Ohishi (HPK) Contents Merits of Gas PMT Quantum efficiency in gas mixtures Ion and Photon Feedbacks Long time operation of the Gas PMT A new type of double mesh structures Development of a flat pixel detector Summary 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 1

2 Merits of Gas PMT Sensor type Sensitivity Position Resolution Timing Resolution Uniformity Price Magnetic Field Effective Area Vacuum PMT CCD / CMOS Gaseous PMT Almost immune to magnetic field Fine-mesh Dynodes PMT 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 2

3 QE in gas mixtures Bi-alkali Photocathode in Ar(90%) + CH 4 (10%) 0.9 atm QE in vacuum ~20% QE in the gas ~12% After evacuation QE recovered to ~20%. 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 3

4 Relative 相対ゲイン gain Stability of PC in Ar+CH 4 gas Long term stability 経時変化 ZM642 ZM627 QE maintains almost the same value after 581 days in gas Not continuously illuminated Period 時間 (days) [ 日 ] 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 4

8 Collection efficiency for Ne+CF 4 gas 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 8

9 Possible problems: Ion and Photon Feedbacks During amplification process in avalanche, a lot of electrons and ions are produced together with many UV photons. Ions and UV photons can hit photocathode. 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 9

10 Suppress photon feedback Glass CP may reduce Photon Feedback. But ion back flow rate is 0.3 in this case. Ions Electrons 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 10

11 Suppress ion feedback Mesh electrode (Micromegas) absorbs ions efficiently. Ion back flow rate is less than 0.01 for this case. Measured 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 11

12 Long time operation of the Gas PMT After 180 hours of operation, 20% decrease of the signal output was observed. Gain: 670 IBF: 0.32% 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 12

13 Long time operation of the Gas PMT Gain: 670 IBF: 0.32% Accumulated ion on PC : 1.5 nc/mm 2 The peak channel was shifted to lower channel (about 20%) than that obtained at 0 h. The energy resolution were 18.2% (FWHM) and 19.0% (FWHM), respectively, for 0 h and 180 h after operation. 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 13

14 A new type of double mesh structures For further reduction of ion back flow a new type of double mesh structure was tried. Drift 28 V/cm 80 mm Pitch 250 mm Mesh1 A new structure (top view) DV 1 =525 V (15 kv/cm) 120 mm 350 mm 190 mm DV 2 =500 V (25 kv/cm) 200 mm Mesh2 Mesh1 Mesh2 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 14

22 2D readout of flat panel Gas PMT Pattern of the mask 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 22

23 Summary Gas PMT has merits compared with vacuum type PMTs: immune to high magnetic field (~1.5 Tesla) simple dynode structure -> large size with less money Long term stability: need to suppress ion feedback Staggered hole structure with double meshes may work. 2 D imaging was tried with a pixel anode Gas PMT. Nonuniformity was observed: under investigation. 2014/7/1 NDIP2014(Tours) T. SUMIYOSHI 23
