Esther | DAQ | NTCAP off, RSA triggers disconnected |
The NTCAP computer and crate are switched off.
The triggers are disconnected from the RSAs, but they remain on. |

Yuri, Sergey, Nikos, Esther | General | Final Injection |
The a final injection from SIS18 stored at 10:04.
The scrapers were moved out before to get the maximum intensity.
NTCAP is still running, the RSAs recorded the last files at 10:04.
The plan is to keep running like this for about an hour. |

Yuri | General | Slit changing |
I would like to close E01 slits a bit more and get 30 min of data with higher
resolving power.
EEX scraper from -10 now -1

Esther, Nikos | General | Brief beam interruptions |
There was no beam from SIS between about 06:28 and 06:39.
Again from 07:02 to 07:11.
And again from 07:49 to 07:55. |

Sergey, Yuri and Xinliang | General | Move of the scraper positions at ESR |
From roughly … to 0:05AM, Sergey moved GEEXDS1HA (not
changed
in the end) and GE01DS3HG (changed from -85 to -80 mm) to reduce
the acceptance of the ESR to improve the mass resolution.
After the change, there are less small traces appearing in the
413.55735 MHz +/-5 kHz range.
The final positions of the two scrapers are
GEEXDS1HA :-10 mm; GE01DS3HG:-80 mm. |

Sergey Litvinov, Xinliang Yan | General | Tuning of the ion optics |
From roughly 10:45 pm to 11:05 pm, Sergey tuned the
ion optics of the ESR to see if the mass resolution at
413.55735 MHz improves or not. Please note that the
frequencies of ions during the tuning process are not
stable.
Q-magnets and S-magnets have been adjusted, see
accelerator E-logs ID-844 titled ‘ ESR seting for
204Pt77+’ created by Sergey. |

siddharth | Analysis | Sigma vs Mean Freq. Plot for 188Hf72+ setting 2 |
This is sigma vs Freq plot for 188Hf72+ made out of 1hr of injections post Saturday, April 5th.
The 2nd photo Compares the resolution of 188Hf setting by looking at peaks of 205Au and 205Pb which are very close in frequency range. The resolution in the second 188Hf72+ setting(on Right) seems much better as two peaks can be seen clearly. |
