Mon Nov 5 09:59:36 2018, MW, KR, suspicious clover G7 temp sensor
|
We observed 6 pm LN2 filling of both clovers on Monday Nov 5th.
D4 went full within reasonable time of below 10 minutes.
Filling of G7 was stopped by "emergency sensor" after about 15 minutes of filling. |

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.) |

With detectors still on the floor we check signals and found
that D4 gives no signal with PA power. Two power supplies/cables were checked.

|
Green and Red channels were repaired by crimping and securing the grounding of the cables and fixing the cables securely to the table.
All problems during the repair process were visible on the scope. See example attatched.
Calibration is as: |
