BC2 Commissioning Parameters
Parameter
Value
RF rate
30 Hz
Beam rate
≤30 Hz
Drive-laser rate
30 Hz
30 Hz during e- commissioning - shutters provide
lower e- rate – possible 120-Hze tests at end or run
250 pC
Start at low charge in BC2/linac – later raise back up
to 1-nC to study high charge
Drive-laser pulse length
6 ps fwhm
6-ps fwhm startup at low charge with later settings of
10-ps at 1 nC
Final beam energy
13.6 GeV
13.6 GeV typically with tests down to 4.3 GeV
Bunch charge
Comments
10-30 Hz e- beam as baseline – possible 120-Hz
tests at end of run
