The Trigger Based on Active Target for MIS ITEP installation
Protvino, 2011. – p. 12, figs. 9, refs.: 5


SiPM was used to create the compact target consisting of 16 active elements. The ionization of each element was measured. The accuracy of each ionization measurement permitted to distinguish between one track and three track signals for 90% events. The special processor LE-80 was created using programmable decision table lookup realized in Altera programmable logic devices. The trigger signal delay is better than 80 ns. The possibility of separation of the reactions with neutral strange particles has been demonstrated using vast experimental statistics.
