27 July 2024 03:04 Machine update:- MS beam restored to both Target stations. 27 July 2024 02:14 Beam off We are currently working on a fault with one of the trim quad power supplies in the inner. Update in 30 minutes. 26 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 25 July 2024 18:27 Message from experimental controls group: The accelerator networking issue affecting beam status PVs has now been resolved and the beam status information in seci/ibex should now be working again. 25 July 2024 18:04 We are still having some issues with the control system. We have just reset a server which is gradually coming back online. We have just got the beam back to targets. Please give the servers time to fully reset before reporting any beamline issues. If you are still having issues seeing beam after 19:00hrs, let your beamline scientist or the MCR know. 25 July 2024 14:13 All equipment is on and we are running a base rate beam to carry out some machine set up. We anticipate running full rep rate beam to both targets shortly. 25 July 2024 12:40 The controls system is operational. However, we still have comms errors which are preventing us from running up equipment. Update at 14:00 Hours. 25 July 2024 11:33 The Controls team have made some good progress tracking the cause of the Network Issues. They think the problem is in the Injector area and are investigating further. Update in 1 Hour 25 July 2024 08:36 Our Controls and IT specialists are still looking into the Network issues. We are still unable to run beam. Once we have more information we will provide another update. 25 July 2024 05:02 Beam OFF - We are still experiencing on going issues with networks around ISIS. This is preventing us from beaming as we have no way of monitoring or controlling the machine. The controls group are working on the issue and we will issue an update later this morning. 25 July 2024 03:11 Beam off as we investigate issues with network 24 July 2024 08:46 Machine update:- ISIS maintenance day has now started after the data retrieval and work can commence. 24 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 24 July 2024 08:33 Machine update:- ISIS maintenance day started at 08:30hrs and will be for the next 24hrs. There will be a short duration of running this morning at base rate for essential machine data recovery. 23 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 22 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 21 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 20 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 19 July 2024 23:57 We are back on at full beam current to TS2. We are on a a lower rep rate to TS1 due to losses that are higher than we would like. We have a machine physicist on the phone who will tune the machine from home. 19 July 2024 22:18 We have rectified the fault with the TS2 cooling system. Unfortunately, we are now having issues with the control system for the whole machine. An expert has been contacted and they are working on the fault from home. Update at 23:30. 19 July 2024 21:06 We have a problem with the target cooling circuit in TS2. An expert is on their way to site. We have reconfigured the machine to TS1 only. Update at 23:00. 19 July 2024 11:45 BEAM ON - PLC issue resolved - Beam ON to both targets. 19 July 2024 11:25 BEAM OFF - The decision has been made to change modes and run to TS2 only whilst the TS1 PLC issue is resolved. 19 July 2024 11:15 BEAM OFF - We currently have an issue with the TS1 water PLC - Experts investigating - Update at 11:45 19 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 18 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 18 July 2024 02:15 Beam restored to Target 1 18 July 2024 01:03 Beam to Target 1 has been temporarily inhibited. We have an issue with both stack monitor readings which are high due to a fan tripping off. Once the levels have dropped below trip we will be able to restore beam. 17 July 2024 18:57 Machine update:- Beam restored to both Target Stations. 17 July 2024 18:20 Machine update:- Beam restored to Target 1 only. 17 July 2024 18:14 Machine update:- We have a problem with a flow sensor on Target 2 cooling circuit. Experts are on route to the facility to investigate this fault. We will be changing modes to Target 1 only whilst this fault is rectified. 17 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 16 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 15 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 14 July 2024 10:15 RIKEN is cleared for beam. 14 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 13 July 2024 21:21 Beam ON to both targets 13 July 2024 19:53 We have had a fault with some ventilation in TSA1. We have been in contact with experts and are in the process of remedying the fault. Update at 21:00hrs. 13 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 12 July 2024 19:05 Beam off to TS1 - The PLC issue has now been fixed and interlocks restored. We are in the process of searching the target services area. Once this is searched we can perform a mode change and restore beam to TS1. Beam should be restored at approximately 19:30. 12 July 2024 18:08 Beam off to TS1 - The target 1 interlock issue has been traced to a PLC fault which an expert is attempting to fix. Update @ 19:00. 12 July 2024 17:10 Beam off to TS1 - Equipment experts are on route to site to investigate the cause of the interlock failure. Update @ 18:00. 12 July 2024 16:26 Beam off to TS1 - We have experienced an issue with Target 1 PPS interlocks and are in contact with equipment experts to diagnose the cause of this issue. We have changed modes to run to TS2 only. Update @ 17:00. 12 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 11 July 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 10 July 2024 22:11 TS2 Beam restored 10 July 2024 22:04 We are running equipment up and hope to restore beam to TS2 soon. 10 July 2024 19:26 Further to the last message: Target Station 2 Engineers have requested access to the TS2 Target Services Area to survey the Atex room. The extract from this area is vented through the Stack counter which is giving us high readings and inhibiting beam. Access can't be made before 20:50 Hours and they will need at least an hour in the area. We will give an update on progress at 22:00 Hours 10 July 2024 18:59 Beam to TS2 has been temporarily disabled. There is an ongoing issue with a Discharge Stack monitor which inhibits beam. The trip level is higher than the last one so it may take in excess of an hour before the count is at a level where we can reset and restore beam. 10 July 2024 17:01 Beam restored to TS2 10 July 2024 16:39 Beam to TS2 has been temporarily disabled. There is an issue with a Discharge Stack monitor which inhibits beam. We expect to be able to reset within an Hour and will restore beam ASAP. 10 July 2024 15:15 Beam ON. The power supply has been repaired and we are back running full rep rate beam to both targets. 10 July 2024 10:39 The repair will now begin at 13:00hrs to accommodate experiments. 10 July 2024 10:16 IHVD1 HEDS power supply has an over heating connection that requires replacement. This work is expected to take 2 hours. We plan to turn the beam off at 12:00 hours today to repair the supply. Please contact the Main Control Room on 01235 446789 if this time is particularly
