  8. What information will we need in future (construction, operation) from test bench? • • We will save all raw data and check all measurements, but it will be too much to • handle for later use • • Construction needs: • • to reject ‘bad’ ones (screening) • • to sort devices (e.g. by Vbd) • • Operation needs: • • Calibration will be done in situ, anyway • • Still we need ‘firm’ reference point • • I propose following to start discussion Your inputs are really welcome • Serial ID (TA0001, TB0001, ....) • • Breakdown voltage and gain slope for 3 temps • • Noise rate (>1pe) at a fixed ΔV (for 3 temp) • • PDE at a fixed ΔV (expect no temp/device dependence) • • Cross-talk + afterpulse at a fixed ΔV (expect no temp/device dep.) • • Hamamatsu test data • • Any note during measurement(?) • Do we need more points? http://www.nd280.org/ngrid/Meetings/ingridmeetingllr/ MPPC test bench at KYOTO testy MPPC w KYOTO i u Francuzów

  9. Where do we find those information with new packaging ? • What do we have to measure ? • Reverse current vs Vop & T° (Vbr+ΔV) • Gain vs Vop & T° • Dark Noise Rate vs Vop & T° • Photo detection efficiency P.D.E. (relative to PMT) Measured Gain 7.67E+05 To be compared with value on MPPC bag M=7.50E+05 Dark Noise Rate350 KHz value on MPPC Bag : 378 kHz (~0.5pe) Optical Crosstalk : 25 kHzvalue on MPPC Bag : 25 kHz(~1.5pe) http://www.nd280.org/ngrid/Meetings/ingridmeetingllr/ Meeting on 2008/03/20-21 MPPC test bench at LAL testy MPPC w KYOTO i u Francuzów

  10. Information in databasePropozycja Francuzów KYOTO • MPPC ID • Kyoto / LLR • Hamamatsu data • gain, • Vop, • Noise 0.5 p.e., • Noise 1.5 p.e. • Vbd, Slope @15, 20, 25 °C • Noise rate @0.5 p.e. 15, 20, 250CDV = 1.4 V • PDE DV = 1.4 V @ 20 °C • Cross-talkDV = 1.4 V @ 20 °C • After-pulse DV = 1.4 V @ 20 °C • Czy nie chcą mierzyć Noise Rate @ 1.5pe?? • Serial ID (TA0001, TB0001, ....) • • Breakdown voltage and gain slope for 3 temps • • Noise rate (>1pe) at a fixed ΔV (for 3 temp) • • PDE at a fixed ΔV (expect no temp/device dependence) • • Cross-talk + afterpulse at a fixed ΔV (expect no temp/device dep.) • Hamamatsu test data • Any note during measurement(?) Proponują zapisanie w Data Base takiej samej informacji. Pewnie trzeba by się dostosować. http://www.nd280.org/ngrid/Meetings/ingridmeetingllr/ Meeting on 2008/03/20-21 Porównanie: MPPC Test Bench at LAL and Test Bench at Kyoto testy MPPC w KYOTO i u Francuzów
