5 | This list is for tracking the state between BLOCs, and should be viewed before an expert is called. This is complementary to the whiteboard in the control room. |

7 | h2. Access / Construction Work |
||
8 | |||
9 | * Hall is open. |
||
10 | * PRY construction continues - hence crane activity |

22 | h2. Systems |
||
23 | |||
24 | * Beamline: |
||
25 | ** The beamline polarity is set to mixed polarity |
||
26 | ** Control boards have been swapped between Q4 and Q5 MPS to look into ramping issue. |
||
27 | * DS: |
||
28 | ** The Linde Fridge is running |
||
29 | ** The PSU is isolated from the DS, and undergoing testing to look for overtemperature trips. |
||
30 | *** If it trips, leave as-is (do NOT reset interlocks) so that the specific channel can be identified |
||
31 | * Proton Absorber: |
||
32 | ** need to further close damping valves |
||
33 | * Beamstop: |
||
34 | ** Powerpack 2 has a cracked hose fitting awaiting replacement and is out of use |
||
35 | * MLCR: |
