Contributions to Double

tel-00821629, version 1 - 11 May 2013
Over the last three years, many contributions have been provided to the
Double Chooz experiment. This chapter meant to highlight and describe the
results and the contributions achieved during the development the present
thesis.
First year:
• Installation of the detector read out system, described in Sec. 3.2. The
installation and the following testing of the read out system lasted
about 4 month, from March to June 2010, leading to an indepth understanding
of the detector and various subsystems.
• Raw level analysis of the first detector data, acquired with empty detector
after the read out system installation. The analysis involved
studies of the FADC baseline and single PE charge deposition. Such
studies allow a preliminary tuning of the parameters (i.e integration
time window, charge threshold, etc.) necessary for the pulse reconstruction,
described in Sec. 3.8.1.
• The analysis performed on the first detector data has been found useful
in highlight any misbehaviour of the detector and become later part
of the monitoring system, described in Sec. 3.3.4.
• The critical online system devoted to the onsite data file handling
and transfer, described in Sec. 3.3.3, has been designed as a part of
this thesis. The system maintenance and monitoring has been an
important responsibility for the rest of the thesis.
