  1. Beam Test of BGO Crystal Yunlong Zhang 2009.12.8

  2. CSR

  3. RIBLL Test counter here

  4. The configuration of beam elements and test counter T2-Si BGO counter Tof beam

  5. Dy8 Dy9 Dy10 A 10k 10k 10k 10k 300k 300k 300k 300k Readout of PMT In order to extend the dynamic range of readout, we use multi-readout from the dynodes. 1R=300K, I=0.256mA at HV=1000V; 0.256W power dissipation

  6. CFD GG Time signals A A dy10 Dy9 dy8 A dy8 Enengy signals Peak ADC Data collection 22Na gamma calibration: CAEN568LC Philip7164

  7. The spectrum of 22Na under -1100V.

  8. 1000V Na22

  9. 1100V Na22

  10. Fit function:

  11. Test with proton beam Beam particles selection

  12. ORT450 ORT142 enengy signals to Peak ADC T2-SI Philip744 CFD GG ORTlogic Time signals A A dy10 Dy9 dy8 A dy8 Enengy signals CAEN568LC Peak ADC Philip7164

  13. Delta E vs E

  14. Tp=14MeV

  15. TOF T2-Si 280μm 7μm-Al foil 10μm Without Si-∆E correction

  16. TOF T2-Si 280μm T2-Si 280μm 7μm-Al foil 7μm-Al foil 10μm With T2-Si ∆E correction We have to understand why the ratio between the -odes is energy dependence?

  17. Fit function: Fit function: L = a+b*x

  18. Saturation of fluorescence?

  19. Thanks
