16 Development in Large Format PMT PMTs for Deep Sea Neutrino Experiment 13 inch PMT, 20 inch Short Type PMTs for Megaton Type Detector Feasibility study for mass-production Feasibility study for mass-production Large Format HPD for T2K Experiment High performance (Good S/N Ratio) High performance (Good S/N Ratio)

17 8 inch10 inch 13 inch 20 inch Large Format PMT Lineup 13 inch PMT is shorter comparing to its diameter.

18 Large Format PMT Series Part No.DiaEffective Area TTSP/V (Peak to Valley Ratio) R ns2.5 R ns2.5 R ns2.5 R ns1.7 R ns2.5

19 Electrodes and Metal Shield Heating for sealing process damages dynode surface. Metal stem flange can avoid the heating problem. Dimensional Outline of R8055 Metal Stem Flange

20 17 inch glass sphere R8055 is suitable for 17 inch glass sphere !! R8055 (13 inch PMT) This electrode was developed for R7250, which is used for KamLand experiment in Japan. 17 Glass Sphere with R8055

21 R (20 inch) 11,000 tubes for SUPER-K Largest in the world 610 mm

22 Modification of 20 inch PMT Present 20 inch PMT Modified 20 inch PMT 526 mm Metal Stem Flange 610 mm 25 inch Glass Sphere too long !!

23 Feasibility Study for Mass-Production (not official) to Improve Productivity of 20 inch PMT 1. Simple Structure for easy production 2. Unique Facilities for better efficiency Early –Stage Estimation 100K tubes in 5 years (20K tubes per year) Number of Employees : 50 peoples PMT Price : $2,000 We are checking whether glass bulbs can be supplied from glass venders without big problems or not.

24 Hybrid Photo-detector (HPD) R7110U-40 (TO-8 Type) R9503U-04 (Proximity Type) Large Format Type (Development) Good PHD and CE Good Uniformity Immunity to Magnetic Field 8keV Avalanche Gain X 50 Photocathode (-8kV) Photoelectron Output Light APD Electron Bombardment X1200 Combination of EB and avalanche gain

25 Pulse Height Distribution HPD PMT 1pe 2pe 3pe 4pe 5pe 1pe K-APD = 12KV

26 Sketch of 5 inch HPD APD Target (3 mm in dia.) 180 mm Effective Area (80 mm in dia.) 5 inch HPD was made as feasibility study for larger size. Glass bulb of 5 inch hemispherical PMT was used. HPD : Hybrid Photo Detector sealing tape for protection

27 Next Step of Large Format HPD 1.13 inch HPD is being developed with collaboration of the Univ. of Tokyo and JST(JAPAN SCIENCE AND TECHNOLOGY AGENCY). 2.Working prototype would be made in 2 years (by mar.2007). 3.Development will be finished by Mar.2010.
