this apparatus, all components are made of aluminum in order to minimize the material activation as consequence of the huge production of neutrons coming from the production target. Through the proton Front End (FEP) the beam, coming from the cyclotron, is sent into the target chamber unit. Because of nuclear reactions that occur in the production target, the radioactive ions produced, are extracted and sent into the Radioactive Front-End (FER), which constitutes the first part of the radioactive ion-beam (RIB) line.
The Target Front-end is divided into some functional subsystems.
The first one is the target ion-source complex where the ion beam is produced. It consists of a target complex, connected by means a transfer line, the ionizer and the extractor devices.

The target unit is made of a graphite box containing the target disks, windows and dumps (both in graphite) disks, and is contained in a tantalum cylinder, which is resistively heated by passing a high current through it in addition to the heat supplied by the irradiating beam. A small tantalum tube, called transfer tube, connects the target unit to the ion source in order to plug in several kinds of ion sources.
The second subsystem is the Target Chamber, which contain the target and ion complex. The aluminium chamber must be easily removed, for servicing or storage, from both beam lines after the irradiation process. For this reason, the mechanical design of the target chamber strongly takes into account this effect. The target chamber unit is coupled to the proton driver and to the radioactive ion-beam (RIB)’s beam by means of quick connectors.
The third one is the extraction system, which it consists on a movable puller and an electrostatic steerer device.
The last subsystem is the frame (with a fixed and removable part). All components are made of aluminium in order to minimize the material activation as consequence of the huge production of neutrons coming from the production target.
Fig. 2: The SPES/iThemba LABS front end
The TARGET COMPLEX
The target has been designed in order to satisfy some main requirements, such as:
• High number of reactions,
• maximize the isotope release
Accepted by iThemba_Labs
21
• Low power deposition in the materials (both window and target).
A direct target configuration is chosen for the SPES project, consisting of a proton beam (E= 40 MeV) directly impinging on the target. The main problem of this configuration concerns the high power deposition of the incident beam in the production target, mainly due to the electromagnetic interactions.
In order to solve this problem, only the protons with higher fission cross-section are exploited in a thin target, while the outgoing lower energy beam is driven towards a passive dump. In order to optimize the heat dissipation, a good solution is the use of a target constituted by multiple discs. In this way, the cooling of the target is strongly simplified: in fact, due to the void environment, the heat dissipation is fully entrusted to the thermal radiation and this mechanism is directly proportional to the body surface. The use of several thin discs of equal mass increases the total surface and allows for a better cooling.
Fig. 3: The target complex
The target container is a cylindrical Carbon tube 1mm thick with radius 2.5 cm and length 24 cm. The entrance window is a 0.4 mm thick graphite layer of 4 cm diameter. Seven discs of UCx, LaCx or SiC et others, composes the active part of the target, see Figure 3. The discs have a radius of 2 cm and thicknesses of about of 1 mm. The choice of discs material is due to the kind of beam to be produced and accelerated. All different carbide disks can be allocated in the graphite container as shown in Figure 4.

Fig. 4: The carbide discs insert in the graphite box
The target heating system consists of a thin tantalum tube, with an average length of 200 mm, an external diameter and a thickness of 50 and 0.2 mm, respectively. It is welded at its edges to two tantalum wings, which are directly connected to copper clamps, through which an electric current delivered by a 10 kW power supply (maximum current IMAX = 1300 A and maximum potential VMAX = 10 V) heats by Joule effect the Ta tube.
A Tantalum tube (transfer tube) connects the target unit to the ion source complex allowed the possibility to plug in several kinds of ion sources as described in next. The tube is made of tantalum with the external and the internal diameter of 8.8 mm and 8 mm, respectively. It connects the production target and the ion source as represented in figure 5.

The high temperature target system (composed of disks, box and heating system) is located under vacuum inside a water-cooled chamber vacuum and high temperature are essential to enhance the radioactive isotopes extraction as shown in figure 6

THE ION SOURCES
The ion sources dedicated to the production of radioactive ion beams (RIBs) have to be highly efficient, selective (to reduce the isobar contamination) and fast (to limit the decay losses of short-lived isotopes). Ion sources for radioactive beam generation must operate steadily for extended periods at high temperatures (up to 2200°C). The selection of the most appropriate “target - ion source” (TIS) system is of paramount importance since its performance determines the beam intensity, the beam quality, and the number of radioactive beams that can be provided for experimental use. The choice of a specific ion source is primarily dictated by efficiency, and secondarily by its capability of selective ionization. All produced ions are accelerated towards the ion extraction electrode by a potential up to 40 kV.
The three main ionization mechanisms used in the context of radioactive ion-beam (RIB) production are the surface ionization mechanism, the laser ionization mechanism, and the electron impact ionization mechanism. They are associated to the surface ion source, the laser ion source and the plasma ion source, respectively.
The surface ionization mechanism can provide mainly singly charged alkali metal and alkaline earth metal ion beams, and in general is applied to elements with ionization potential lower than 6 eV (in particular for Rb and Cs, but also for Sr and Ba). This technique is quite selective and can allow reaching high values of ionization efficiency, up to 60%.
Metal elements like Ni, Cu, Zn, Ga, Ge, As, Sr, Y, Pd, Ag, Cd, In, Sn, Sb, Te, Ba and La are expected to be ionized by means of the resonant laser ionization mechanism. These elements are characterized by an intermediate value of the first ionization potential, approximately between 6 and 10 eV. The laser ionization technique is surely the most selective one.

