Troubleshooting
Beam dump happens
When Beam dump unfortunately happened, there will be no beam and the valves will automatically close. Check the chat panel and Public website for machine status (should be 500 mA for small ring) for updates.
Once the beam is restored: Reopen the valves before resuming measurements.
Order to open valves in front end: V1, BS-01, HA-01 Order to close valves in front end: HA-01, BS-01, V1
HA-01 and BS01 are used for blocking beam, and V1 is used for isolating the vacuum of storage ring.
The beam is opened or closed in this order to prevent direct illumination of beam on V1, which is metal and might melt under illumination.
