Description
Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) is a free electron laser facility operating in the hard X-ray energy region, which is currently under construction in China. STARLIGHT(SemiconducTor Array detectoR with Large dynamIc ranGe and cHarge inTegrating readout) is a charge integration pixel detector system with a frame rate of 10 kHz and a large dynamic range up to 10000 photons at 12 keV, which will be deployed on several experimental stations of SHINE. Each pixel on the STARLIGHT uses dynamic gain technology that automatically switches between three gain modes.
The readout ASIC in the front-end module of STARLIGHT is HYLITE (High dYmamic range free electron Laser Imaging deTEctor). HYLITE200F , which is implemented by a CMOS 130nm process, is the first full scale chip of HYLITE with 64×64 pixels and a pixel size of 200 μ m ×200 μ m. The chip operates is single-photon sensitive with a signal-to-noise ratio of 6.5.
In this paper, we will display the performance test results of HYLITE200F and a small scale front-end module. The bump-bonding process was applied to connect four HYLITE ASICs and one Si-PIN sensor. Test results show that the gain of HYLITE200F chip has good uniformity. At the same time, when the energy of the incident photon is 12 keV, the chip remains 3% non-linearity with a dynamic range of 10,000 photons. The frame rate of HYLITE200F is 6.3 kHz in a successive readout mode. Furthermore, the test module illuminated by an X-ray tube accomplish the imaging experiments successfully.
