 Sat Mar 21 13:24:10 2020, Laszlo, Runs, run entry - run063,
|
open file : run063
beam: 118Te52+
|
|
Sat Mar 21 13:37:53 2020, Laszlo, , MCP can monitor target,
|
now with the MCP we can see clearly the effect of the target :) (scintillation?)
so we want to scan through the target thickness with the beam and choose the best position afterwards.
|
Sat Mar 21 14:52:05 2020, Laszlo, General, target optimization, 
|
previous position of the beam at target was -3mm (for the night position)
max. intensity position of the beam at target 1s -1mm. --> now it is set to this position
|
|
Sat Mar 21 15:26:49 2020, Laszlo, General, SCRAPER is ON use again,
|
| Yuri puts back the scraper (Egelhof 1 - GE01DD1IG) into position = +19. (where it was in the evening) |
|
Sat Mar 21 17:21:57 2020, Laszlo, General, new Target density,
|
Ulli and Nikos managed to set the target density to ~7E13 at 51K temperature
The cycle is checked again, it seems fine. |
|
Sat Mar 21 23:07:00 2020, Laszlo, General, 1672. MCP file was (recoils) was not closed,
|
1672. MCP file was (recoils) was not closed when we refilled the Xrays and did the cable change of 90 and 145 xrays
These stored in lxg1299 local disk |
|
Sun Mar 22 12:53:43 2020, Laszlo, General, quick summary for the 118Te overnight measurement,
|
Quoting Yury:
"The count rate is very low. We estimate that we store about 10^4 118Te particles at 10 AMeV. This is a very low number.
On Saturday we re-implemented the recoil setup (MCP from Pierre-Michelle) from the previous experiment and could verify the overlap between the stored |
|
Sun Mar 22 13:33:19 2020, Laszlo, General, 2nd storage of MCP data,
|
I made a backup for the MCP data on my own GSI laptop. Looking for better solution...
the original "fresh" files stored at litv-exp@lxg1299:/data.local2/hillenbrand/Laszlo/ |
|
Sun Mar 22 14:58:59 2020, Laszlo, General, dropping density of Gasjet,
|
after like 20min run, the density of the gasjet already dropped from 10^14 to 8.7*10^13. Now it seems to remain in that value
Below in arbitrary units one can see the trend of the gas jet density starting from 10^14 to 8.7*10^13 |
|
Sun Mar 22 17:45:07 2020, Laszlo, General, switching to primary beam,
|
We have finished the measurement with the fragments.
Now Yury will setup up a primary beam through the FRS, but without target in FRS.
|
|
Sun Mar 22 17:47:27 2020, Laszlo, , Si, Xrays target density spectra during 118Te afternoon measurement,
|
We got 30 counts out of this afternoon 118Te run on our Si TargetON histo.
That 1 count at bin (6,10) I dont understand.
|
|
Sun Mar 22 18:35:43 2020, Laszlo, , target dropped aagain,
|
| there was a drop again from 8.6e13 to 7e13 in the target density |
|
Sun Mar 22 19:15:03 2020, Laszlo, , Si moved out of the ring, high voltage is switched off,
|
| |
|
Mon Mar 23 00:13:25 2020, Laszlo, General, SIS and ESR beam currents,
|
| |
|
Mon Mar 23 07:56:51 2020, Laszlo, General, Yuri made magick and we operate again,
|
DSSSD was moved out (HV switched off)
also the scraper was mistakenly moved.

|
Mon Mar 23 09:33:11 2020, Laszlo, General, SIS failure again!,
|
| run096 is stopped |
|
Mon Mar 23 09:47:05 2020, Laszlo, General, explanation of an ESR cycle,

|
Mon Mar 23 10:06:12 2020, Laszlo, Runs, run entry - run097,
|
| this one is garbage |
|
Mon Mar 23 11:32:42 2020, Laszlo, General, SIS went down again,
|
| run101 is stopped |

Mon Mar 23 15:48:15 2020, Laszlo, Calibration, run105 - Xray90 calib Am241, distance 167.5mm, wrong?,
