Fri Dec 1 07:29:47 2017, Vi Ho Phong, [Hardware][Configuration] Return the PB-5 Pulse generator (Pulser 2) and the 428F Linear Fan in-out modules and replace with a new Linear Fan in-out module 7x
|
The PB-5 Pulse generator labeled "Pulser 2" and the 428F Linear Fan in-out labeled "Clover G7" from BRIKEN NIM crate have to be returned to the RIBF electronics
pool because the
borrowing time is expired.

Here is a doc with an estimate of the statistical uncertainty P1n and P2n as a function of the number of implant-beta correlations for future
experiments. |

Wed Oct 25 19:14:09 2017, NB, First pass efficiency for current experiment
|
I roughly (~10%) checked the efficiency for 4 of the peaks from 171025_1222_1355_152EuCloverCal.root.
I checked the peaks at 122, 245, 344, and 1408. The indication is an efficiency of 6.9, 9, 9,8, and 2.6 % for these gamma rays
repectively. |

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 |
