  1. SciBooNE Meeting @January 16, 2007 Japan-US Research Budget 2007& SciBooNE Upgrade T. Nakaya (Kyoto)

  2. Japan-US status • 2006 (the last year) • 30Myen (~US$250k) for equipments • 37Myen (2006), 6.9Myen (2007), 8Myen (2008) were requested at the beginning of SciBooNE. • 5.6Myen (~$50k) for travel • 6.5Myen was requested • 2007 (Proposal deadline is January 31st, 2007) • (37-30)M +6.9M + a = (~14 + a=10) Myen will be requested for equipments. • ~8Myen (6.0 Myen expect) for off-line computing w/ RAID disks. • ~8Myen (6.0 Myen expect) for upgrade. • ~3Myen (2.0 Myen expect) for others (rental car, etc..) • (~5Myen for T2K Muon monitor test at the NuMI beam line.) • 5 Myen will be requested for travel. • Additional 2.5 Myen from JSPS for travel [approved]

  3. Japan-US Budget Status (in confidential?) • In 2007, MEXT (A Japanese funding agency) reduces the preliminary plan of budget for Japan-US because the agreement for energy research between Japan and US was expired in 2005. • 873Myen (2006) → 442Myen (2007) • KEK director is under negotiation with MEXT. We do not know the final outcome yet. • IPNS director recognizes the importance of SciBooNE, and I guess that the impact to SciBooNE is not large (my guess).

  4. 1. Off-Line Computing (and spares for online equipments) • We will request 8Myen (~$65k) for offline CPU, RAID disks and some of online spares, and will get ~6Myen (~$50k) in my guess. • ~$20k for Off-line CPUs • ~$20k for RAID disks. • ~$10k for spares? • If you think that it is not large enough, I will increase the request to Japan-US. Let me known by the end of this week.

  5. 2. SciBooNE Upgrade • Install the new photo-sensor, HPK MPPC, in the outer parts of SciBar scintillators. • Increase the fiducial [total] volume. • 260260 [280 280] cm2 (X-Y) ➪ 270270 [290290] cm2 (X-Y):~8% increase • Test for T2K-ND280 • HPK MPPC will be used for T2K-ND280 2ch64 layers 4(2X+2Y) =512 channels are now empty.

  6. HPK MPPC (Multi-Pixel Photon Counter). 100 and 400 pixels 6mm • Multi-Pixel Giger Mode APD • High Gain: ~106 • Compact • Low Voltage operation: ~70V • High QE for a WLS fiber readout. • 2~3 times higher than MAPMT • Cheaper than MAPMT per channel. • Available from Nov. 2006. • 150 MPPCs in Kyoto now • High single photon noise rate • O(100kHz) Yokoyama-san is the leader of the T2K-ND280 photo-sensor group. • You can ask details to Yokoyama-san. 1mm Microstructure of 100 pixel device 100mm 1PE 2PE, … 0PE ADC distributions for LED light.

  7. What are necessary for upgrade w/ MPPC? • Scintillators: Exist in SciBar • WLS fibers: will be purchased or we have them at KEK. • 600ch  3m = 1.8km {~$5k} • MPPC: will be purchased by J-US in June. • I cannot show the price yet. It is within our budget. • Readout Electronics • Will be supplied by UK which develops the proto-type electronics for T2K-ND280. • Installation • During Summer shutdown.

  8. SciBooNE J-US budget 2007 • Don’t I miss some important items? • If you have a proposal to improve SciBooNE, please inform me by the end of this week (1/20). We may have a chance to include your proposal. • Slow monitor Upgrade? • …..
