CMS - Compact Muon Solenoid

Scientific Programme:

The CMS Collaboration has proposed a general-purpose detector to be operational at the start-up of the Large Hadron Collider (LHC/CERN) to exploit its full discovery potential.
The CMS design objectives:
(1) a very good and redundant muon detection system;
(2) the best possible e/

calorimeter consistent with (1);
(3) high-quality central tracking to achieve (1) and (2).
The major activities of JINR are focused on the following directions:
- preshower detector for electromagnetic calorimetry;
- cathode strip chambers for forward muon stations;
- forward hadron calorimetry;
- simulation;
- heavy-ion interactions.

Expected main results in 2001:

Mass-production of cathode strip electrodes and panels for the chambers.
Development of CSC mass-production facility at JINR. Design of the technical documentation for the serial CSC.
Mass-production of absorbers, interface systems and assembly tooling for endcap hadron calorimeters in co-operation with NC PHEP BSU (Minsk) and HTTC NIKIET (Moscow) at MZOR plant (Minsk). Participation in mass-production of the scintillation optics for endcap hadron calorimeters in co-operation with IHEP (Protvino), ISC and NSC KIPT (Kharkov). Delivery and start of assembly of the first endcap hadron calorimeter at CERN.
Production in co--operation with SPJ ELMA (Zelenograd) and measurement of parameters of the serial silicon strip detectors. Radiation test of the serial silicon strip detectors with neutrons flux of 2·10 ¹⁴cm².
Design of CSC read-out electronics parts in co-operation with NC PHEP BSU (Minsk) and HV and LV systems in co-operation with INRNE and US (Sofia).
Simulation of physics processes for CMS experiment in proton--proton and nucleus--nucleus interactions.
Provision of computer communication for data exchange between members of the experiment.
