Abstract :
The H/sup +/, H/sup -/ linac of the INR meson factory designed for accelerating the 0.5 mA average current beam to energies of up to 600 MeV is being tuned. The results of the tuning of the drift tube linac operating at a frequency of 198.2 MHz with an output proton energy of 100 MeV, followed by the four disk and washer (DAW) cavities operating at a frequency of 991 MHz with an output energy of 160 MeV, are presented. It is shown that the longitudinal parameters of the beam at the output of the first stage of the linac (phase length of bunches of 13 degrees measured with the bunch length monitor and momentum spread of +or-0.76% measured with the magnetic analyzer) are a bit better than designed. Therefore, the beam losses due to longitudinal motion in the down stream part of the linac at the designed current of 50 mA are likely to be negligible.<>
