of Primary Investigator and Representative at DESY (if not Primary Investigator) seperated by comma
Name of the experiment *
Goals set for this study block *
ARD or FEL-Studies ?
Is your study generell accelerator research (ARD) or studies to improve the performance of the FLASH machine or to prepare a user beamtime (FEL-Studies) ?
ARD (general accelerator development, not used to improve the performance of FLASH)
FEL-Studies
Commissioning (to get FLASH back into operation again after reconstruction)
Is this the last possibility for measurements: *
yes no
Is this part of a PhD thesis: *
yes no
What do you need?
stable beam
FEL radiation
FEL radiation with spec. polarization
change LINAC magnets
change beam charge
work on RF / LLRF / modules
work on injector laser(s)
work on seed laser(s)
insert LINAC screens
use Laser Heater
use LOLA
use FLASH2 PolariX
Electron beamline *
In which electron beamline you want to work? Multiselect of BLs is possible, we will try to schedule beamtime in the other electron BL, if possible.
