Multi-gap Resistive Plate Chamber(MRPC) is a widely used timing detector of which the typical time resolution is about 50ps. This makes MRPC an optimal choice for triggering in many large physics experiments such as STAR and CBM. The prior work of improving the time resolution of MRPC has focused on altering the structure of the detector. However, the algorithm of reconstructing a more precise...
The Compressed Baryonic Matter spectrometer(CBM) is expected to be operational in the year 2024 at the Facility for Anti-proton and Ion Research(FAIR) in Darmstadt, Germany.CBM aims to study strongly interacting matter under extreme conditions.The key tool providing hadron identification at incident energies between 2 and 10AgeV is a Time-of-Flight(TOF) wall covering the polar angular range...
A new T0/Trigger detector based on multi-gap resistive plate chamber (MRPC) technology has been constructed and tested for the exteranl target experiment (ETE) at HIRFL-CSR. It measures the multiplicity and timing information of particles produced in heavy-ion collisions at the target region, providing necessary event collision time (T0) and collision centrality with high precision....
To increase the potential of fast withdrawal of RPC condition data and to eliminate the necessity of constantly decreasing manpower to run various tools, a new RPC data automation utility is being developed. Its goal is to rearrange the RPC detector currents, originally stored asynchronously in the CMS_RPC_PVSS_COND schema on cms_omds_lb database, into a new synchronous format in the...
We measured the efficiency of CMS RPC detectors in pp collisions at 13TeV using the tag and probe method. A muon from Z boson decay is selected as a probe of efficiency measurement, reconstructed using the CMS inner tracker and the rest of CMS muon systems. The overall efficiency of CMS RPC chambers during the 2016-2017 collision runs are measured to be 96% for a group of high-efficiency chambers.
CMS RPC Integrated Charge is a current related data analysis which provides one of the most significant physical parameters crucial for monitoroing the detector ageing quantities. Using the new format of storing RPC detector currents in the CMS_RPC_COND detabase schema on cms_omds_lb provides a boost in the fast calculation of the current integrated in time for every single HV channel. The...
We have tested the performance of a long MRPC(Multigap Resistive Plates Chamber) with a new type of readout of the signal induced by the minimum ionizing particles. The detector consists of 2 stacks of 6 gas gaps of 220 microns. The signal pick-up electrodes are 16 strips 8mm wide and 180cm long. One ends of the half of the 16 strips are connected to the ends of the other half using 8 LEMO...
The high luminosity expected from the HL-LHC will be a challenge for the CMS detector. The increased rate of particles coming from the collisions and the radioactivity induced in the material of the detector could cause significant damage and could result in progressive degradation of its performance. Simulation studies are very useful in these scenarios as they allow one to study difficult...
An early test shows serious “crosstalk” in the strips of the RPC detector for ATLAS Phase II. The unexpected signals on non-main strips increase the invalid counts and system load. To find the orgin of the “crosstalk”, we decide to simulate the RPC detector and change relate parameters to eliminate the “crosstalk”.
CST (Computer Simulation Technology) is a powerful simulation platform for all...
With the upgrade of the RPCs and the increase of its performances, the study and the optimization of the read-out panel is necessary in order to maintain the signal integrity and to reduce the intrinsic crosstalk.
Through Electromagnetic Simulation, performed with CST Studio Suite, new panels design are tested and their crosstalk property are studied.
The behavior of different type of panel...
The RPC detector system consists of a total of 1056 double-gap chambers, installed both in the barrel and endcap regions. Thus covering the pseudo-rapidity region up to |η| ≤ 1.9, the system contributes to all muon track finders. Establishing the correct HV working points is of primary importance in order to ensure a stable performance reaching optimal efficiency and in the same time to keep...
Abstract: The Compressed Baryonic Matter spectrometer(CBM) is expected to be operational in the year 2024 at the Facility for Anti-proton and Ion Research(FAIR) in Darmstadt, Germany. CBM aims to study strongly interacting matter under extreme conditions. The key element providing hadron identification at incident energies between 2 and 10AGeV (30 AGeV) at SIS100 (SIS300) is a Time-of-Flight...
In this work we report the procedure of the design, manufacture and assembly of a Multigap Resistive Plate Chamber at the detectors lab of ICN-UNAM. This detector consists of a stack of 5 parallel thin resistive plates (glass). The array is placed inside a hermetic box which is filled with a gas mixture of 5% SF6 and 95% freon. The main objective of this project is to reproduce technology...
By 2027, the Large Hadron Collider luminosity should increase from 1.5 × 1034 cm−2 s −1 to 5 × 1034 cm−2 s −1. For this purpose two more long shutdown (LS) periods are scheduled to give the machine and the experiments the necessary time to anticipate these luminosity increases: Long Shutdown 2 (LS2) in 2018/2019 and Long Shutdown 3 (LS3) in 2023/2025. During these long shutdown periods the CMS...
