Presentation Transcript

  1. New photon detector R&D for Megaton water Cherencov detector MT 2007 May09

  2. Photocathode Scint PMT R&D -two direction- Hybrid Photon Detector HybridPMT PMT Low noise Preamp ASIC on HPD + Q-T/waveform recoder ASIC Multichannel FE ASIC, close to the PMTs

  3. Collaboration • It is difficult to finalize Mton detector system (incl. readout system) at present. • Compromise over performance and cost Development of components (which will be adopted for Water Cherencov) Exchange information of R&D Discussion of Mton detector system (This can be done as we have done) Next slide TV conference etc

  4. R&D - Development of components- Photocathode Scint PMT Qdet > 106 Qdet ~ 105 This combination Development and evaluation of ASICs with HPD This R&D has been done in France This R&D has been done in Japan Multichannel FE ASIC, close to the PMTs Low noise amp ASIC as FE Waveform sampler ASIC as BE

  5. Benefits which can be gained from FJPPL • For both sides • Save manpower for ASIC development • Cross measurements decrease bugs • For Japanese-side • Access new technologies (AMS 0.35um process) with low risk • For French-side • Know-how of construction of large water Cherencov detector through discussion

  6. Plan and status • Evaluation of FE-ASIC(MAROC2) with HPD in Japan. • Tested at LAL • Received on April • ASIC design based on the result.（FY2007 fall) • Done by us (collaboration between F-J) Applicable ASIC for Not only HPD but also multi-pixel HPD
