  1. CBM Activities @Banaras Hindu University Arun PrakashDoP, BHU(For Banaras Group) • Out line: • Present & • Future CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash

  2. Present:Software • CBM_Root simulation software installed and working • Ready to start detector simulation • Two graduate students are working CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash

  3. Present:Hardware • Part of MuCh (Muon Chamber) • Developing GEM (Gas Electron Multiplier) Detector R & D Lab • Order placed for necessary equipments • Procuring lab accessories • Mean while with the help of other lab started studying ageing effect of GEM CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash

  4. Photon ageing Q.E [%] Accumulated charge (uC/mm2) Wavelength [nm] B.K. Singh et al., NIM A 581 (2007) 651 CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash

  5. Surface morphology (AFM Technique) After 5 days of photon ageing Before Photon ageing B.K. Singh et al., NIM A 581 (2007) 651 CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash

  6. PEEM & AFM images of aged CsI 40 um B.K. Singh et al., NIM A 581 (2007) 651 CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash

  7. 1mm Cu G-10 MICROPATTERN DETECTORS Chechik et al. NIM A535 (2004) 303 Shalem et al. NIM A558 (2006) 475 Manufactured by standard PCB techniques of precise drilling in G-10 (+ other materials) and Cu etching. ECONOMIC & ROBUST! Standard GEM THGEM Hole diameter d=0.3 - 1 mm Distance between holes a=0.7- 7 mm Plate thickness t=0.4 - 3 mm 103gain in single-GEM 105 gain in single-TGEM Breskin/weizmann 0.1mm F. Sauli (CERN) 0.1mm rim:prevents discharges  high gains! CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash

  8. Future:-Software • Very soon we will start simulation study of absorbing materials in MuCH • Plan for other detector and physics simulations CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash

  9. Future:-Hardware We will study:- • Ageing effects • R&D for TH-GEM CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash

  10. Conclusion:- Activities started @ BHUSoon full fledge activity will start for CBM Thank you !! CBM Meeting @ Jammu University Feb. 12-16, 2008 by Arun Prakash
