Layout studies of the Silicon Tracking System for the CBM experiment
نویسندگان
چکیده
The Silicon Tracking System (STS) serves the CBM experiment as a track reconstruction and momentum measurement detector. It is designed to provide high tracking efficiency and good momentum resolution for the charged particles produced in nuclear interactions in the target. As the multiplicities in central Au + Au collisions at FAIR energies reach 1000 charged particles a high granularity and low mass detector device is required. The major change in the STS layout compared to the previous versions [1] is an increased number of stations fully based on micro-strip detectors. Other changes include segmentation of the stations according to the prototype designs and introduction of passive material.

Progress with performance simulations of the CBM Silicon Tracking System
Efficient charged particle tracking and high momentum resolution are central performance requirements of the CBM Silicon Tracking System (STS). The aim of the ongoing layout studies is to design a highly granular and lowmass detector system which can track up to 1000 charged particles that are typically generated in one central Au+Au collision at 25 GeV/u projectile energy. A low-mass detector ...
متن کاملLayout studies and sensor prototypes for the CBM Silicon Tracking System
The Silicon Tracking System (STS) is the central detector of the CBM experiment. It serves for track reconstruction with good momentum measurement (of about of 1%) of all charged particles produced in high multiplicity nuclear reactions at the target [1]. For this task a lowmass silicon tracking detector system of high granularity is needed. We are currently studying the arrangement of the trac...
متن کاملSimulation of realistic detector response in the CBM Silicon Tracking System
The Silicon Tracking System of the CBM Experiment consists of eight tracking layers of silicon detectors. Each layer is an array of vertical modules containing 300 μm thick double-sided silicon strip sensors. The strip pitch is 60 μm on both sides. The sensors are segmented into 1024 strips per side. On either side the strips are tilted by +7.5◦ or -7.5◦ with respect to the vertical edge, creat...

For the fixed-target heavy-ion experiment CBM at FAIR, a low-mass silicon tracking detector system is being developed that can track at high rates the hundreds of charged particles that will be created when an intense beam of heavy nuclei interacts with the target [1]. The detector is based on silicon microstrip detector technology. Fast self-triggering front-end electronics will be located at ...
متن کاملFirst test of a prototype CBM silicon detector system in a proton beam at GSI
In September 2008, the CBM collaboration performed the first essential test of two prototype detector systems in a 2.5 GeV proton beam at GSI. The experiment at the HTD beam line in Cave C comprised prototype micro-strip detectors of the Silicon Tracking System, and gas-electronmultiplier (GEM) detectors. The detectors were coupled to a self-triggering front-end electronics and data acquisition...
