### Speaker

Mr Chenfei Yang (1. State Key Laboratory of Particle Detection and Electronics, University of Science and Technology of China, Hefei 230026, China; 2. Department of Modern Physics, University of Science and Technology of China, Hefei 230026, China)

### Description

A high resolution X-ray imaging system based on ALPIDE, a CMOS monolithic active pixel sensor (MAPS), is presented. ALPIDE is a 15 mm × 30 mm large MAPS with 512 × 1024 27 µm × 29 µm pixels that are read out in a binary hit/no-hit fashion, and with the control and readout system, it can detect the max particle rate of 100 MHz / cm$^2$, and achieve the spatial resolution of around 5 µm. The imaging system counts the incident X-ray photon hits on every ALPIDE pixel per exposure to produce a gray scale image. Imaging results of grating patterns and insect specimens are presented.
