CBM-MUCH 1st two stations: GEM 3rd and 4th stations: ??? Readout ASIC: MUCHXYTER Prototype chamber built and tested at SPS-CERN with P+Pb collisions 3r and 4th stations??
3rd and 4th station history status: TDR: Straw tube detectors (double sided readout) to be built by Dubna Russian FAIR-funding modifications lead to exclusion of STT V. Peschokonov, team leader of Dubna STT group passed away Future of 3rd and 4th stations became uncertain Boundary conditions: Highest rate at the innermost region: 15 KHz/cm^2 (3rd station) : 10 KHz/cm^2 (4th station) Large area : 9 m^2 (3rd station), a factor of 2 higher for 4th station Readout Electronics requirement might be high Options: RPC (single/multi-gap) (Indian groups have experience in building RPC) GEM(inner) + RPC (outer) Straw (Never built straw, tested one obtained from Dubna) Full GEM (Extremely expensive) Readout Electronics is always Indian responsibility
RPC building our experience so far (since 2007): 1. Developed bakelite-based RPC from scratch (Thesis: Saikat Biswas) for the INO experiment 2. Built MRPC (10 nos) for STAR MTD (Thesis: Arindam) 3. Built Large size (2.4 m x 1.2 m) bakelite RPC (no-coating) for INO (Thesis: Rajesh) 4. Built several multi-gap RPCs for PET imaging 5. Built CMS RPC/INO glass RPC: thesis: Kashyap 6. Bakelite: indigenous high resistivity material (largest size) 7. CBM requires low resistivity for high rate, built one medium size 8. Procured from ALICE muon trigger chamber 9. Tested with conventional, NINO and PADI based electronics
Proposed timeline: Completion of RPC investigations: end of 2018 Completion of design, digitization, full simulation: 2018 end If successful, TDR addendum : March 2019 If not successful : options?? Start production/procurement (2022??)
