12 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 11 May 2024 13:19 Machine update:- Unfortunately the warm up and cool down of the Hydrogen system on Target 1 overnight has not cleared the contamination in the system. The only thing we can do now is a complete warm up, blow the system through and then cool down again. This process is estimated to take 48 hrs at the earliest. Therefore no beam is expected to Target 1 before Monday evening. 11 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 11 May 2024 00:55 All TS2 instruments should be working. If you are still vetoing or have any further problems, please call the MCR. 10 May 2024 23:25 We are aware multiple TS2 instruments are vetoing. Controls are currently looking into the problem. 10 May 2024 20:41 TS2 users only: Machine setup continues. We have successfully transported beam down the Linac. We are now trying to get it going around the synchrotron nicely before we move onto alignment of EPB2. 10 May 2024 18:23 Machine update:- The Target 1 Hydrogen system has contamination due to the beam off time. As a result it now needs to be warmed up and re-cooled down, this process will take approximately 24 hours. We have changed modes to beam to target 2 only whilst the cryogenic fault is rectified and will be starting machine setup very soon. Further updates will follow. 10 May 2024 17:30 Machine update:- A lot of the equipment is now operational and back at standard settings to run. We still have a problem with Target 1 and will require a further few hours to monitor the cryogenic systems. Hopefully we will be starting machine setup within the next 30 minutes. Updates will follow. 10 May 2024 13:21 Machine update:- We have suffered a major power outage which has tripped a lot of equipment. Unfortunately this will take some time to recover from. Updates will follow. 10 May 2024 12:23 Machine update:- We have an engineer looking at the shutter jack on top of the target station, hopefully beam will be restored momentarily. 10 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 09 May 2024 13:51 Machine update:- Beam restored to both Target stations at 13:45hrs. 09 May 2024 13:19 Update: The MMPS fault has now been rectified and MMPS run up to operating current. We now have a fault on one of the EPB2 Quads - we are in the process of swapping this over for a spare. Update at 13:45 09 May 2024 12:22 BEAM OFF - The MMPS DC has tripped off. We are currently investigating the cause of the trip. Update at 13:00 09 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 08 May 2024 23:29 Beam restored to both Target Stations 08 May 2024 22:39 Beam OFF - experts are still working on the kicker supply. Update at 00:00hrs. 08 May 2024 20:30 Beam OFF - We have a issue with Kicker 3 power supply. experts are on the way to investigate. Update in 1 hour. 08 May 2024 14:42 The extract kicker fault has been rectified. We are currently on to TS2 at base rate doing some machine set-up. Machine rep rate will be increased when possible. TS1 users - The H2 moderator cooldown has gone well and they are currently transitioning to liquid. If there are no further problems they will be ready for beam in approximately 3 hours. 08 May 2024 13:42 We are currently experiencing a fault with the extract kicker supplies. Experts are in attendance. Update at 14:30. 08 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 07 May 2024 10:15 After last nights warm up of the H2 moderator target staff found the helium cold box contaminated. This will require a purge before trying to cool back down again. Staff have started work on this and all going well a cool down will be started tomorrow morning with the moderator ready to use tomorrow afternoon/early evening. Please be reminded that a maintenance day will take place tomorrow with beam going off at 08:30. 07 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 06 May 2024 22:22 The cool down on Target 1 H2 moderator has failed and experts are going to warm up the system overnight and investigate the cause of the failed cool down tomorrow morning. Therefore, there will be no beam to TS1 until at least tomorrow evening. An update on progress will be issued tomorrow morning. 06 May 2024 19:01 TS1 users: Experts are still working on cooling the H2 moderator. They estimate that they will be ready in 2-3 hours. Update at 22:00hrs. 06 May 2024 15:06 We have beam back on to TS2. TS1 users: The H2 moderator is being cooled back down. Experts have been on site for the last few hours. Its probably in the region of four hours from this point before we can beam to TS1. Update at 19:00hrs. 06 May 2024 13:02 Plant staff have made a repair on the water pipe that had split. We are just in the process of trying to get all equipment back operational. Update at 15:00. 06 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 06 May 2024 08:18 We have suffered a split in a main chilled water pipe from R4 plant area. Plant staff are already trying to implement a repair. This water supplies most of the equipment on ISIS so we have had to switch a lot of equipment off. At this point its hard to determine an estimate for beam off time but it will be most of the day today at least. Update at 13:00. 06 May 2024 04:50 We have reset the extract septum but are experiencing high beamloss around injection. Investigations underway. Update in 30 mins. 06 May 2024 02:56 The injection septum magnet has tripped on magnet water flow. This requires access to the inner to adjust before restarting the power supply. Update in 30 minutes. 05 May 2024 22:51 Beam ON 05 May 2024 22:35 Beam OFF - Kicker 2 magnet has tripped off and requires resetting. Update in 20 minutes. 05 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 04 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 03 May 2024 17:01 Beam ON 03 May 2024 16:29 Ion source experts have replaced a failed H2 control crate and will now attempt to run-up the ion source. Update @ 17:30. 03 May 2024 15:38 BEAM OFF - We are experiencing an issue with the ion source. Experts are investigating the cause of the problem. Update @ 16:30. 03 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 02 May 2024 15:32 Beam ON 02 May 2024 14:34 A new Ion source has been successfully put in and run up. We are currently in the process of running up the Linac. After that we will need to do a beam alignment. Update at 15:30. 02 May 2024 13:10 Upon start up the new ion source developed a fault meaning we will have to change it again. Update at 14:30. 02 May 2024 09:03 The Ion source is running out of caesium and will require changing. We have made efforts over the last couple of days to make it last until maintenance day but this morning it has reduced in output. We have made the decision to change it. Beam will be switched off at 10:30 am and will be off for approximately 3 hours. We will update as work progresses. 02 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 01 May 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 30 April 2024 09:19 Beam ON 30 April 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 30 April 2024 08:24 Beam OFF - We need to access the Ion source area to make some adjustments. This work is expected to take approximately 30 minutes. 29 April 2024 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 28 April 2024 15:34 Beam ON 28 April 2024 14:59 TS1 update: The methane moderator is in the final stages of cool down. Target experts are still on site and checking that the moderator parameters are behaving as expected. Barring any further problems, we expect cool down to be complete in the next hour. Update at 16:00. 28 April 2024 12:20 TS1 update: Target staff had problems within the methane system initially which meant a slight warm up was required. They will shortly start to cool
