Study beam time request form

with this is beam time request form you can request beamtime for the Periods from:
- 14.09.2026 until 04.10.2026 (KW38 - 40)

as well as grey shift studies (in FLASH1) from:
- 05.10.2026 until 25.10.2026 (KW 41-43)

and maybe grey shift studies in FLASH2 from:
- 26.10.2026 until 02.11.2026 (KW 44)


submission deadline 17.08.2026

formular to request study beam time

Email Adresse *
of Primary Investigator and Representative at DESY (if not Primary Investigator) seperated by comma. (You can also add further participants.)
Passwort *
don't use your DESY Password! It will appear in the ticket! Use the same password as the last time it is related to the mail address .
Name of the experiment *
Goals in this study block *
Is this the last possibility for measurements? *
yes no
Is this part of a PhD, master or bachlor thesis ? *
Yes No
Electron Beamline *
will work in gun mode
will change LINAC
FLASH1 with e- beam
FLASH1 with FEL radiation
FLASH1 with THz radiation
FLASH2 with e- beam
FLASH2 with SASE
FLASH2 with afterburner radiation
FLASH3
parallel use of the other electron beamline is not possible
Beam energy *
560 MeV
750 MeV
920 MeV
1300 MeV
1350 MeV
does not matter
beam energy which fits to FEL parameters
special energy
required parameters (bunch number/ rep. rate / pulse length / wavelength (fundamental or third harm.) + single pulse energy at that wavelength / ...)
You or your colleagues setup the FEL by yourself or do you request an initial setup *
we will setup ourself
a pre-setup of the accelerator is required
needs
insert LINAC screens,
use Laser Heater,
work on Laser Heater
use LOLA,
use FLASH2 PolariX,
work on injector laser
special requiremnts
How much beam time you need for this study in this block in total? *
in hours (e.g. 24h)
Maximum length of one beam time in one go? *
(without interruptions) in hours (e.g. 8h)
When your are NOT availaible for beamtime ?
even you don't want grey shifts add KW 33-37, since there will be 6 study days in that periode.
Do you have any further important information for that beam request ?
