Experts working on problem. Update at 14:00 18 July 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 17 July 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 17 July 2019 00:42 Beam ON at 00:45hrs 17/07/2019 16 July 2019 23:42 A water flow meter has been replaced and we have nearly finished running the Main magnet back up. Beam expected within 20 minutes. 16 July 2019 22:37 Currently investigating a problem with Main Magnet water flow. Update at 23:30 16 July 2019 11:47 Attention Methane Users: The Methane Moderator is now stable and operational. 16 July 2019 08:27 Attention TS1 Methane users: The Methane Moderator has become unstable again and requires a warm up to restore the stability and reduce the differential pressure in the moderator head. TS1 staff are scheduled to carry out a short warm up of the moderator starting at 09:00 this morning. Then after re-cooling, the moderator should be ready to use by Noon today. The beam will be left ON throughout this process, so other users should not be affected. If anybody has a strong objection to the start time of 09:00, it may be possible to delay the warm up slightly (by a maximum of 2 hours) – please call David Haynes on 1730 (short code) or 07770858056 to discuss further. 15 July 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 14 July 2019 08:41 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 13 July 2019 17:24 Beam back on to TGT1 at 17:15 13 July 2019 16:57 Beam to TGT1 will resume at 17:00. Although at lower levels to start with gradually increasing over 15-20 mins to ensure system stabilise. 13 July 2019 15:29 Experts have fixed the issue with the CH4 moderator. The system is now cooling down nicely. Beam will resume to TGT1 at approximately 17:00 13 July 2019 14:45 Experts are still in TSA1 working on the issue. Update in an hour 13 July 2019 13:44 Experts are currently in TSA1 working at issue. Beam to TGT1 should resume within the hour. 13 July 2019 11:25 There has been an slight issue with the Methane moderator cool down. Beam to TGT1 will have to be turned off at 11:30 for approxiately 2-3 hours. Beam will continue on TGT2. Update @ 13:30 13 July 2019 07:44 Attention TS1 methane users: Just a reminder the Methane moderator will be warmed up this morning starting at 08:30 and then re-cooled. The beam will be left on throughout the process so other users should not be affected. 12 July 2019 20:56 Beam ON 12 July 2019 20:49 Beam OFF - While we investigate a fire alarm in R5.1. 12 July 2019 16:37 Attention TS1 methane users: The methane moderator has become unstable again and requires a short warm up to restore the stability and reduce the differential pressure in the moderator head. TS1 staff are scheduled to carry out a short warm up of the moderator starting at 08:30 on Saturday morning 13.7.19 and then re-cooling to be ready for use by 12:30 the same day. The beam will be left on throughout the process so other users should not be affected. 12 July 2019 08:41 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 11 July 2019 17:13 Beam ON to both targets 11 July 2019 16:43 Beam OFF - Beam off to TS1 while we reconfigure to both targets. 11 July 2019 16:13 Beam OFF - TS2 is nearly cold and We shall start running beam to TS2 at 16:30hrs. 11 July 2019 14:52 The H2 system on TGT2 is cooling down nicely and will be ready by 16:00 Update @ 16:00 11 July 2019 11:54 The CH4 system on TGT1 has now cooled back down and is ready for use. The H2 system on TGT2 cool down is not going quiet as well, experts estimate it wont be ready until 15:00-16:00 Update @ 15:00 regarding progress on TGT2 11 July 2019 09:30 Experts estimate TGT2 H2 system and TGT1 CH4 sytems will cooled down and useable around 12:30-13:30. 11 July 2019 08:59 Now running to TGT1 only. Also reminder for TGT1 Methane users, the system is currently warming up. 11 July 2019 08:40 There is an issue with the compressed air system on TGT2, this may take 1-2 hours to fix. TGT1 only running while issue is fixed. Update @ 09:30 10 July 2019 17:59 The Methane system warm up on TS1 will commence tomorrow morning 11/07/2019 08:30hrs. This will take approximately 4 hours and we intend to leave the beam ON during the warm up so other users remain unaffected. 10 July 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 09 July 2019 17:42 Attention TS1 Methane Users: The methane system on TS1 has become unstable because we are nearing the end of the cycle and the moderator is blocking up. To try and stabilise the moderator until the end of the current user run TS1 staff would like to carry out a short warm-up starting from 08:30 on Thursday 11.7.19. The process should take about 4 hours in total and so we hope to have the moderator useable again by 12:30 on that day. If this timing is not convenient for anyone then please contact Dave Haynes to discuss. The intention is to leave the beam on throughout the process and so all other users should be unaffected. 09 July 2019 08:41 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 09 July 2019 05:45 Beam restored at 05:32. 09 July 2019 04:27 The kicker power supply requires changing. Equipment specialist is on route to site to assist. Update 05:30. 09 July 2019 04:13 03:35 Beam off. Vacuum pump on one of the accelerating cavities failed and has now been replaced. But one of the extract kicker magnet power suppilies has also tripped and will not come back on. We are now investigating this. Update 04:30 08 July 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 07 July 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 06 July 2019 22:41 Beam ON at 22:00hrs 06 July 2019 21:33 Beam OFF - Experts are still working on the cause of the EVB2 trips, update at 22:30hrs 06 July 2019 20:53 Beam OFF - EVB2 has tripped off again and experts are continuing their investigations. Update in 30 minutes 06 July 2019 20:22 Beam ON at 20:25hrs. 06 July 2019 20:07 Beam OFF - Investigations into EVB2 are still underway.

Update at 20:00 Hours. 06 July 2019 18:06 Equipment experts are in attendance investigating the fault on EVB2 power supply. Update at 19:00 Hours 06 July 2019 17:22 We have been unable to get EVB2 magnet power supply to it's operational current without further trips. An equipment expert is on his way to site to investigate. Update at 18:00 Hours. 06 July 2019 17:04 The machine is off due to an EPB1 power supply trip. The Injection Dipole power supply has also tripped with a large vacuum rise. We are attempting to get the equipment back on. 06 July 2019 12:23 Fire Bell testing in R80 has now finished. Please treat any further alarms as a real incident.
