Description
In past decades, scientists have made many outstanding achievements in nuclear physics, nuclear astrophysics and atomic physics, biomedicine, and other fields based on accelerators. In order to promote the development of heavy ion accelerator technology and improve the research level, the next generation of the heavy ion research facility, HIAF, has been proposed. The beam energy of HIAF will reach GeV, and its operation is inseparable from the support of the beam monitoring system. The Nupix-H1, designed for the real time beam monitoring system in HIAF, has excellent position resolution and energy resolution and can simultaneously measure the energy and time information of the hit particles. Nupix-H1 includes a 64x64 pixel array, a pixel bias circuit, an analog buffer, and a digital scan readout circuit. Nupix-H1 can measure the deposition energy up to 5ke−, with ENC better than 15e− and INL better than 2.24%. The time measurement range is 22µs, and the maximum INL is 2.54%. In addition, we proposed an AC coupling method to increase charge collection efficiency.
