Performance of A DTBX Prototype
No full textA novel muon detector concept for LHC was studied in a test beam. The application of mean-timer technique to arrays of drift tubes provides the space and time resolution needed for first level trigger and track reconstruction using only the drift time information. A complete study of the performance of this new detector was done
FURTHER-STUDIES ON A DTBX PROTOTYPE FOR THE CMS MUON DETECTOR AT LHC
No full textThe performance of a small prototype chamber of the baseline project for the muon barrel detector for CMS has been studied in a muon beam. Its efficiency with different gases and wire diameters, the trigger possibilities and the response in presence of a large number of electromagnetic secondaries associated to the muon are evaluated. The results are compared with a full Monte Carlo simulation
Bunch crossing identification at LHC using a mean-timer technique
No full textA novel method was developed to obtain precise timing of muon hits in drift tubes at the first trigger level, and hence to associate a detected muon with the bunch crossing in which it originated. A very good time resolution of approximately 2 ns was obtained. Some other topics related to muon detection were investigated
TEST OF A RESISTIVE PLATE CHAMBER OPERATING WITH LOW GAS AMPLIFICATION AT HIGH-INTENSITY BEAMS
No full textWe present results on efficiency and time resolution of a resistive plate chamber operating at low gas amplification. The measurements were done within the programme of the RD5 experiment at CERN with a pion beam of flux 0.1-3.9 kHz/cm(2)
Parallel plate chambers: a fast detector for ionizing particles
No full textThe parallel plate chamber technique is summarized together with recent results of tests concerning efficiency, time resolution, high rate capability and radiation resistance. © 1994
STUDY OF RESISTIVE PLATE CHAMBERS FOR MUON DETECTION AT HADRON COLLIDERS
No full textWe present the performane of a hodoscope made of resistive plate chambers (RPC) installed in the RD5 experiment at CERN and exposed to beams of high energy muons and pions. The efficiency as a function of the particle flux is studied for different resistivities. A substantial improvement is obtained with plates of lower resistivity. Tracking muons through the RPC and using the bending power of a 2.7 Tm iron toroid, a simple trigger algorithm is used to select large momentum muons
