Abstract

We have developed an ultra-fast multi-hit TDC to improve the momentum resolution in the multiple coincidence momentum imaging spectroscopy. The TDC consists of 12 bit/100 MHz crystal oscillator counters and seven time-to-amplitude converters. The TDC receives signals up to 6 as start pulses and one signal as a stop signal. The time resolution of the TDC is about 120 ps under the time span of 40 μ s. Using the present TDC, we have obtained the vibrational-resolved core-level photoelectron momentum distribution of CO molecules in coincidence with two fragment ions.
