Singh (F) Expertise: In Gaseous Detectors consisting of CsI photocathode and micro-pattern detectors (GEM, Micro-strip etc.), Enough knowledge of scintillating crystal detectors. Unique experience in the design, development and engineering of Gaseous Photon detectors. Experience: Worked at Weizmann Institute Israel, INFN Italy, Columbia University USA and CERN Switzerland. 10th CBM Collaboration meeting at Dresden, Germany – V. Singh

  6. Why should we participate? •Triple GEM •Reflective CsI Photocathode Gaseous Photodetectors Application: Hadron Blind Detector (PHENIX at RHIC) D. Morrman, A. Breskin, R. Chechik and B.K. Singh Nucl. Instr. & Meth. A478 (2002) 230 • A. Breskin, A. Buzulutskov, R. Chechik, E. Shefer, B.K. Singh • IEEE Trans. Nucl. Sc. 48 (2001) 417 • Sealed Gaseous Photodetectors • (Developed @ Weizmann Institute) 10 times cheaper than a GEM! 10th CBM Collaboration meeting at Dresden, Germany – V. Singh

  7. Why should we participate? Ageing of CsI thin film photocathodes induced by UV photons B.K. Singha, M.A. Nittib, , A. Valentinib, E. Nappib, C. Coluzzac, G. Di Santoc and R.

Moro 2, 00185 Rome, ItalydDipartimento di Chimica Generale e Inorganica, Università di Roma “La Sapienza”, P.le A. Moro 2, 00185 Rome, Italy Received 30 May 2006;  revised 17 July 2007;  accepted 6 August 2007.  Available online 15 August 2007 Abstract The degradation of CsI thin film photocathodes (PCs) under Ultraviolet (UV) irradiation has been investigated by measuring the photocurrent as well as the absolute Quantum Efficiency (QE) as a function of the accumulated charge density. Atomic Force Microscopy (AFM) and UV Photoemission Electron Microscopy (PEEM) have been employed to study the surface morphology and the local QE of polycrystalline CsI thin films and their transformation due to UV irradiation. The photo-emissive properties of CsI PCs, together with their surface morphology, have been found to be strongly affected by the UV photon ageing. , 10th CBM Collaboration meeting at Dresden, Germany – V.

Singh

  12. How should we participate? • Our Proposal • Based on our experience and expertise ! • Aim is to take part SIGNIFICANTLY and at equal footing! • Work with latest technology • Application of the expertise in detector development in other fields. • Do R&D work related to detector (MuCh) 10th CBM Collaboration meeting at Dresden, Germany – V. Singh

  13. How should we participate? Plans (Hardware): To establish a well equipped laboratory for GEM detector @ BHU. To do R&D for Muon Chamber detector. Project approved.Waiting for money. Time frame: Few months! • To study the THGEM / GEM/Micromegas • Long term stability vs Rate • Understanding the effect of THGEM rim • Gain and uniformity • Ageing effects etc. 10th CBM Collaboration meeting at Dresden, Germany – V. Singh

  14. How should we participate? Plans (Simulation): CBMRoot is already installed @ BHU. Getting feeling of program. To do detector (Much) and physics simulation for CBM. Time frame: within few months! 10th CBM Collaboration meeting at Dresden, Germany – V. Singh
