21 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 20 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 19 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 19 February 2019 04:56 Machine Status: TS1 Beam Current: 175.6µA at 40.0Hz MUON Beam Current: 7.0µA at 40.0Hz TS2 Beam Current: 40.0µA at 10.0Hz TS1 Methane Temperature: 109.0K TS1 Hydrogen Temperature: 23.9K TS1 Muon Kicker: On TS2 Decoupled Methane Temperature: 45.9K TS2 Coupled Methane Temperature: 36.0K TS2 Coupled Hydrogen Temperature: 16.7K 18 February 2019 18:38 Please take extra care whilst travelling around the RAL site, as we have had reports that some of the street lights are not working. Every effort will be made to rectify the lighting issue as quickly as possible. 18 February 2019 14:13 Beam on 14:11 18 February 2019 14:06 Controls issue appears to be resolved now but one of the magnet power supplies has failed. A module in the supply is being replaced and should be up and running very shortly. Update at 14:30 18 February 2019 13:36 We are making progress with the controls issue and system specialists are currently working on a solution. Update 14:00 18 February 2019 13:00 Still investigating controls problem. Update 13:30 18 February 2019 12:31 The Beam Compensation unit has been replaced but unfortunately the controls has now stopped responding. This is being investigated and once fixed we will test the RF system. Update 13:00 18 February 2019 11:54 Beam Off 11:30 One of the RF systems beam compensation modules has failed. We require to access the inner synchrotron to replace this. Estimated time of 30 minutes. Update at 12:30. 18 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 17 February 2019 19:38 TS1 H2 moderator users: Moderator is now cooled to 16.9K and is ready to use. 17 February 2019 17:44 TS1 H2 moderator users: Target experts are still on site dealing with the moderator cooling. It is still cooling the circuit but they are going to adjust some parameters to try to get it down to temperature. Update at 19:30. 17 February 2019 14:59 Beam ON 17 February 2019 14:28 We have established beam at lower rep rates to target 1. We will try to reach full beam current by 15:00 hrs. Target experts estimate that the hydrogen moderator will be ready at 18:00 hrs this evening. We are still running full beam current to target 2. 17 February 2019 13:42 Beam to TS1 will be delayed slightly due to the H2 moderator cold box differential pressure. Target experts are currently waiting for it to settle down before receiving any beam. Beam is still on to TS2 at 40uA. Update at 14:45. 17 February 2019 12:33 We will be shortly locking up TSA1 and switching machine modes to both targets. This will mean a short beam off while we safely switch. This will be within the next hour. Update at 13:30. 17 February 2019 12:27 The IOn source change has been successful and the crew have aligned beam through the LINAC. Beam on to TS2 only. 17 February 2019 09:20 Beam is currently off for an ION source change. This was started at 08:45 and usually takes a minimum of 3 hours. Update at 11:45. 17 February 2019 09:13 TEST 17 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 16 February 2019 16:55 Unfortunately repairs on the H2 circulator have not been successful. We will need to gain entry to TSA1 and replace the faulty equipment. Best diagnosis for beam to TS1 will be 12:00 lunchtime 17/02/19. In 5 minutes, we will momentarily switch beam off to both targets in order to switch modes to TS2 running only. After that we will continue to run to TS2 only. 16 February 2019 14:04 Experts have recovered TS1 H2 moderator although it will take approximately 4 hours to cool down. We are currently switching back to running beam to both targets. Any instruments in TS1 using the H2 moderator: The moderator should be back down to temperature at 18:00. 16 February 2019 12:27 Target experts are on site trying to recover H2 moderator. Update at 14:00hrs. 16 February 2019 12:09 Beam On to TS2 only 16 February 2019 12:00 Beam off to enable switching to TS2 only running mode. 16 February 2019 11:51 Beam off to TS1. We have a problem with the H2 moderator. Expert on route to site. Update at 12:30. 16 February 2019 09:42 Beam ON 16 February 2019 09:11 We are experiencing problems with a target 2 water cooling circuit. Experts have been contacted for advice. Update at 09:45. 16 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 15 February 2019 22:38 Beam ON 15 February 2019 22:20 We are replacing the unserviceable power supply and hope to restore beam soon. 15 February 2019 22:05 We are contacting a member of Electrical Engineering Group for assistance with E2Q11 power supply. 15 February 2019 21:49 Beam is off whilst we investigate a fault with an EPB2 power supply E2Q11 15 February 2019 12:22 TS1 Hydrogen moderator is now cold and ready for use. 15 February 2019 11:31 BEAM ON to both targets 15 February 2019 11:31 BEAM ON to both targets 15 February 2019 11:04 EPB1 diagnostics problem has returned. Experts are narrowing down the fault and hope to reload software as soon as possible. We are still beaming to TS2 although beam may be intermittent. Update at 12:00. 15 February 2019 10:16 Beam on to both targets 15 February 2019 09:35 We are experiencing problems with EPB1 diagnostics. An expert is in attendance. We are still beaming to TS2. Update at 10:00. 15 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 15 February 2019 06:42 MS beam is now anticipated to be restored to TS1 at about 07:00 this morning. Please be aware that the TS1 hydrogen moderator will not be usable until about Noon today. Beam to TS2 will be going off at about 06:55, whilst we change over the machine mode. 15 February 2019 05:41 Beam to TS2 will be off for a short time, whilst we change over machine mode (to TS2 running only). 15 February 2019 05:02 Beam will continue to TS2. However, beam to TS1 will stay disabled until the issue with the Hydrogen system has been resolved. Next up-date at 07:00hrs. 15 February 2019 04:34 The beam to TS1 has had to be disabled; this is due to a problem with the Hydrogen cryogenic system. Beam to TS2 is unaffected. Two equipment specialists are on their way to site. Next up-date at 05:00hrs. 14 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 13 February 2019 20:57 Beam ON 13 February 2019 17:46 Work on EHB3 is progressing well. We are currently replacing all four water manifolds which we believe were causing the power supply earth leakage trips. We hope to restore beam by 21:00 Hours. 13 February 2019 14:58 There is an Earth leakage problem on one of the magnets in the Synch. Early estimate of Beam on is 21:00 13 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 12 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 11 February 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 11 February 2019 03:45 The beam has been turned off to allow us to repair a fault on the Prisma beamline shutter. This work should only take approximately 10 minutes. 10 February 2019 20:21 MS beam restored to both targets at 20:19hrs. 10 February 2019 20:06 A vacuum pump has failed in the Linac; a vacuum engineer is currently changing the pump. Update at 20:30hrs. 10 February 2019 19:15
