Deb Cooling Time Study • 4s cycle time and changed debuncher cooling OFF timers • Data taken: • Nominal running…every pulse into Acc • DCCT, VSA measurements and production • SEM806 • ARF1 OFF to measure profile on Injection orbit • Every other pulse into Acc (D:ESEPC timer) • DCCT measurement of D/A transfer eff • Previous study showed • SEM in decreases D/A transfer by 1.5% • DRF2 off decreases D/A transfer by 12%
SEM806 2.4s to 2.2s +7.2% +8.2%
VSA Left Over Beam Meas. 2.4s to 2.2s -1.5%
Accumulator DCCT 2.4s to 2.2s -3%
Accumulator Production 2.4s to 2.2s -2% (-5%)
