** Q4 was flushed and operated and maximum current. It didn't trip (which doesn't necessarily mean that the trip problem was fixed, just that we haven't harmed Q4).
41 10 Boyd, Steven
** Pierrick checked the temperature readout for Q5/6 which appears to be swapped. He believes that the problem is in the addressing, and
42 10 Boyd, Steven
this can be fixed in software. He's implemented a fix, but hasn't tested it yet.
43 10 Boyd, Steven
** Pierrick has written up a document for the changes to the network for C&M but has not distributed it yet. He thinks that the work will 
44 10 Boyd, Steven
take place from Jan 15th - Jan 31st.
45 10 Boyd, Steven
** John has already started flushing the other conventional magnets but has run into problems with air blocks in the line. He thinks he has
46 10 Boyd, Steven
a work around for this which he'll look at this week. 
47 10 Boyd, Steven
** Henry has come up with a design for the conventional magnet drip trays and will talk to John about it on Thursday.
48 10 Boyd, Steven
** Andy and John are on discussions about a way to make the top of the PRY safe. At present the idea is to install some mesh to
49 10 Boyd, Steven
stop people falling into the PRY from above with a N-S clip-on bridge, but this needs some development. Hope to have this in place by
50 10 Boyd, Steven
the end of the month. Josef has used a Scottish company which manufactures bespoke bridges like this and will talk to Andy.

54 10 Boyd, Steven
** The operations calendar has been updated with activities that are planned for this month.
55 10 Boyd, Steven
** There was discussion concerning whether SSD can be manually realigned before the Feb data-taking or between the Feb
56 10 Boyd, Steven
and April user cycles. It was clear that we wouldn't decide in this meeting

*** *Action Item* : Colin will organise a meeting for Thursday morning to consider this issue.
