The SpacePix-D radiation monitor technology demonstrator

摘要

We present the SpacePix-D, a battery-operated standalone pixel detector with built-in LCD for real-time visualization of particle hits and Bluetooth for wireless access. The SpacePix-D allows the possibility of local and remote operation and it serves as a demonstrator for the new 180 nm SoI monolithic 64 × 64 pixel detection ASICs with hit counting and deposited energy measurement capability. Currently, it operates with the X-chip03 detection ASIC which can be upgraded to a new class of SpacePix pixel detectors. The SpacePix ASIC has been submitted for manufacturing and it was designed for charged particle sensing in the space environment. It features a logarithmic front-end amplifier response to cover a large required dynamic range for heavy ion detection and SEU-hardened digital circuits.
