13 Dec 2018 | | Abstract: | The SoLid experiment aims to measure neutrino oscillation at a baseline of
6.4 m from the BR2 nuclear reactor in Belgium. Anti-neutrinos interact via
inverse beta decay (IBD), resulting in a positron and neutron signal that are
correlated in time and space. The detector operates in a surface building, with
modest shielding, and relies on extremely efficient online rejection of
backgrounds in order to identify these interactions. A novel detector design
has been developed using 12800 5 cm cubes for high segmentation. Each cube is
formed of a sandwich of two scintillators, PVT and 6LiF:ZnS(Ag), allowing the
detection and identification of positrons and neutrons respectively. The active
volume of the detector is an array of cubes measuring 80x80x250 cm
(corresponding to a fiducial mass of 1.6 T), which is read out in layers using
two dimensional arrays of wavelength shifting fibres and silicon
photomultipliers, for a total of 3200 readout channels. Signals are recorded
with 14 bit resolution, and at 40 MHz sampling frequency, for a total raw data
rate of over 2 Tbit/s. In this paper, we describe a novel readout and trigger
system built for the experiment, that satisfies requirements on: compactness,
low power, high performance, and very low cost per channel. The system uses a
combination of high price-performance FPGAs with a gigabit Ethernet based
readout system, and its total power consumption is under 1 kW. The use of zero
suppression techniques, combined with pulse shape discrimination trigger
algorithms to detect neutrons, results in an online data reduction factor of
around 10000. The neutron trigger is combined with a large per-channel history
time buffer, allowing for unbiased positron detection. The system was
commissioned in late 2017, with successful physics data taking established in
early 2018. | | Source: | arXiv, 1812.5425 | | Services: | Forum | Review | PDF | Favorites | |
