First Operation of Proton Induction Linac

A prototype of proton induction linac was developed to study the beam dynamics and the operational characteristics in this type of the accelerator speci-fically in the case of the intense ion beam acceleration. The driver system is composed of three identical unit modules, each of which consists three toroidal cores made of laminated silicon-iron foil of 0.1 mm thick and the driving circuit linked with the cores. The accelerating field of 28 kV/module is obtained typically during a period of 2 - 3 ¿sec. A proton beam of about 200 mA is extracted directly with the field driven inductively by the first module and then accelerated with succeeding two units to give the particles of about 60 keV at the output of the modules. Preliminary results of the measurements of the beam characters are given with the design of the device.
