The SoLid anti-neutrino detector's readout system

Understand

The SoLid collaboration have developed an intelligent readout system to reduce their 3200 silicon photomultiplier detector's data rate by a factor of 10000 whilst maintaining high efficiency for storing data from anti-neutrino interactions.

• The system employs an FPGA-level waveform characterisation to trigger on neutron signals.
• Following a trigger, data from a space time region of interest around the neutron will be read out using the IPbus protocol.
• In these proceedings the design of the readout system is explained and results showing the performance of a prototype version of the system are presented.
