DB updated parameters and a first look at power flow and overall consumption B. Jeanneret, R. Corsini – 23 Apr 2007
• MB Bunch spacing 7 8 buckets• MB Bunch population 5.8 109 5.2 109
• HDS power 76 MW 69 MW• RF pulse length 244 ns 297 ns• MB train length 154 ns 207 ns
Alexej used frep = 44 Hz
We use below, as discussed, frep = 50 Hz L1 = 3.75 1034 cm-2 s-1

Comments
• Nb stations : 32 26 , L= 810 m
• IDB : 100 A 95 A
• E : 2.0 GeV 2.35 GeV
• Igor asked for suppressing the detuning of the DB
the presently assumed form factor FDB=0.93 includes as well the remaining inefficiency after detuning compensation – about 5% with old parameters.
Now with no detuning, the losses should be about 1.5 % only. FDB will be updated (to better), when all other small inefficiencies will be
reconsidered.
