 Wed May 15 01:11:45 2024, David, Asahi, Shahab, Chris, Ruijiu, General, Time optimisation
|
DAQ stopped at 01:11 to optimise data taking cycle of RSAs.
Changed data writing time from 2s -> 1.8s. |
Wed May 15 02:07:02 2024, Chris G, Asahi Y, General, No beam to ESR 
|
Injection to ESR stopped around 02:04:45.
Will continue to write data in hope that beam returns shortly. |
|
Wed May 15 02:12:59 2024, Chris G, Asahi Y, General, Beam returned to ESR
|
Injection to ESR restarted around 02:12:15 |
|
Wed May 15 09:35:08 2024, Beatriz, Min, General, No beam
|
At 9:32 we lost the beam. They have to work in the Unilac and there will be no beam for 45 minutes. |
|
Wed May 15 10:58:32 2024, Beatriz, Min, General, Beam returned to ESR
|
Beam recovery at around 10:52:30. Sergey and Yuri still tuning the mass resolution. |
|
Wed May 15 13:39:10 2024, Beatriz, Min, General, ESR setting
|
From 13:37 ESR will be changed again. Now back to the primary beam, it will be attempted to measure the orbit of the beam. |
|
Wed May 15 16:55:10 2024, Jeroen, Johan, General, Tuning ESR scraper. Isomer resolved.
|
4:50 Scraper tuned to produce Gaussian beam profile for 98Mo. Isomer now clearly resolved.
Plan to take data for 98Mo fragment for 12 hours. Measurements from 4:59 are now aligned so that the Molybdenum fragment is centered in the RSA acquisition. |
|
Wed May 15 17:45:09 2024, Jeroen, Johan, General, No beam to ESR
|
Beam lost from SIS18 at 17:41:41. |
|
Wed May 15 17:47:34 2024, Jeroen, Johan, Shahab, General, New Trigger Setup
|
We changed the trigger setup, see attachment |
|
Thu May 16 18:55:38 2024, Ide, Hubbard, General, new timing cycle
|
new timing cycle of 6.7s |
|
Fri May 17 16:34:43 2024, Jelena B, Zsolt P., General, Beam issues
|
We lost beam at 16:29.
Cooler has to be investigated. |
|
Fri May 17 16:42:00 2024, Jelena B, Zsolt P., General, Beam back
|
Beam is back at 16:38.
We are changing the setting. |
|
Fri May 17 20:33:43 2024, Jelena B, Zsolt P., General, Beam returned to FRS
|
We have again beam at FRS..
But we are taking still cycles on a same way as before...and discussing to go back to the old zirconium setting
In one hour HHT will enter the cave. |
|
Fri May 17 21:44:39 2024, Jelena B, Zsolt P., General, Beam issues
|
We do not have beam, and we have some instability during last 1-1.5 hour. |
|
Fri May 17 23:14:51 2024, Yoshi, Ohnishi, General, shift started
|
Just test |
|
Fri May 17 23:30:16 2024, Shahab, General, HHT people inside
|
no beam since about one hour, also HHT people inside since about 10 min. |
|
Sat May 18 00:15:44 2024, Yoshi, Ohnishi, General, Beam back
|
Beam is back, but it stopped again at 0:17...... |
|
Mon May 20 09:01:51 2024, Oliver, Jelena, General, Shift news
|
Data collection runs smooth so far.
Yuri Litvinov will start modifying SP magnets now. The resolution will change. |
|
Mon May 20 13:26:55 2024, Jelena, Oliver, Shahab, General, Plunger values
|
plunger 150 for 250
plunger 48 for 410 |
|
Mon May 20 13:31:09 2024, Jelena, Oliver, Shahab, General, New setting focussing on 96-Sr
|
plunger 150 for 250
plunger 48 for 410
From file starting from 13:21 is a new setting for 96Sr. |
