Pulse power system of linear induction accelerator for fnal neutrino factory

Summary form only given, as follows. Because of the importance of a phase rotation system for the neutrino factory (NF) concept, it was necessary to perform a linear induction accelerator (LIA) feasibility study. The particles to accelerate are muons with the initial energy range from 50 MeV up to 250 MeV. The phase rotation means adjustment of the particle energy by differential acceleration with the goal of the energy-spread reduction. The LIA length must be about 100 m. This results in a quite high for the LIA acceleration rate of more than 1 MV/m. The multiple pulse regime (4 pulses within 2 microseconds) has been requested. Starting pulse length of 150 ns was accepted for this study. As a result, a pulse power system for the neutrino factory LIA has been suggested and developed that allows forming the accelerating voltage pulse which shape meets the NF design requirements. The accelerating voltage on one inductor changes from -75 kV up to +25 kV during the voltage pulse. The results of first approximation in the calculations of the LIA pulse power system with taking in account core power losses are presented in this report. Evaluations of the main parameters were maid for the workable LIA. They gave the following values: one core minimal cross-section is equal to /spl sim/20 cm/sup 3/; one core volume is equal to 5500 cm/sup 3/; the minimal total core volume is equal to /spl sim/11 m/sup 3/ (per 100 in LIA length); the core total weigth is equal to /spl sim/80 ton; average power required from the pulse power system is equal to 4.8 MW.
