David, Pierre-Michell | Update status | In this last hour we have been playing
with the cryostat temperature as dictated
by Nikos, in order to have the target working |

Sun Feb 27 00:07:15 2022 |
David, Pierre-Michell | No beam, valve closed | At 00:37 we lost the beam due to a high
pressure burst in the tarjet which resulted
in a valve closed at YR09VV... |

Sun Feb 27 00:53:24 2022 |
David, Pierre-Michell | Current status | We have recovered the beam at 01:49, after
such a long time we had no target so we increased
from 80K to 120K at 01:52. 02:01 update 120K-->95K |

Sun Feb 27 01:46:56 2022 |
David, Pierre-Michell | Current status | So far looks like with a temperature of
95K the target is maintained with a reasonable
density throughout long periods of time. |

Sun Feb 27 02:38:52 2022 |
David, Pierre-Michell | Current status | We have decreased the temperatur> 95K
--> 90K. At 95K the target was stable,
but let's try to increase the density |
