Keerthi | Other | General | MCIS turbo pump | MCIS TP1 is not running well. Needs investigation 
as soon as S1219 is completed.

be a marathon. Main goals are high-charge

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 |

Damien Gallop |   |   | MWS 25Mg beam reduction | Around noon, Keerthi adjusted the PE down 
to reduce the intensity of the Mg beam, as 
we are running with attenuators in. He ended |

Damien Gallop |   |   | MWS operation overnight and 25Mg status | So... there evidently was a power bump

I did a few mass scans to get a fix on Mg |
