how to find the public data in the gamma portal
How to look at the sample scripts ?
for some Beamlines implemented an online execution option for the sample scripts

description:
Experiment: THz streaking
Beamline: FL21
Instrument: THz streaking
Sample: Neon
The data was taken as part of the THz streaking photon diagnostic shifts. it contains GMD data and Time of Flight data ( recorded with the FLASH GHz ADCs) as well as beam arrival time (BAM) data.
we show how to read and interpolate the GMD data, look at the TOF data and sort a delay scan with the BAM

Description:
Experiment: time-resolved RIXS
Beamline: PG1
Instrument: TRIXS end station
Sample: Si
Sample was pumped with an optical laser and probed via soft X-ray RIXS by
varying the time delay between the optical laser and FEL.
Time delay was changed repeatedly from 2935 ps to 2939 ps (these are the delay
line encoder values of the optical laser ) in steps of 400fs, 1000 samples per
delay step.
RIXS images were collected via CCD camera (not full chip, only narrow region of
interest), operated in long exposure mode of 5 sec (integrating several FEL
trains per image).

Description:
Experiment: time-resolved momentum microscopy
Beamline: PG2
Instrument: HEXTOF
Samples: Chessy and Gd/W(110)
Run 44762 was measured with a Hg lamp on the test "Chessy" sample to calibrate FoV in µm in the PEEM mode.
Runs 44798 and 44799 - optical spot profile measured in PEEM mode under the same settings as run 44762
with two different attenuations of the pump laser to determine the spot size of the pump laser.
This is needed to estimate pump fluence during trMM runs (44824, 44825, 44826 and 44827) using values
of I0 monitor of the pump laser.
Runs 44797 - measured with 36.2 eV in k-mode with manually variable sample bias from 28 to 32V by 1 V
every 2000 shots to calibrate the energy scale.
This energy calibration has to be used for trMM data.
Runs 44824, 44825, 44826 and 44827 were measured from Gd/W(110) sample which was pumped with
a 1030 nm s-polarized optical laser and probed with 36.2 eV for time-resolved momentum microscopy (trARPES)
varying the time delay between the optical laser and FEL. The time delay was changed in ZigZag manner repeatedly
from 1462.00 ps to 1464.85 ps with 200 steps and 1 sec waiting time at each step.
