Description
The High Energy Photon Source (HEPS), which will be the first high-energy synchrotron radiation light source in China, is currently being built in Beijing. The hard X-ray with photon energy up to 300 keV will be provided and no less than 90 high performance beamlines and end-stations will be built around the storage ring. However, even the state-of-the-art detectors cannot satisfy the requirement of various experiments.
BPIX is a hybrid pixel detector that was designed dedicatedly for the beamlines of HEPS. It works in single photon counting mode for X-ray applications. With 1.4M pixel cells sized 150μm×150μm, the full detector can operate with a frame rate as high as 1.2kHz. This paper will introduce the system design, including the newly developed detector that utilizes the TSV (Through Silicon Via) technology for fine module assembly gaps. Several new detector prototypes with new concepts will also be introduced.
