AHCAL and BIF Test Beam at DESY (July/August 2016)
We had 2 weeks of beamtime at DESY, TB24, from 25/07 to 07/08. Elog is available here : https://ttfinfo.desy.de/CALICEelog-sec/show.jsp?dir=/2016/30/26.07&pos=2016-07-26T21:09:48

Hardware under test
HBUs
- 8 “old” sensl HBUs (already used in 2015): at DESY
- 1 first SM HBU (already used in 2015): in Mainz, to be sent to HH
- 6 new SM HBUs
- 5 at DESY
- 1 in HD: to be sent to Mainz for tile assembly, then to HH
HBU commissioning
- “standard” program as before: hold time, LED scan for gain,
- new: in climate chamber at 20(or 25?) degrees
- new: have first MIP estimate from cosmics in Mainz
- to be understood: different hold values for LEDs and MIPs
- to be done: check LED uniformity, trigger threshold
interfaces
20 sets of interfaces expected on July 5 or 6
Data taking programme:

MIP calibration in airstack
Default setup
We perform MIP calibration in the airstack using a default setup of 15 single modules, as summarized in the table. As the MIP signal is degradad for the latest modules, we have repeated the measurement three time, each of them, removing a set of the first 5-4 modules from the airstack.

During the first round of MIP calibrations runs, the layer 12 had to be removed of the runs. https://ttfinfo.desy.de/CALICEelog-sec/show.jsp?dir=/2016/30/28.07&pos=2016-07-28T13:42:47
Second setup
We removed the first 5 layers and also the layer 12th since had failed during previous runs, so we can perform the calibration of the following 5. see https://ttfinfo.desy.de/CALICEelog-sec/show.jsp?dir=/2016/30/28.07&pos=2016-07-28T13:42:47

Setup (basics):
DAQ software
A wiki for the new monitoring system is up here : http://flcwiki.desy.de/AHCALMonitoring_DQM4HEP, general instructions can be found in the operation section of this wiki.
Here you can find a wiki about the EUDAQ for AHCAL and BIF
Visit http://flcwiki.desy.de/tb2016 for more information.
Signals & Logics (electronics)
The setup is very similar to the one used in previous testbeams.
Electronics picture.
For previous setups, see for example http://flcweb02.desy.de/flcwiki/AHCALTestBeamCERN2015/#Electronic_setup_and_cabling:_diagrams_and_pictures .
I the present case, we only use two scintillators (placed in front of the detector) and we also used the BIF.
We are using two scintillators placed between the beam and the detector as validation signal. Both scintillators are thin sticks of about 1cm width and 15 cm lenght and both are crossed in order to set horizontal and vertical position with high precision. The coincidence signal is fed into the CCC to be used as validation signal.
The two signals from the scintillators and from the coincidence is conducted to the BIF also.

LED runs with EUDAQ
0)
Prepare Labview:
- load ET_IC slow control files
- go to Calib tab and click
- SET (Delay Lines)
- SET (DACs VCALIB)
- Enable TCALIB (5) and click SET
- Go to Take Data tab and click SET Setup Lab Mode.
- Choose the paths and click autopath, autolisten and listen.

Long LED runs
1)
cd /home/calice/Desktop/eudaq-configuration/calice_ahcal/conf_longLED_July
source create_from1file.sh
The script generates the configuration files in the eudaq pc, the labview configuration files in the eudaq pc also and sends the copy to the labview pc. It also creates the eudaq folders if needed.
(see header of the script)
echo "Script to generate the EUDAQ configuration files for long LED runs" echo "usage: source create_from1file.sh -l(--labviewConffolder) LabviewPCConfigurationFolder -v(--v0) V0 -n(--nvoltages) NVoltages -s(--step) dmv_step -r(--readoutcycles) CYCLES -e(--eudaqfolder) EUDAQdatafolder -c(--createDatafolder) y/n" echo "requires the existence of:" echo " a) the xxLED.conf file, see the end of the script to see how it should look" echo " b) the longLED_wind/LED_00.ini file, see the end of the script to see how it should look" LABVFolder="longLED_July2016" NV="91" V0="3500" dmV="50" CYCLES="3000" EUDAQ_FOLDER="20160729_long" MAKE_DIR="y"
2)
cd /home/calice/Desktop/EUDAQ1.6/producers/calice/scripts
./LED_2016
3) choose the /home/calice/Desktop/eudaq-configuration/calice_ahcal/conf_longLED_July/LED_00.conf file
4) START.
Short daily LED runs
1)
cd /home/calice/Desktop/eudaq-configuration/calice_ahcal/conf_dailyLED_July
source create_from1file.sh
The script generates the configuration files in the eudaq pc. It also creates the eudaq folders if needed.The labview files should be already generated by the experts.
2)
cd /home/calice/Desktop/EUDAQ1.6/producers/calice/scripts
./LED_2016
3) choose the /home/calice/Desktop/eudaq-configuration/calice_ahcal/conf_longLED_July/LED_00.conf file
4) START.

Theme
Following the tradition started in May2016, to feed the shifters urges of artistic beautiness and compensate the lack of natural light in the hut, a set of wallpapers was prepared and loaded in the PC's.
This time Sara Herranz, Paula Bonet, Conrad Roset and Laura Agustí illustrations accompanied us during the testbeam installation, debugging and data taking phases.
