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

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 31 st, 2007) –(37-30)M +6.9M +  = (~14 +  ) 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 –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-sensorInstall the new photo-sensor, HPK MPPC, in the outer parts of SciBar scintillators. –Increase the fiducial [total] volume. 260  260 [280  280] cm 2 (X-Y) ➪ 270  270 [290  290] cm 2 (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). Multi-Pixel Giger Mode APD –High Gain: ~10 6 –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 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. Microstructure of 100 pixel device 100 and 400 pixels 6mm 1mm 100  m 0PE 1PE 2PE, … 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? –…..
