21:00
Claude has achieved optimal cooling parameters for the beam
No target and internal work inside the cave tomorrow is required |
|
Tue Jun 11 19:44:48 2024, OF, SS, Target out and at He
|
Target has been moved out and H2 switched off. Changed to He.
Nikos will repair nozzle tomorrow morning. Remote checks until then. |

Ion beam energy is calculated using Beamcalc (https://web-docs.gsi.de/~lestinsk/beamcalc/electron.php)
Electron current is set to 4.3 mA and can be taken from Grafana
Alpha factor is 50 |

Sun Jun 9 09:45:27 2024, JM, CB, Beam-Target Overlap
|
Target density this morning had stabalised at 7e11 at/cm2
This is sufficient to test the beam/target overlap using the lifetime of the beam in the ring.
Previous attempt at this method was done at 1.5e11 at/cm2 where lifetime from residual gas and target are essentially the same. |
