在GIF ++上使用自触发电子设备的酚醛树脂原型RPC的性能,用于FAIR的CBM实验
Performance of a prototype bakelite RPC at GIF++ using self-triggered electronics for the CBM Experiment at FAIR
摘要:
μ子室(MuCh)是压缩重子物质(CBM)实验的一个子系统,用于探测束流能量在2 AGeV到11 AGeV的高能重离子碰撞中产生的低质量矢量介子,并在双μ子通道中衰变。MuCh由一个分段的吸收体和夹在吸收体段之间的四个检测器三重态站组成。在MuCh的第三和第四站,电阻板室(RPC)已被设想用于μ子跟踪。我们已经测试了一个低电阻率胶木RPC原型的性能,配备了自触发前端电子(MuCh-XYTER)的煤层气μ子室。在欧洲核子研究中心(CERN)的γ辐照装置(GIF++)上,对高速光子背景下μ子的探测效率和时间分辨率进行了系统的研究。测量设置和结果的详细信息在这里给出。
英文摘要:
The Muon Chamber (MuCh) is a sub-system of the Compressed Baryonic Matter (CBM) experiment for the detection of low-mass-vector mesons produced in high energy heavy-ion collisions at beam energies ranging from 2 AGeV to 11 AGeV and decaying in the di-muon channel. MuCh consists of a segmented absorber and four detector triplet stations sandwiched between the absorber segments. At the 3rd and 4th stations of MuCh, Resistive Plate Chambers (RPCs) have been conceived for muon tracking. We have tested the performance of a low resistivity bakelite RPC prototype equipped with self-triggered front end electronics (MuCh-XYTER) for the CBM Muon Chamber. A systematic study on the muon detection efficiency and time resolution has been carried out in a high-rate photon background at the Gamma Irradiation Facility (GIF++) at CERN. The details of the measurement setup and the results are presented here.
