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. |

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.
Helmut now tries to remove these shadows by using different scrappers. |

Helmut Weick | Accelerator | scraper optimisation |
Opened TE4 slits again to +/-10mm.
Then we tried different scrapers:
in south arc outside: E02DS3HG, cuts at ~ -25mm, at -15mm gone, leave at -35mm.
on straight section: EEXDS2HA cuts at ~ -25mm, leave at -25mm.
EEXDS1HA, closing it to -25mm revealed a double peak structure with distance just like the wanted isomer (-2.2MHz at h=211).
But it is present on all intense peaks at the same distance, so it must be an artefact of a strange isochronicity curve.
Closing it to -15mm even had only the smaller lower frequency line survive.
But then it must be also possible to have only the stronger line. leave at -25mm
This worked with scraper in north arc E01DS_H which can cut from both sides.
The insie can ve iused to cut the lower Brho,
at -50mm still two peaks, at -45mm left peak almost gone, -40mm left peak gone but right still intense, leave at -40mm.
-> Lower Brho seems to be clearly related to lower frequency, higher Brho side is not so clearly related to frequency.
Measure in this setting, nice void at wanted frequency. But no isomers appear so far.

Helmut has now set scraper id GE01DS_H at -45mm (in position)

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). |

Xiangcheng suggested to change the trigger position in order to start the file with the injection. Nothing is changed at the moment. Maybe Shahab or Yuri can do it when they arrive. |
