Fri Apr 4 08:53:30 2025, Nic, Magda, Ragan, Jan, General, Beam Break
|
Intensity dropped a lot, ion source fix ongoing
ESR access for 5-10 mins to restart PLEIADES DAQ
FRS has also taken beam again, so ESR is sharing
08:55: ESR closed and takes beam again |

STOP RSA for beam tuning |
|
Tue Apr 8 20:29:24 2025, Michael, Shahab, DAQ, new DAQ settings
|
NTCAP Started
RSAs started:
New plunger settings for 410 --> 20mm
frequencies: 410 -->
245 -->
recording time: 1.7s
ACQ BW--> 5 MHz
fs --> 6.25 MSPS
trigger --> 8%
lframes = 65536
nframes = 160
first good file in this setting is: 20:34 onwards |
|
Tue Apr 8 14:16:16 2025, Michael, Cagla, General, Beam stopped for Accelerator Tour etc.
|
The beam was stopped for the evaluation accelerator tour. RSAs and NTCAP stopped now. |
|
Wed Apr 2 10:05:06 2025, Michael, Alex, Yuri, Accelerator, No beam since 09:59
|
The SIS kicker has failed again. |
|
Wed Apr 2 10:55:16 2025, Michael, Alex, Wolfram, Accelerator, No beam in the ESR
|
Since few minutes do not see any beam in the ESR (on RSAs). There is beam in SIS and injection requests from the ESR seem to be there as well. |
|
Wed Apr 2 13:27:52 2025, Michael, Alex, Maeve, Accelerator, No beam in the ESR
|
There is no beam in the ESR since couple of minutes. According to the info from HKR, the experts started to repair the magnets (power supplies) used for extraction and transfer of the beam from SIS to ESR. It is estimated to take about 1 hour. |
|
Wed Apr 2 13:35:17 2025, Michael, Alex, Maeve, DAQ, RSAs data taking
|
Since there will be no beam for about one hour, the data taking in RSAs has been stopped. |
|
Wed Apr 2 15:07:52 2025, Michael, Alex, Maeve, Accelerator, Still not a good beam in the ESR
|
The (power supply of) SIS kicker magnet has been repaired and the beam has been restored from about 14:20.
But, the Schottky spectrum in the ESR looked pretty bad, so the measurement can not be restarted.
The accelerator experts are currently looking into this problem. |
|
Wed Apr 2 07:33:59 2025, Michael, Alex, General, Beam gone again
|
7:29, beam gone again, operators say they need another 5 minutes. |
|
Wed Apr 2 07:39:41 2025, Michael, Alex, General, The beam is back at 07:35
|

|
Wed Apr 2 07:41:10 2025, Michael, Alex, General, Frequency shift in Schottky
|
After the beam was restored at 07:25, we think that the frequency peak in the 244 MHz RSA2 has jumped again (closer to the center).
Previous to that, during the longer break in the previous night, the peak jumped to higher frequencies. |
