| 内容記述 | We report on the performance of ananalog application-specific integrated circuit(ASIC developed aiming for the front-end electronics of the X-ray CCD camera system on board the next X-ray astronomical satellite,ASTRO H. It has four identical channels that simultaneous lyprocess the CCD signals. Distinctive capability of analog-to digital conversion enables us to construct a CCD camera body that outputs only digital signals. As the result of the front-end electronics test,it works properly with low input noise of r30 mV at the pixel rate below 100kHz. The power consumption is sufficiently low of ˜150 mW=chip. The input signal range of 7 20 mV covers the effective energy range of the typical X-ray photon counting CCD (up to 20keV). The integrated non-linearity is 0.2%that is similar as those of the convent ional CCDs in orbit. We also performed a radiation tolerance test against the total ionizing dose(TID) effect and the single event effect.The irradiat ion test using 60Co and proton beam showed that the ASIC has the sufficient tolerance against TID up to 200krad, which absolutely exceeds the expected amount of dose during the period of operating in a low-inclination low-earthorbit. The irradiat ion of Fe ions with the fluence of 5.2*108 Ion/cm2 resulted in no single event latchup(SEL), although there were some possible single event upsets. The threshold against SEL is higher than 1.68MeVcm2/mg, which is sufficiently high enough that the SEL event should not be one of major causes of instrument downtime in orbit. | |||||
