Wed Oct 25 01:02:14 2017, RG, Status of the YSO array
|
The presently used detector has 48x48x5 mm3 YSO array with 1x1mm2 segments. They are separated with ESR. We use H8500 pspmt and 2 mm quartz diffuser
with rough edges. Coupling is done with sylgard. Anger logic uses a conventional resistive network with 1kohm and we have 4 position signals and
dynode. The position signals (xa,xb,ya,yb) are split in Low gain branch connected directly to 5V range input in Struck and High gain branch, which |

Tue Nov 8 02:49:19 2016, PV, Liu, Specification of the dE silicon detector
|
The specification and picture of the dE silicon detector is shown in the attached photos.
The detector has an effective area of 134 x 123 mm and 320 micrometer thick
There are 26 vertical strips. They are combined into 2 readout channels (top and bottom which respect to the orientation of the detector in BRIKEN) |

Tue Nov 29 00:30:42 2016, PV,SN, Sillicon dE bias voltage increased
|
We increase the bias voltage of the dE detector from 20 V to 100 V
Leakage current:
Before: ~0.590 uA |

Tue Nov 8 17:00:27 2016, NTB, CG, AT, Si Delta E
|
At least during the timeframe in between ~ 21:30 (11/08) - 23:30 (11/09) (161108_2323_717273Ni.root) we see that the silicon dE have a very low counting
rate. ~1Hz when the first AIDA detector sees ~600 Hz and a cumulative ~2kHz. The energy range in the dE stops at ~10MeV.
Edit: It appears the Si dE were removed. Some signals are still in the spectra. |