24
The electron impact ionization mechanism is indicated for the noble gases (Kr and Xe), the halogens (Br and I), and for Se. All these elements are characterized by an ionization potential higher than 10 eV. This ionization technique is not selective, but can reach quite high ionization efficiency values (up to 40% in the case of Xe).
6.2 The surface ion source (SIS) The SPES surface ion source is a hot-cavity ion source that can be used also during the
photo-ionization process. Its main component is the tubular ionizing cavity (made of Re or Ta) characterized by a length, an external diameter and an internal diameter approximately equal to 35 mm, 5 mm and 3 mm, respectively. It is connected on one side to a stiff support and on the other side to the tantalum transfer line, as represented in Fig. 7. A cylindrical thermal screen contributes to keep the ionizing cavity at high temperature also in proximity of the connection with its support. A thin round plate is located behind the support, to produce an appropriate electrical field between the ion source and the extracting electrode, and to shield the TIS system radiative power. Both the surface ion source and the transfer line are heated by Joule effect using the same electrical circuit.
Fig. 7: The SIS complex allocated in the chamber unit
THE CHAMBER TARGET UNIT
The SPES target chamber unit takes all the engineering principles embodied in the target source modules used in the Holifield Radioactive Ion-Beam Facility (HRIBF) and Isolde projects for remote and safe handling. The attractive feature of this approach is that loose contamination is enclosed in a relatively compact system.
The SPES Target Ion-Source device is housed on a vacuum feed-through situated in a water-cooled base plate and enclosed by an aluminium water-cooled bell jar. The target chamber unit, which weight about 40 kg, is coupled to the proton and to the radioactive ion-beam (RIB) beam lines, by means of quick connectors and valves for isolating the system from the proton beam pipe and Front End (FE), when necessary. The chamber has two handling interfaces placed on the top and in the front of the chamber in order to allow the remote

handling of the target unit after and before the irradiation. A picture of the target unit chamber is shown in Figure 8.
Fig. 8: The SPES target chamber unit
THE COUPLING TABLE
In order to insert/remove easily the target chamber unit to/from the front end, is necessary to build a dedicated device. The coupling table is the key part of the front-end. On it, are mounted structures that must accomplish the following tasks:
• Move the target chamber unit to the front end
• Connect the proton channel to the chamber unit • Allow the hydraulic and electrical connections • Open and close the valves of the chamber.
In the coupling table (se Fig. 9), there are the plugs that are used to transfer water to the chamber cooling and the connections that allow providing the electricity needed to heat the target ion system. The target chamber unit must be positioned into coupling table by an automatic handling device. Once inserted, the chamber is pushed against the flange coupling by a pneumatic piston, which actuates two arms that in their turn push the chamber against the flange in order to permit the electrical connections are plugs and hydraulic ones. It remains to connect the proton beam line with the chamber unit. The connection between the two devices must be carried out with great precision to ensure a high vacuum level.

The coupling of the proton channel is carry out by the thrust performed by a pneumatic cylinder, connected by two shafts, which pushes a bellows hinged on the linear guides against the chamber.
THE EXTRACTION SYSTEM
Once the ionization has taken place, the puller or extraction electrode accelerates the ions. This device consists of a 50mm diameter tube, made of Titanium (Ti). The entrance side of the puller, called head, has conical shape. This head has a 6mm aperture where the accelerated ions pass through. The ion source is held to a high electrical potential, respect to the extractor, by a dedicated high voltage power supply. A maximum electrical potential of 65kV could be applied to the ion source (however, for the off-line version, a maximum of 30kV is set). Additionally, the distance between the ion source and the electrode can be adjusted from 179 to 63mm The extracted beam has a shape and divergence, which are mainly due to the ionization and to the first stage of acceleration. Without the use of focusing lens, the beam keeps its divergence so its spot size grows and decreases its density. In order to drive the beam spot to the desired target it is necessary to steer it and to focalize it.
After the puller, four electrostatic steerers are installed, as reported in Figure 10a and 10b. Four couples of 60mm long cylindrical shaped plates, separated by 55mm, are mounted along

the beam line, each electrode may be supplied by independent +3kV power supplies. This configuration produces uniform electrical fields orthogonal to the beam direction. For each plane, two deflectors are used with opposite polarity to produce a shift of the beam.

The extracting system described above is connected to the coupling table by means an alumina insulator (see Figure 11) that guarantees the platform voltage in order to extract the ion beams.

-‐ Finally, the technicians of iThemba LABS will perform the installation at the iThemba LABS ISOL test stand. A possible visit of INFN personnel is desirable (but not required), in order to verify the proper FE operational system behavior after transporting, reaching the vacuum values obtained in the commissioning acceptance test performed at LNL.
