Fri May 7 04:26:54 2021, Shahab, Runs, 245 MHz resonator extra 20dB gain off
|
| made sure that the extra 20dB amplifier is off. |

Fri May 7 04:01:51 2021, Shahab, Runs, Picture after scraping
|
this picture is after scraping by helmut, showing the 410 MHz detector, that is we would expect an isomer where the marker M1 is, i.e. at 2.2kHz on the
left side, which we unfortunately don’t see (yet). |

Fri May 7 03:46:58 2021, Liliana, Akash, Wolfram, Helmut, Shahab, General, Scraper settings
|
Scraper settings have been played around with to try and remove satellite lines...
Helmut has now set scraper id GE01DS_H at -45mm (in position)

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

|
Fri May 7 03:33:11 2021, Liliana, Akash, Wolfram, Helmut, Shahab, General, status
|
At the moment we see a second peak to the left of each intense line.
The distance between the main peak and the shadow is roughly the same for each peak.
This hints to a sharp fall in the isochronicity curve.

Fri May 7 01:49:03 2021, Rui-Jiu Chen, DAQ, Comparison of I_Raw/Q_Raw between different reference level
|
This is a comparison of I_Raw/Q_Raw between different reference level. The range of NTCAP ADC is only 2^15 bit. So signals (I_Raw and Q_Raw) should
not be outside ADC range. It is clear that there is not point outside the ADC range when using reference level -30dBm. |
|
Fri May 7 01:47:36 2021, Ragan, Rui-Jiu, DAQ, Change reference level to -30dBm
|
Reference Level: -30 dBm.
Start taking data.
|
|
Fri May 7 01:44:24 2021, Rui-Jiu Chen, DAQ, Change reference level to -40dBm
|
Reference Level: -40 dBm.
Start taking data.

|
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.

Thu May 6 23:06:18 2021, Rui-Jiu Chen, DAQ, Change reference level to -50dBm
|
Beam is secondary beam now. The intensity is lower. Change reference level to -50dBm.
Carrier frequency:245MHz
IQ rate(S/s): 20M.

Thu May 6 22:05:30 2021, Helmut, Accelerator, Beamline and ESR data sets for 72Ge setting
|
| parammodi exports, E-SIS = 441.0 MeV/u with Be-1840 mg/cm² target in, isoc. ESR, at least we see fragments |
|
Thu May 6 21:45:30 2021, Helmut, Detectors, beam position on TE5 grids
|
The two grids do not work very well, one x position is opposite to the other.
But at least a guidance for the future, this was good injection of 78Kr with a thick Be target. |

NTCAP was stopped at 17:34 for the optimisation purpose.
NTCAP started again at 18:20 with the change in Reference Level (dBm): 0
