В качестве триггерного сигнала используется
сформированный сигнал с счётчиков S1-S8 включенных на
совпадение.
Между счётчиками расположены испытываемые детекторы.
Pad RPC1, 2 – две пэдовые МРПК, Strip RPC – стриповая
полноразмерная МРПК и FFD – прототип быстрого
стартового детектора на основе быстрых микроканальных
фотоумножителей. Таким образом, в качестве стартового
детектора могли использоваться как FFD, так и одна из
маленьких МРПК.
Сигналы со всех МРПК снимаются усилителем NINO,
который сигнал усиливает и преобразует в LVDS, ширина
которого зависит от амплитуды входного сигнала. LVDS
сигналы по специальному кабелю поступают на вход
TDC32VL. Сигналы с FFD так же преобразуются в LVDS прямо
в корпусе детектора и считываются в TDC. Все данные
записываются на жёсткий диск управляющего компьютера и
обрабатываются off-line.
