| WEPPC014 | Performance of the Magnetic System of a 12 MeV UPC Race-Track Microtron | 472 |
|
||
| The performance of the magnetic system of a 12 MeV electron race-track microtron (RTM) which is under construction at the Universitat Politècnica de Catalunya (UPC) is described. The RTM magnetic system consists of two four-pole end magnets with the main field level about 0.8 T, one quadrupole and four beam extraction dipoles. As a source of the magnetic field in these magnets a Sa-Co rare earth permanent magnet material is used. This helps to get a quite compact design of the RTM and allows to place the magnetic systems in a high vacuum environment of the accelerator vacuum chamber. We discuss results of numerical simulations of the tuning of the end magnets by mean of special tuners and describe their engineering design which permits to assemble the magnets and fix the Sa-Co blocks without gluing. Also a method and results of magnetic field distribution measurements and magnet tuning are reported. | ||

Operational experience with 55 MeV RTM * is reported. After RTM commissioning described in * it was installed in specially built bunker with 60-80 cm thick barite concrete walls placed in accelerator hall in order to protect detector equipment from parasitic radiation. New equipment was installed at RTM including new pulsed modulator, high power vacuum window and circulator, new cooling system, additional steering coils. Control system software based on LabView was also modified to make RTM tuning easier. Introduced changes made RTM operation more stable, beam transmission through RTM was improved. After re-commissioning RTM is used for experiments in nuclear physics, in PET isotope production research, in explosive detection experiments etc.

|
||
| Status of 1 MeV 25 kW continuous wave (CW) linear electron accelerator for radiation technologies which is under construction at SINP MSU is described. Driven by 50 kW CW klystron on-axis coupled standing wave accelerating structure was optimized, manufactured and tuned. The results of accelerating structure measurements and tuning are presented. RF system, high voltage, vacuum and control systems of the accelerator are described. New magnetic system forming output beam irradiation field is also described. | ||

Control Systems for Industrial Electron RF Accelerators | |
|
||
| General approach to design of control systems for different purpose electron RF accelerators - for technological processes in industry, sterilization, radiography, etc., constructed at SINP MSU is described. Control system consists from a number of specialized controllers each responsible for separate accelerator system connected via Ethernet with control computer which in turn is connected with control panel computer, modulator, power supplies etc. having own digital interface. Each controller is made of one or several special boards conditioning external analog and discrete signals and universal microcontroller part providing controller operation and network connection. Single board "Blue Shark" computers are used as control computer and control panel computer, both operating with Linux OS. Special Scada system has been developed to provide proper accelerator operation and operator interface with different level of access to accelerator parameters. | ||
