Sat Apr 4 17:32:01 2020, Ragan, Alex, Esther, General, No beam in ESR
|
The beam is coming from SIS but doesn't arrive in ESR because the quadrupole magnets in ESR have failed.
Update (18:01): Problem has been resolved. |

Sat Apr 4 18:57:49 2020, Ragan, Alex, Esther, General, Timing problem with SIS & ESR and problems with stacking
|
There are further problems with beam stacking in ESR. It works occasionally but keeps failing.
There is also timing problem between SIS and FRS. |

|
Sat Apr 4 22:31:02 2020, Alex, Esther, General, Beam in ESR lost
|
The beam in ESR was lost suddenly at ~22:20 due to a power supply failure of the quadrupoles.
Update (~20:40): Failure was resolved and new stacking started. |
