We used:
-detector A to calibrate all the TDCs;
-LeCroy octal discriminator to produce standard negative pulses;
-passive delay line to calibrate TDCs in the region < 100 ns;
-delay amplifier TENNELEC TC215 to calibrate TDCs in the region > 250 ns;
Range of all three TDCs was set to 50nsx100.
ADC-TAC pair was chosen in such a way that we used during the experiment.
ORTEC TAC 567-02 and ADC 1D
ORTEC TAC 567-01 and ADC 1A
ORTEC TAC 566-01 and ADC 1C
