  1. BLIP operations 03-22-11 Status – running at 117.5MeV BLIP weekly average beam reduced to 98.4µA purposely, actually ~92µA for 4 days while Ga target in beam, then ~104µA over the weekend without Ga target. Weekly operations decreased to 149.4 hours due to Linac mod 3 failure and BLIP repair of target drive. Isotope production of Sr-82, Ge-68 and irradiation LBNE targets downstream of the isotope targets continues at reduced current. Operations issues Target drive system failure on 3/15 The sprocket on drive #2 was slipping on the motor shaft due to loose set screw. Simple repair required access to the contaminated motor housing on top of the hot cell, so most down time was due to preparation of paperwork.
