 Fri Jun 6 16:49:59 2025, CB, AY, ST, Beam overlap results for 200keV and 250keV 
|
For 200keV the optimal horizontal position is -5mm.
For 250keV the optimal horizontal position is -2mm.
Both values are already given to the operators, so tomorrow we can just switch to 200keV and go on :) |

Thu Jun 5 16:54:18 2025, EW, ST, CB, Run 52 - 0.3 MeV/A 14x
|
Run 52 started at 17:53. Everything is running again. We started at 3E12 at/cm2
D+ beam deuterium target. D+ beam energy is now 0.3 MeV/u. (beam calc calculation is 0.3067 MeV/u).
All four detectors positioned fully out and stationary and also detector #4 is running again. |

Thu Jun 5 08:50:00 2025, JM, CF, CB, EW, Run 51 - background
|
09:49
DSSD4 has been biased to 100V in steps of 5V from 60V. It was previously stable overnight at 60V - attachment 1
Will keep an eye on it but looks OK at the moment. Current bias and leakage current - attachment 2 |

|
Run 47 started. Target cooling down after water cooler failure, beam only background

|
Run 45 started.
D+ beam deuterium target. D+ beam energy is 0.5 MeV/u. (beam calc calculation is 0.5143 MeV/u). See attachment for beamCalc
Target density is about 2e12 at/cm2 |
|
Mon Jun 2 17:48:07 2025, JG, AG, Run 44 scraper tests
|
Same settings are Run 43 but with coasting beam and scrapers set to: 30 / - 30 mm.
all checks ok, but WR timestamp error, see attached |
|
Mon Jun 2 17:25:31 2025, JG, AG, Run 43 scraper tests
|
Same settings are Run 42 but bunched beam and scrapers set to: 30 / - 30 mm.
|
|
Mon Jun 2 16:35:35 2025, EW, AG, Run 42 and scraper tests
|
17:00
Scraper tests conducted. We tried moving in the scrapers both at a fixed position throughout and also moving with the injection cycle.
We were unable to find a good position with the scrapers that did not produce significant scattering in the detectors. |
