 Sun May 9 23:24:49 2021, Helmut, Wolfram, Yuri, Accelerator, scraper optmisation for 72Ge
|
We tried the scrapers a bit, because right of peak some background appeared.
The GE01DS_HI shows a strange effect,

Fri May 7 03:44:55 2021, Helmut Weick, Accelerator, scraper optimisation
|
Opened TE4 slits again to +/-10mm.
Then we tried different scrapers:

Uc = 250mA

Sun May 9 19:03:02 2021, Rodostina, Oliver, Wolfram, Helmut, Yuri, Shahab, Runs, quadrupoles were down, fixed.

Thu Jul 1 18:49:59 2021, Shahab, Runs, possible isomer? 
|

|
Sun May 9 02:32:58 2021, Jacobus, Shahab, Runs, possible 52-Mn isomer
|
| the intensity of the line on the left side is so high, it is difficult to see the isomers in the middle as can be seen in the auto generated picture |
|
Fri May 7 03:51:56 2021, Shahab, Analysis, peak frequencies
|
| a reference schematic of the peaks on 410 MHz (211th harmonic) and 245 MHz (126th harmonic) |
|
Sun May 9 23:32:24 2021, Helmut, Accelerator, parammodi saves 8x
|
Here are parammodi saves for TE-line and ESR for all four fragment settings:
For the first run of 72Ge (7.May) I do not have files.

Sat May 8 21:08:13 2021, Helmut, Sergey, Shahab, Wolfram, Yuri, Accelerator, optimisation of sextuples
|
| The optimisation of sextuples is finished. Record a few files. |
|
Sun May 9 05:38:29 2021, Iris, Chris G., Analysis, offset btw png and tiq files from server?
|
This might have been answered before but I looked at one png file and one tiq file from the same run that was stored on the server. There seems to be an
offset of 2.2 s. The png file from the server (right) shows the injection at ~5s, whereas when I look at the tiq file in the GUI (left), the injection
is at ~2.8 s???? Is the looper introducing this offset? |
 Sun May 9 05:54:11 2021, Ragan, Analysis, offset btw png and tiq files from server?
|
| This is due to the 50% trigger setting in the spectrum analyzers )) |
|
Mon May 10 00:41:20 2021, Chris C, Accelerator, no beam
|
Beam gone ~0:34.
Working on getting it back.
Back in business ~0:57. |
|
Fri May 7 17:02:51 2021, Kanika, Sergey, Yuri, Wolfram, Michael, Shahab, Runs, new sextupole setting 2
|
| There is new sextupole settings, but the scrapers remain like last night (Helmut setting last night.) |
|
Fri May 7 16:17:21 2021, Sergey, Yuri, Wolfram, Shahab, Runs, new sextupole setting
|
| new sextupole setting, isomer not visible yet. |
|
Fri Jul 2 11:44:25 2021, Helmut, Yuri, Accelerator, move scrapers to see effect on unknown lines
|
We close the arc inside and straight section inside scrapers to narrow and cut the 70Se line.
Then look what the other lines left of 70Se will do.
|
|
Fri May 7 01:07:27 2021, Helmut Weick, Analysis, maybe frequency ID
|
We think we see the frequency range of A/q=2.25 at 243.1 MHz.
This would correspond to L=108.2m and E=386.4 MeV/u (gamma_t = 1.3955) at h = 126.
Path length is a bit short, for L=108.4m it should be 370.6 MeV/u.

Tue Jun 29 21:15:01 2021, Kanika, Shahab, Runs, lost beam problem Unilac
|
| cooling water in UNILAC is out |
|
Mon May 10 03:37:53 2021, Chris C, Analysis, isomer? or wishful thinking?
|
| They are not easy to find, but we do occasionally see what might be the isomer. |
