Selector.C can be used to adjust energy bad reconstruction in the EXL detectors due to energy leak (see the PDF attached for more information about it) once we already have the coefficients for the energy on EXL crystals. To operate with it, for first calibration coefficient must be deduced. Once it is done the slopes and offset of the calibration have to be inserted in Selector.C file at lines 41 (a[19]) and at line 49 (b[19]). After thqt thresholds must be fixed (line 58, tr[19]) and also gains on the pairs. We deduced gains as the ratio between x-axis and y-axis of each uncalibrated matrix: for each pair (1-2,3-4,5-6,...,17-18) we took the ratio between x=2000;4000;6000 and the respective y value, and y=2000;4000;6000 and the respective x values. taking the averages of those ratios; those were than used as the coefficients R1ex[9] and R2ex[9] in Selector.C (all information on those values and how are used are in EXL.pdf).
Once the variables are set, the program can be executed using the batch file in attachement by typing the line root rootdir/run_number.root -b batch -q from terminal. Here "run_number" is the name of the run to use. It will generate then a .root file (in attachement some output file for run 0430.root). Now the name is "whatever_output.root", and can be changed from "Selector.C"
The program also provides randomization of bins for the operation of sym between contiguous crystals

19H
They succeeded to get 90 % transmission with CSS1 but the energy at the exit was changed by 4%, that is not compatible with the CSS2 limit of 1 %. After fitting the CSS1 energy they obtained 70-80 % transmission only, but it is enough. The problem with the HF of CSS2 was solved. They are trying to accelerate with CSS2. They are now at midway inside CSS2. They still need several hours to finish the work.


15H
The problem with CSS1 is not yet solved. They want 90% transmission of the beam in CSS1, they have 75%.
There is another problem, the HF of CSS2 has dysfonctionnements.
They don't expect beam before 20H.
Fixed, e744, Sun May 27 20:47:02 2018, e744- Valérie, DAQ, Hardware, N/A, Info to reboot the crates in case of problem IOLANmust2reboot.pngRunControlE744Ready.png
In case of problems in the run control, if it is not possible to reinstall the crates in the "Ready" mode status,
it is possible to reboot them remotely via the software commands.
this can be done using the iolan windows.
first, open a Terminal, then write:
iolan must2 all
Two windows are opened, for each of the VXI crates. see snapshot IOLANmust2reboot.png
then it is possible to reboot the crates by writing in each of the gansterm terminals the "reboot" command.
(Note that a password is asked, it corresponds to the first letter of all the words between (La cigale ...l'été) in the famous sentence of La Fontaine's fable "La Cigale et la Fourmi" ("The Grasshopper and the Ant").
Then after the operation the run Control Narval should be ready (see snapshot).
If not, it means that we need to enter in the D6 room to reboot the crates directly by pushing the "SYS RES" button (using the tiny yellow screw) on the two crates:
start with the Master crate (ganlx1, the one with the main GMT and MUVI1), then press the button of the second crate (ganlx14, with the GMTslave and the second MUVI).
The click-click on each crate means that the reset is done.
(NB: Simultaneously, the two gansterm terminals show the lines of the on-going reboot operations).

After correcting position for the Must2 detectors by taking into account the real hit position on the target that was (0,15cm,0) and not (0,0,0). The way to do it was to artificially move every detector 15cm lower.

Joined are the results at 0deg, for 14N the resolution increases from 125keV to 102keV.

NB: without beam the current on Telescope 4 is high, between 9 and 11 µA. see snapshot.
NB: The Ioset was increased at 20 µA on Friday 25th (cf Id entry=490) to avoid trips on this telescope due to strong intensity fluctuations due to the beam.
