Sat May 18 02:04:38 2024, Yoshi, Ohnishi, DAQ, RSA01 run
|
RSA01 was stopped from 19:25, it restart now. |
|
Sat May 18 01:57:44 2024, Weick, Accelerator, 96Sr isoc setting
|
We fist verified the ESR after a crash with the 98Zr setting, was fine good resolution,
then we scaled to 96Sr directly at gamma_t not with shift as before.
E_SIS = 449.21 MeV/u for 100Mo 38+
after target = 373.36 MeV/u for 96Sr 38+
in ESR = 373.60 MeV/u for 96Sr 38+
in the LISE calculation this leads to gamma = 1.40082 as before in the other settings.
yield is very low now, but some lines. |

Sat May 18 00:37:21 2024, Helmut, Wolfram, Shahab, David, Xinliang, Runs, Trying to get back to Zr setting
|
|
|
Sat May 18 00:15:44 2024, Yoshi, Ohnishi, General, Beam back
|
Beam is back, but it stopped again at 0:17...... |
|
Sat May 18 00:06:56 2024, Shahab, Runs, HHT people out again
|
we try to re run the ESR. ESR behaves very strangely. Something not so right. |
|
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. |
|
Fri May 17 23:14:51 2024, Yoshi, Ohnishi, General, shift started
|
Just test |
|
Fri May 17 22:48:14 2024, Jelena B, Accelerator, Back to old setting
|
We go back to the Zr-settings to make a deffinite state of ESR and we move again to previous setting (Sr) |
|
Fri May 17 22:43:11 2024, Jelena B, Zsolt P., Accelerator, ESR_e.cooler are back
|
We have back ESR and we have a fixed issue with a cooler.
Beam issues! |
|
Fri May 17 22:38:30 2024, Jelena B, Zsolt P., , ESR + e.cooler are back
|
We have back ESR and fixed issue with a cooler. |
|
Fri May 17 22:06:05 2024, Jelena B, Zsolt P., Accelerator, ESR
|
ESR is down |
|
Fri May 17 21:56:58 2024, Jelena B, Zsolt P., Accelerator, Optimizing setting
|
We are optimizing setting for 96Sr
start time: 21:52 |
|
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 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. |
