چکیده

The results of the tandem commissioning as initial high voltage tests and beam injection experiments on BINP proton tandem-accelerator are given. The accelerator is intended to be used in facilities generating resonant gamma rays for explosives detection and epithermal neutrons for boron neutron-capture therapy of brain tumors. A magnetically coupled DC voltage multiplier derived from an industrial ELVtype electron accelerator is used as a high voltage source for the accelerator. A dc high-current negative ion source has been developed for injection into the tandem. In the tandem accelerator there is set of nested potential electrodes with openings which form a channel for accelerating the negative hydrogen ion beam and subsequently accelerating the proton beam after stripping in the gas target. The electrodes are connected to a high voltage feedthrough insulator to which required potentials are applied from the high voltage power supply by means of a resistor voltage divider.

A 200 kV Proton Accelerator Dedicated to Low-Energy Beam-Plasma Interaction Experiments

In order to determine the Coulomb logarithm independently from the charge state, we need energy-loss measurement of protons (zeff = 1) with the same velocity as heavier projectiles. Such a measurement has already been performed using 350 keV protons delivered from the tandem accelerator by means of TOF method with a pulsed beam [4]. The terminal voltage of the accelerator was (350-20)/2 = 165 k...
