Convolutional Neural Network Applied to BiPo Discrimination at SoLid
Creators
Description
The BiPo-214 decay is a significant background to the antineutrino reconstruction in the SoLid detector. It has a very similar time and spatial signature as of the product of the inverse beta decay. SoLid has developed a unique technique to separate scintillation signals of neutron captured on Lithium-6 from the Po-214 alpha. The current Pulse Shape Discrimination technique is based on a ratio of charge integration window. Using a 1-dimensional convolutional network to fully characterise the shape of the waveform, we demonstrated a factor of two to three improvement in discrimination power over the current technique.
