Abstract
The use of a silicon photomultiplier (SiPM) has made it possible to produce a compact target composed of 16 active elements capable of measuring ionization losses in each element. The accuracy of a single ionization measurement is sufficient to allow discrimination between single- and three-track signals in 90% of events. A special ΛЭ-80 processor has been developed using the programmable decision lookup table method for trigger signal generation, which is implemented in Altera programmable logic devices. The time it takes for the special processor to produce a trigger signal is 80 ns or less. The possibility of separating reactions with neutral strange particles has been demonstrated using vast experimental statistics.
