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 (upper plot) and 200nsx10 (lower plot).

ADC-TAC pair was chosen in such a way that we used during the experiment.

ORTEC TAC 567-02 and ADC 1D

We used ADC 1D for the run pf_10_10_08_00040

The width of photon peak is about 10.3 ns for old calibration.

The width of photon peak is about 32.3 ns for new calibration.
