Abstract

The paper presents the radiation test results of a readout ASIC (CASCA: Charge Amplifier with Switched Capacitor Array) for a Time Projection Chamber (TPC). The CASCA integrated 32 channels with full signal processing circuits and was fabricated in 0.18 $\mu {\mathrm{ m}}$ CMOS process. Both Total Ionizing Dose effect (TID), including static TID and dynamic TID and Single Event Effects (SEE) tests, which mainly focus on Single Event Latch-up (SEL), Single Event Upset (SEU) and Single Event Transient (SET) of CASCA were taken. The tests were taken with 200MeV and 62.8MeV protons. The radiation test setup and test results were given and discussed.
