Abstract: With the aim of simulating the harsh temperature condition of space, a thallium-activated cesium iodide crystal (CsI:Tl) detector readout with a PIN photodiode (CsI:Tl(PD)) and with a silicon photomultiplier (CsI:Tl (SiPM)) is investigated over a temperature range from - 40 to 40 oC. With the increase in temperature, the output signal increases by ~ 24% with CsI:Tl(PD) and decreases by ~ 69% with CsI:Tl(SiPM). To reduce the effect of temperature in outer space, a method of bias voltage compensation is adopted for CsI:Tl(SiPM). Our study demonstrates that after correcting the temperature the variation in the analog-to-digital converter’s amplitude is <3%.
