[en] Tests have been performed in order to aid detection of components of the hodoscopes and fast electronics for the most demanding conditions: 10⁷ particles per second per counter and a factor of 4 attenuation in the scintillator. The photomultiplier RTC1982 performs very adequately. In order to have an efficiency approximately equal to 99% for counters with a flux of greater than 2x10⁶ particles the necessity of the following components was determined: RG213 cable, clip line, amplifier, updating discriminator with burstguard option
