Low noise Preamp ASIC on HPD+ Q-T/waveform recoder ASIC
Collaboration• It is difficult to finalize Mton detector system (i
ncl. readout system) at present.– Compromise over performance and cost
Development of components (which will be adopted for Water Cherencov)
Exchange information of R&DDiscussion of Mton detector system(This can be done as we have done)

This combinationDevelopment and evaluationof ASICs with HPD
Qdet > 106 Qdet ~ 105
This R&D has been done in France
This R&D has been done in Japan
Low noise amp ASIC as FEWaveform sampler ASIC as BE
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
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
