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
Is this the last possibility for measurements: *
yes no
Is this part of a PhD thesis: *
yes no
What do you need?
stable beam
>30 bunches
>100 bunches
FEL radiation
FEL radiation with special polarization
seed FEL radiation
THz radiation
change LINAC magnets
change beam charge
work on RF / LLRF / modules
work on injector laser(s)
work on LH laser
work on seed laser(s)
insert LINAC screens
use Laser Heater
use LOLA
use FLASH2 PolariX
Electron beamline *
In which beamline you want to work? Multiselect of BLs is possible, we will try to schedule beamtime in the other electron BL, if possible.
FLASH0
FLASH1
FLASH2
FLASH3
THz@FLASH1
Do you required a certain beam energy ? *
560 MeV
750 MeV
950 MeV
1350 MeV
It doesn't matter
whatever energy is needed to reach the wavelength given below
special energy required
Special electron beam conditions required ?
required FEL parameters
Give all required wavelengths, with scan ranges, required FEL pulse energy, pulse number, rep. rate, pulse duration and special requirement (e.g.: polarization)
Photon diagnostics
Do you require any speial photon diagnostics and support using it
How much beam time you need in this block
Give the number of hours you need in this block! (e.g.: "16" )
Maximum length of one beam block
in hours
When your are NOT availaible for beamtime
e.g.: 01.11.2025 - 03.11.2025, 6.11.2025
Any further important information for that beam request
