Fig. 9From: High-energy electron experiments (HEP) aboard the ERG (Arase) satelliteVATA460.3 gain of all a HEP-L and b HEP-H channels of SSD modules. The dotted vertical lines indicate the first channel of each ASIC. The strips in the first layer are read out with three ASICs, and those in the lower layer are read out with two ASICs per layer. Therefore, 9 and 17 ASICs are used in the HEP-L and HEP-H SSD modules, respectively. Channels 0–95, 288–384, and 576–672 of HEP-L, and channels 0–95, 544–640, and 1088–1184 of HEP-H correspond to the first layer, which is the 50-μm-thick SSDBack to article page
