A time and charge measurement board for muon tomography of high-Z materials

Abstract

In this paper, a versatile time and charge measurement (MQT) board for muon tomography is described in detail. For time measurement, the general-purpose time-to-digital converter (TDC) chip TDC-GP2 is employed, while for charge measurement, digitization plus numerical integration in field programmable gate array is employed. Electronic tests demonstrate that the total 32 channels of two MQT boards have a time resolution of superior than 100 ps, with excellent linearity for time and charge measurement.
