Charge by Janos Kirz to the ALS AP group:
Challenge: 1 in which we are probably interested, 1 not ...
- Have been involved with Alan in the past ... 3 straight sections reserved for accelerator physics.
Boomerang went from 3 to 1 AP straights ... Liberating half of straight 2???
It would be worth 500 k$ to liberate half a straight ...
- Set of questions connected with timing mode for users ...
- There are a variety of people who would like 2-bunch mode 53 weeks a year - many others would
like 0 weeks ... Variable bunch timing ...
- (Combination of chopper and beam kick separation ... ? Resonant driving of camshaft -
then selection of pulses with chopper ... ?)
- time resolved ARPES
- Short pulses in bending magnet ? Crab-cavities ...
- ALS originally 1.5 GeV - now 1.9 GeV - better for few 100 eV to 1 keV
interest in the 6-9 eV regime ... Lower power density ... no polarization control
necessary in sector 9 ??? Get rid of He filter ... ?
