Laszlo | General | 2nd storage of MCP data | |
I made a backup for the MCP data on my own GSI laptop. Looking for better solution...

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 |

Closing file at 17:39, stopping data taking. Yuri will switch to primary beam through FRS without target.
Also a minor observation is, that at the end of the target on phase, the X-ray count rate is going up very high. (Data acquisition was in Jet Off mode)

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.
We are hoping for increased intensity and stable gas target.
The plan is to make a measurement with and without the scraper in order to see the effect of scraping the Rutherford scattering. |

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.
Now i can see peaks both at the 35 and 90 angle Xray spectra but not much on the 145 one.
At the end the target density stayed at 8.6E13. |

The beam is still unchanged. We just start a run to collect all remaining data.
Data is probably scratch, expect changing conditions at the machines during the run.
No counts in Target ON phase at Silicon Detector. Probably we had only two first shoots from FRS in this run (see picture below)
