Fri Jul 29 09:52:28 2016, Keishi Matsui, accuracy of Cf-252's intensity in RIKEN
|
According to the reply from Japan Radioisotope Association, the accuracy of the Cf-252's intensity is +0%/-15%.
( "+0%" is important, because 3.7 MBq is a standard limit for radio-active sources in Japan.) |

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.

|
A scaning with 252Cf along the Z-axis of the neutron detector is carried out. The setup is similar to the scaning carried out in October 2016.
Observations:
- Clovers are put inside the detector without voltage. |

Mon Mar 27 11:53:15 2017, PV,Liu, Turn on dE detector
|
We applied a bias voltage of 100 V to the dE detector
Current read = 0.660 uA
compare with https://elog.ph.ed.ac.uk/BRIKEN/190. it is slighly lower. |

We used the laser to align the degrader (see attached photos)
According to the LISE calculation, equivalent effective thickness for 6 mm of Carbon target is 4.5 mm thick Aluminum.
Therefore, we've set the degrader system as follow: |
