Beschreibungen/Notizen

• The cool storage ring (CSR) external-target experiment (CEE) will be the first large-scale nuclear physics experiment at the Heavy Ion Research Facility in Lanzhou (HIRFL). The beam monitor, designed to measure the lateral position of each beam particle, will improve the precision of primary vertex reconstruction otherwise determined by the time projection chamber (TPC) and multi-wire drift chambers (MWDCs). The beam monitor mainly contains two gaseous ionization sub-detectors, each measuring one lateral coordinate of the beam. The design requirements include the spatial resolution of m, the two-particle separation capability of s, the rate capability of pps, and small material budget. It features novel front-end pixel chips for both charge sensing and readout functions. The first prototype, utilizing the common-purpose Topmetal-II-chips, has been developed and tested; the second one, deploying the custom-designed Topmetal-CEEv1 chips, is currently being assembled. In this paper we will present the detector specifications, design and test of the prototypes, in particular the charge sensing and readout chips.
