Charge by Janos Kirz to the ALS AP group:

Challenge: 1 in which we are probably interested, 1 not ...

1. 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 ...
2. 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
3. Short pulses in bending magnet ? Crab-cavities ...
4. 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 ... ?
