Electronics Scheme of the Plastic Scintillator Setup

(latest version)

We use the following electronics for the readout of the Plasitc Scintillator:

Power PC CES RIO 3 8064
Trigger Module GSI TRIVA3
TDC CAEN V1190A 128ch Multihit TDC
Scaler SIS 3820 VME Scaler
2x QDC CAEN V792 32ch QDC
VME Logic Unit CAEN V512 8ch 4fold Programmable Logic Unit
2x CFD home made Constant Fraction Trigger
3x NIM/ECL Conv. home made NIM to ECL Converter
AND CAEN N405 3fold Logic Unit
Logic Fan In Fan Out LeCroy 429A Logic Fan-In/Fan-Out
Fan Out CAEN N105 Dual Fan-Out 1x16
OR CAEN N113 Dual OR 12 in 2 out
Gate & Delay Generator EG&G GG8000 octal Gate Generator

Timing Scheme

The timing scheme was produced using a pulse generator (BNC BL-2, settings: rise time = 3 ns, fall time = 30 ns) simulating the detector signals from the two bases of one scintillator panel.
The start time is given relative to the output of the first CFD. Start and length are given in micro seconds.
