*DS Power Supply work
78
** (Trevor) The PS is expected to return in mid-February (8th - 15th). He plans to start commissioning
79
the new PS on Feb 22nd. This could roll into the next week (which is nominally a data-taking week so may need to be postponed).
80
** (Vicky) The compressor has a leak and will be fixed on Friday 29th and cleaned on Monday 1st
81
** (Discussion between Mike, Vicky and Henry) : The Linde IOC has been beahving oddly and we need to understand it.
82
*** *Action Item* : Paolo, Mike and Vicky will investigate this issue ASAP. We can't cool down magnet until this is understood.
83
** (Discussion between Mike, Vicky and Henry) : We plan to start the cooldown of the cold box on Tuesday 2nd, with work on the controls and
84
monitoring doable whilst that is happening. If all is well, we can start the cooldown of the magnet  on Thursday 4th.
85
** (Discussion between Paolo and Mike) : we need a way of monitoring the status of the Linde IOC machine
86
** *Action Item* : Paolo/Pierrick to consider this issue
87
 
88
* Controls and Monitoring : Network reconfiguration
89
** (Paolo) Most work has been done but we wait for Pierrick to return to finish it. There is potentially another week of work with 1 - 2
90
days of severe disruption to the network whilst things are tested. This needs to be advertised well in advance
91 1 Boyd, Steven
92 20 Boyd, Steven
* Realignment work
93
** Drilling of holes in the flanges will be done by Thursday 28th
94
** Template to show where the holes should go have been designed but need to be constructed.
95
** EMR will not be moved further at this time
96
** Revisit next week
97
98
* Tracker patch panel leak work
99
** John wants to take the front of the PRY off to get at the tracker leak, which he may have a solution for. This can be done now.
100
101
* DSA Work before closure on Friday 29th
102
** Need to reconnect the dipole magnets, and test all magnets in the DSA 
103
** New drip trays will not be installed at this point
104
105
* Electrical work schedule
106
** (Trevor) Trevor/Steve Griffiths will be here on Monday 1st/Tuesday 2nd to do a low current test on the SS. This will
107
require the Hall closed up and the SS permit to be granted. DC will work with Trevor on this.
108
*** *Action Item* : (John G) need to put barriers around any open part of the SS
109
*** *Action Item* : Andy/DC will organise the magnetic sweep
110
** A long discussion on the Daresbury scheduled ensued. We decided we needed a longer discussion.
111
** *Action Item* : Colin, Trevor, Steve, Pierrick to have a meeting to review the Daresbury work schedule in light of running time
112
and the currently known state of the SS work. Meeting to happen on morning of Thursday 28th.
