Possible future evolution will be to obtain a machine to generate higher energy X-ray beams, towards the MeV.

Abstract

The Southern Europe Thomson Backscattering Source for Applied Research (STAR) is a compact hard Xray source designed by INFN, for advanced applied materials-science research. It is funded by Progetto MaTeRiA, a partnership between the University of Calabria and CNISM (Consorzio Nazionale Interuniversitario per le Scienze fisiche della Materia). The machine has been installed at the University of Calabria (UNICAL); the X-ray beam is produced using the Thomson Back-scattering process, where relativistic electron bunches, accelerated by a 60 MeV Linear Accelerator (LINAC), interact with very short photon pulses, produced a by a 30 mJ@5 ps IR (Infrared) Pulsed Laser. The EPICS-based command/control system (ComConS) of the STAR machine has been designed and currently is under commissioning, using state of the art technologies and making extensive use of COTS hardware and software, assuring full control and supervision of the whole machine and all relevant subsystems: Beam diagnostics, Magnets power supplies, RF devices, Laser systems, Vacuum subsystem, Machine Protection System, Personnel Protection System and Trigger and Timing system. A growth potential has been considered since design phase, in order to take into account any future expansions of the control system during the lifecycle of the facility, without impact on the performance. Scalability of systems is also a crucial issue. The current design allows to generate tunable collimated monochromatic X-rays in the range between 10 and 200 keV. Possible future evolution will be to obtain a machine to generate higher energy X-ray beams, towards the MeV. The control system from both SW and HW points of view has to accommodate this need, as well as operating the machine for a long lifecycle.
