The Shutter isn’t opening

  1. Has it been more than 3 minutes? 
    If you have not been taking beam into the hutch recently, GDA will wait 3 minutes to open the shutter.

  2. Check the gas levels (User information screen).

    1. The PCO gas (Argon Technical Grade) should flow at 1.7 SCCM

      2. Check regulators on the bottles themselves.

    2. If gas has run out call EHC’s to replace (8787) – let them know which gas and which grade (Argon – Technical, Helium – BIP).

  3. Check shutter interlocks

    1. On User information screen check interlock icons - all should be bright green after opening the shutter.

    2. If Guardlines Status is not bright green - Search and lock the hutch again.

    3. For anything else contact BL Staff (Through EHCs if out of hours).
