Description
A gaseous beam monitor is being developed for the CSR external-target experiment (CEE) at HIRFL. The requirements on the beam particle rate of up to $10^{6}$ pps and the per-particle position resolution of better than 50 $\mu$m pose challenge on the detector design. The beam monitor mainly consists of two drift chambers, each measuring a 1D position of the beam particle transverse to the beam direction. The detector simulation has been carried out to optimize the geometrical set-up, to evaluate the expected performance, and to calculate the requirements on the custom-designed charge sensor. We will present the simulation studies of the beam monitor, which is mainly based on the Geant4, Garfield++ and COMSOL softwares. A preliminary study of the space charge effect due to the beam particles will also be discussed.
