At 3:07 a.m. on May 5, the Antiproton Accumulator broke the record
for the longest sustained operation, approaching the forty-day mark and still counting. The Accumulator has now continuously
held a stack of antiprotons since March 26.
"As long as we maintain the stack, the clock keeps ticking on a new record,"
said Elvin Harms, head of the Antiproton Source Department. "That both the
Accumulator and Debuncher rings have been operating continuously without a
significant failure since March 26 is a remarkable achievement especially
considering their complexity."
The previous record, achieved in December 1987 just as the Antiproton
source was entering a planned shutdown, was 39 days, 9 hours and 36 minutes.
The previous record for longest sustained stack in normal operation, 34 days,
was set in July 2003.
"The talent and commitment of many people in the Fermilab community,
not just one or two, make things like this happen," said Harms. "I'm
proud of the members of the Pbar department - this record reflects their
hard work and attention to detail. At the same time we're indebted to
everyone who works with us in operating, maintaining, and upgrading the
Antiproton source."
