Recently, our lab has quickly and effectively done single event effects experimentation simulated by pulsed laser for selecting key parts of first space science satellite "Hard X-ray Modulation Telescope (HXMT)".
One digital and analog mixed-signal application specific integrated circuit (ASIC) are key parts for science exploration, it is important to know whether it's SEE ability is strong enough to fullfil this mission. Therefore, our lab use pulsed laser single event effects facility of "Test beds for Space Environment Effects of Electronic Part, Chinese Academy of Science" to test type A ASIC and B ASIC which would be used by HXMT. Our experiments find out that type A ASIC is easily to produce single event latch-up with an equivalent LET threshold 10 MeV.cm2.mg-1 which is consistent with heavy ion test results. Type B cannot latch-up with an equivalent LET 100MeV.cm2.mg-1.
This test produce fast and economically experimental data for selecting chips used by HXMT which method can be used widely in other space science satellites and application satellites; Meanwhile, this method can produce huge economic, engineering, science and society benefits.
