Abstract

Abstract:

The time resolution of a radiography system for high-Z materials shall be at least 1 ns, hence the need of a time measurement system with a resolution of about 100 ps. In this paper, a Time Measurement Evaluation Board (TMEB) is developed to meet the need. It is based on the time-to-digital converter of ACAM TDC-GP2. Test results show an overall time resolution of 81 ps in detecting cosmic-rays with a plastic scintillator.

Key words: Radiography, Time measurement, TDC, CFD, Resolution, Linearity
