E127 experiment finishes on a successful note )) Congratulations to the entire team !!
Entry  Tue May 19 16:48:15 2020, Laszlo, General, E127 beamtime overview,  E127_beamtime_overview.pngE127_beamtime_overview.pdf
Here is a representation how was the time management during E127. The time, what we could spend with measuring the 118Te(pg), was ~20% comparing to the
given 6days.
Entry  Fri Nov 15 10:46:12 2019, Laszlo, Detectors, Detector movement from HKR,  IMG_20191114_135600.jpg
To move the detector remotely from the HKR:
-go to a desktop of a HKR computer
-right click: "App Launcher PRO"

Run stopped for detector fillings

Jan is filling the detector after run0137.
Entry  Tue Mar 10 08:52:34 2020, Jan, Detectors, DSSSD positioning,  optimum_detector_position_2.jpg
To find a good Si position, we need to follow a procedure similar to this:

1. Si in max-in position
Entry  Sat May 22 16:28:10 2021, Laszlo, General, DSSSD movement, 2021 
The DSSSD is moved back to its measurement position(-25mm).
Entry  Fri Jun 5 14:06:15 2020, Laszlo, Detectors, DSSSD and SCRAPER position estimate for Xe and Te experiments, 2020 SP54120060514100.pdfDSSSD_new1.pdfIMG_20200321_025644.jpg
We don't know the exact absolute positions of the detector (+scraper) and the beam. However, what we have to know is only these two relative positions respect
to each other. To get this distance I use two methods:
1, combining the infos from the set position during the beamtime + the measured pg peak position on the detector. The pg peak position is defined only
Entry  Wed Nov 6 14:13:53 2019, Jan, Laszlo, Detectors, DSSSD - 1st movement - realignment,  
We moved the new detector installation for the first time slowly into the dipole chamber.
The alignement seems to be pefect, no distortion or vertical movement of the detector-arm was observed from the window flange.
Entry  Tue Feb 2 13:59:00 2021, Jan, Detectors, DSSD installation and alignment, 2021 
The DSSD has been exchanged and aligned in 
November 2020. After bakeout at 140°C 
(externally, 120°C at internal temp. Sensor)

During the detector test [URL=https://elog.gsi.de/esr/E127/284]test measurements[/URL] with alpha source the allocation of the 16 X- and 16 Y-channels has
been checked.
Entry  Sat May 22 14:53:34 2021, Beatriz et al., General, DSSD Movement, 2021 
DSSSD moved to the most in position in order to try to scrape the beam with the scraper.
