Bio
Sun Xiangming independently developed Topmetal series of pixel chips, and carried out a number of research and development around the application of silicon pixel chips: TOPMETAL-S, a single-electrode sensor designed for neutrino-free double-beta decay experiment, can achieve high energy resolution and high spatial resolution under the premise of ensuring stability, uniformity and scalability; A large-area improved chip Topmetal-M is designed, with pixel density increased by 4 times, detection area increased by 9 times, and all key performance indexes are up to or better than similar foreign chips. The beam monitoring system based on the self-developed Topmetal silicon pixel sensor has high sensitivity, can monitor low-intensity beam, position resolution can reach tens of microns, no electrode blocking and radiation damage, and can be used for the next generation of cancer treatment and beam monitoring of external target experiments. Topmetal-II is specially designed for low noise and low background experiments, which can work in liquid nitrogen environment. It is the electrode array with the lowest noise in the world and can collect charge, and realizes the imaging of photoelectron track. The imaging quality meets the requirements of X-ray polarization measurement, and gets rid of the dependence on foreign silicon pixel readout chips in X-ray polarization detection.
