08 February 2023 21:56 Beam on 08 February 2023 21:51 Beam has been off whilst we accessed the Inner Synchrotron to address an issue with the RF systems. We are just bringing the machine back on. 08 February 2023 18:40 Beam on 08 February 2023 18:32 We have an issue with a Synchrotron extract kicker power supply which we are currently investigating. 08 February 2023 05:38 Beam ON 08 February 2023 05:26 We are experiencing a fault with one of the extract kicker power supplies and we are currently trying to resolve the problem. Update @ 06:00. 07 February 2023 08:29 User run started @ 08:30 05 February 2023 23:24 Further to the last message: The Ion source failed over the weekend and has been changed. The scheduled change on Monday morning will now NOT take place and the machine will continue to run to TS2. 05 February 2023 23:04 MS Beam to Target Station 2 has been established and will remain on. There may be some short duration interruptions whilst we reconfigure the machine mode. This is to enable further commissioning and setup of Target Station 1. 05 February 2023 12:01 The Following beam lines have been cleared for operation: ZOOM SANS2D 05 February 2023 10:43 Beam ON The Following beam lines have been cleared for operation: CHIPIR IMAT LET NIMROD 05 February 2023 10:31 Beam ON The Following beam lines have been cleared for operation: POLREF INTER OFFSPEC LARMOR WISH 20 December 2022 08:28 Repairs to Tank 3 window are complete and the Linac is now operational. Beam to TS1 has now finished. Beam to TS2 will be intermittent at base rate over the next couple of days whilst the machine physics schedule continues. 19 December 2022 06:14 Tank 3 window has been replaced and the vacuum is recovering. It is expected to take at least 12 hours before RF conditioning can begin. Update @ 18:00 19 December 2022 00:47 Linac experts have confirmed that Tank 3 window has failed. The window will now be replaced which should take around 3 hours to complete and then the tank vacuum can be recovered. Update @ 06:00 18 December 2022 23:17 We have a problem with Modulator 3 in the Linac. Experts have been contacted and are on route to the facility to assist with investigations. Update @ 00:30 16 December 2022 08:49 Apologies for any confusion with the last message. The user run has now ended and beam has finished for TS2 users. 16 December 2022 08:26 We have suffered a loss of synchrotron diagnostics forcing us to switch the beam off. Its unlikely that we will get beam back on before the end of the user run. After that there may be sporadic beam but it cant be guaranteed. 15 December 2022 15:53 Beam ON 15 December 2022 15:49 Beam OFF We are currently experiencing issues with the ION source. An expert is in attendance. Update at 16:30 15 December 2022 06:43 Beam ON 15 December 2022 05:02 Beam OFF - The flow meter has been repaired and all RF systems are operational. We currently have an issue with the control system that is preventing us from setting up beam, experts are on route to rectify this issue. Update at 06:00 hrs 15 December 2022 02:30 Beam OFF - The flow meter may require replacement. Experts are on they way in to carry out repairs. Update at 04:30 hrs 15 December 2022 02:12 Beam OFF - We have an issue with a water flow meter in the inner Synch that requires repair before we can continue running beam. Update at 03:00 hrs 15 December 2022 01:26 The Linac has been run up and we are carrying out alignment checks. Update at 02:00 hrs 15 December 2022 00:33 Correction - Update at 01:00hrs 15 December 2022 00:32 The Ion source has been replaced and is running ok. We are currently in the process of running the linac up before setting up beam. Update at 13:00hrs 14 December 2022 19:59 Machine Update:- The Ion source has failed, various attempts have been made to try and recover it, but unfortunately we are going to have to perform an Ion source change. This process will take several hours. Next update 22:00hrs 14 December 2022 11:40 At 12:30 this afternoon beam will be turned off to perform a mode change. This should take around ten minutes to complete. 14 December 2022 09:49 At 10:30 this morning beam will be turned off to perform a mode change. This should take around ten minutes to complete. 13 December 2022 14:38 The H2 moderator has now cooled down and is reading 19K. 13 December 2022 12:41 We have experienced a problem with the H2 moderator on Target 2 that has caused it to heat up slightly. The experts are aware but the moderator will take a few hours to cool down again. 13 December 2022 10:40 Beam ON 13 December 2022 10:08 We are experiencing a problem with a synchrotron vacuum gauge and experts are investigating. Update @11:00. 13 December 2022 06:02 Beam ON - Beam restored to TS2. 13 December 2022 05:18 The Tank 3 vacuum has reached 5.0e-6 and we have begum running a low rep rate beam to TS2. This will be increased as the vacuum level and beam loss allows. 13 December 2022 00:16 Tank 3 window conditioning has progressed well. The tank is currently running closed loop at full rep rate. The vacuum is 8.0e-6 and needs to reach 5.0e-6 before we attempt to run any beam. Update at 06:00hrs 12 December 2022 09:03 Tank 3 window has been replaced and we are now waiting for the vacuum to recover before the Tank RF conditioning can begin. Beam is not expected to be available before 06:00 tomorrow morning but updates will be made during this time. 12 December 2022 05:26 Machine update:- Experts have attended site and confirmed that the window in Tank 3 has failed. The window change is in progress and expected to take approximately 3 hours then additional pump down time. Update 09:00hrs. 12 December 2022 04:02 Machine update: We have a problem with Modulator 3 in the Injector, experts have been contacted and are on route to the facility to assist with investigations. Update @ 05:00hrs 11 December 2022 02:08 Machine update. We are still trying to rectify the problem with the Kicker power supplies. Next update @ 03:00hrs. 11 December 2022 01:27 Machine update. We have a problem with the Kicker power supplies in R4, we are in contact with experts to try and rectify the problem. Next update 02:00hrs 10 December 2022 16:20 Extremely successful testing of new Target 1 systems today. All systems remained very stable and performed well with the MS/4 34uA Beam. Reconfiguring of machine to Target 2 only at 17:00. 10 December 2022 10:09 Full Rep/rate Beam has now been restored to Target 2. 10 December 2022 09:42 Machine is running at a lower Rep/rate for the moment while physicist sets up beam to Target 1. Full Rep/rate Beam should return to Target 2 within 30 mins. Update @ 10:15 10 December 2022 08:10 Machine reconfiguring complete, Beam back on to Target 2. 10 December 2022 07:43 At 08:00 beam will be switch off for 15-30 minutes to reconfigure the machine to allow Beam to Target 1 and 2. 08 December 2022 09:06 Attention TS2 users: The Hydrogen moderator temperature has recovered below VETO. We are currently addressing an issue in the LINAC after which we will restore beam. 08 December 2022 09:05 Attention all ISIS Users: There will be coffee, cake and mince pies in TS2 foyer today at 3pm. Everyone welcome. 08 December 2022 07:28 TS2 Hydrogen Moderator has again increased in temperature above Veto at 26.5K. Beam will remain off whilst the system recovers.
