Inhaltsangabe:
- China's first proton test beam facility, named the High-energy Proton-beam Experiment Station (HPES), is currently under construction in campus of CSNS, as part of the CSNS-II project. Utilizing protons slowly extracted from the Rapid Cycling Synchrotron of CSNS, HPES will deliver 1.6 GeV proton beam with an adjustable flux ranging from 1E3 to 1E8 protons per second. The station is composed of two dedicated test terminals designed to support comprehensive beam tests, serving as an advanced platform for particle detector development, irradiation hardness studies of aerospace chips, and GeV-proton-induced nuclear data measurements.To characterize the beam, HPES incorporates dedicated flux and profile monitors. For user experiments, the facility is equipped with a high-precision proton telescope offering a positioning resolution of 10 $μ$m, and a Time-of-Flight (TOF) spectrometer achieving an energy resolution of 1%. Furthermore, a compatible trigger logic unit have been designed to provide precise event tagging, which is essential for data alignment. This paper presents an overview of the detector systems within HPES, discusses their design considerations, and outlines the future prospects of the facility.
