There is now normal access to R6 areas. 01 April 2019 07:36 Beam to the Synchrotron Room Beam Dump will commence in one hour at 08:30 hours. This mode of operation may increase the risk of exposure to radiation to individuals in the R6 north 'Bat Cave'. In 15 minutes time at 07:45 hours, access to R6 north 'Bat Cave', tunnel 3 stairs to R6 and the Chalk Pits areas will be prohibited until further notice. Tensator 'No Entry' barriers and signage will be erected to indicate prohibited areas and names of individuals ignoring these barriers will be recorded. 31 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 30 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 29 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 29 March 2019 08:40 Machine update: We expect 40Hz beam to target 1 from midnight tonight to 8am Saturday morning. 29 March 2019 08:33 Machine update: User run 2018/04 finished at 08:30hrs. 28 March 2019 13:25 Fire alarm testing is scheduled to take place at the following locations at the following times. 13:45 R5.1, R5.2 & R5.5 14:00 R5.4 14:30 R55 15:00 R6 15:30 R80 16:00 R105 & 106 28 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 27 March 2019 17:40 Beam ON 27 March 2019 17:20 We are investigating a problem with the Ion Source. Update at 18:00 Hours 27 March 2019 12:05 Beam back on. Maybe slightly intermittent for next 30 minutes while it is optimised. 27 March 2019 11:35 Synch RF system is now fixed. Beam should be restored within the hour, few elements need to be run back up. Update @12:30 if not before 27 March 2019 09:32 Experts still working on repairing one of the synch RF. Parts needed to be removed from Inner area to be repaired. Update @ 11:30 27 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 27 March 2019 08:37 One of the synch RF system still causing issues. Update @ 09:30 27 March 2019 07:36 All but two of the synch RF system back on. Update @ 08:30 27 March 2019 07:02 We currently have a problem with some of the RF systems. Investigations are underway. Next up-date at 07:30, if the beam has not been restored by then. 27 March 2019 06:37 Stable MS beam was restored to both targets at 06:15. 27 March 2019 05:52 We are experiencing some issues with beam set-up. These issues must be resolved before we can run at MS. Next up-date at 06:15. 27 March 2019 05:03 The Ion Source has now been changed. Over the next 20 minutes the Injector will be locked up and beam set-up will begin. Beam of varying intensity should be expected during this period. 27 March 2019 02:30 Beam off for Ion Source change. 27 March 2019 02:18 A reminder that the beam is going to be switched off at 02:30 for an Ion Source change. 27 March 2019 02:00 Although the beam has now been restored, the Ion Source output is much lower than usual and is not responding to adjustments. The decision has been made to change the Ion Source, commencing at 02:30. It is envisaged the source change will take somewhere between 2 and 3 hours. 27 March 2019 01:44 The issue with the Ion Source has not been completely resolved, although it is looking far better; we are therefore hopeful of restoring beam shortly. Next up-date in about 15 minutes. 27 March 2019 01:17 We currently have a problem with the Ion Source - an equipment specialist has been consulted. Next up-date at 01:45. 26 March 2019 17:13 Beam ON 26 March 2019 16:57 Beam OFF - The fan has been replaced and we are currently experiencing beam loss issues running the machine back up. Update in 30 minutes 26 March 2019 16:01 The fault has been located to a failed fan unit within one of the RF systems. This is currently being replaced with a spare unit. Update at 16:30 26 March 2019 14:24 Experts still working on the issue with one of the Synch RF. Update at 15:30 26 March 2019 13:24 We are currently experiencing problems with one of the synchrotron RF systems - expert is attending/investigating. Update in 1 hour 26 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 25 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 24 March 2019 10:16 Beam ON 24 March 2019 09:56 Beam OFF - We are just finishing up the repair and expect beam within the next 10 minutes. 24 March 2019 09:24 Beam OFF - we are having issues with a power supply in the LINAC and will have to access the area to investigate. update in 30 minutes. 24 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 23 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 22 March 2019 23:41 We are experiencing some injector beamloss problems. We believe we have traced the cause to a faulty Tank 3 Quad power supply and are in the process of changing it. Update in 30 minutes. 22 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 21 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 20 March 2019 09:52 Beam ON 20 March 2019 09:48 We are investigating a water flow trip on EVSM7. Update when we have further information. 20 March 2019 09:37 Beam will now be stable. Machine set up complete. 20 March 2019 08:53 Reminder to all ISIS Users: Beam will be running intermittently from 09:00 Hours for approximately 30 minutes. 20 March 2019 08:40 Attention TS1 Methane Moderator Users: a liquid transfer will start in around 5 minutes 19 March 2019 20:47 Beam ON 19 March 2019 20:41 The flow meter has been replaced and we shall now swap back to TS1 and TS2 running mode. Beam will be restored to TS1 in the next 10 minutes. 19 March 2019 20:33 A spare flow meter for the PSU has been sourced and is currently being replaced. Update in 30 minutes. 19 March 2019 19:51 The flow meter is still being investigated. Update in 30 minutes. 19 March 2019 18:21 We have to replace a flow restrictor in one of the EPB1 magnet power supplies. This can take in excess of 1 hour so we will swap to target 2 only while this takes place. 19 March 2019 11:24 Attention all ISIS users: At 09:00 Hours Wednesday 20th March 2019 the machine will be running intermittently and at base rate for approximately 30 minutes. This is to enable the ISIS machine Physicists to rectify some set up anomalies in the Injector.
