Damien Gallop | | | MWS 25Mg end of run data | Marco gave us the all-clear this morning
to shut down the MWS. We are preparing to

Damien Gallop | | | MWS 25Mg operation overnight & MCIS cart installation | As noted earlier, the MWS beam dropped
out at some point after yesterday afternoon's
playtime, due to insufficient PE. Plasma |

Damien Gallop | | | MWS source trip & restart | Well, so it goes. As I was penning a note
for OPS, the source tripped. It easily reignited
with a little extra Ne. I left the flow slightly |

with intense Mg beam coating our optics.
Keerthi found a good recipe last week with |

with a little 25Mg beam on FC6. This morning
I did a few mass scans to get a fix on Mg |
