BLIP Operations May 28-June 4, 2013
Operations at
139.5
MeV
and 117.5
MeV
for and
Sr-82
production until .
Weekly average intensity was
87.1 µA
for
158.5
hours on target, but
intensity lowered for weekend operations with
Ga
target.
Ac-225 research irradiation
successfully 139.5
MeV
ended May 30.
Chiller for target cooling water failed later on May 30. High temperature alarm shut beam off. F&O diagnosed the problem as a failed pressure switch but had no spare immediately available. The dual chiller operation was separated and operations resumed with one chiller at reduced beam intensity. F&O repaired the switch on May 31 and regular BLIP operations resumed.
Radiation damage experiment for LHC commenced this morning at 200
MeV
.
IAEA inspector training is taking place today at BLIP with hidden Th-227 and Hg sources.
Operations at the Target Processing Lab (TPL)
French
produced Sr-82
expected
to arrive on Friday
only arrived this afternoon. In order to combine
with our
current batch overtime effort will be necessary for the next few days.
Hot cell “guillotine” port hole broke yesterday preventing any transfer of BLIP targets. Repair needed rigger assistance to disassemble. Repair completed just before lunch today.
