主 题:Hybrid silicon pixel module Test and calibration Power management Through silicon via and wire-bonding HEPS
摘 要:Background HEPS-BPIX is a prototype of photon counting pixel detector developed for the High Energy Photon *** consists of 16 silicon pixel modules which should be tested individually to ensure the function and *** Due to various factors such as the non-uniformity of the processes and voltage drop,the response of each pixel in the silicon pixel module is not identical *** response difference of pixels can be minimized by the threshold *** system is developed for the quality test and calibration of the silicon pixel *** The system consists of a mother board,a control board and a data acquisition(DAQ)*** mother board provides necessary resources including power supplies and the fanout of calibration ***,it can be used to test the connectivity by monitoring the power *** control board reads data out and provides the clock,trigger and configuration data for the silicon pixel *** DAQ system sends the control commands and receives the readout data through an Ethernet *** Compared with the previous readout system,this designed system has a lower noise level and better scanning curves making the calibration more *** it has been successfully applied to the comparison experiments of the through silicon via and wire-bonding silicon pixel *** The results show that this test system can be used to the quality test and calibration of the silicon pixel *** addition,the system can be adapted to the measurement of different pixel array detector modules.
