On 2/11/09 at 09:34, beam was lost as a result of Storage Ring Vacuum Valve 
fault in Sector 39. Vacuum group personnel have made their initial investigation 
and have found that repair will require an access into Zone F. We do not expect 
to have beam before 12:00 pm. Updated information will be e-mailed after the 
access and repair are underway.
