Pulse-shape discrimination from statistical moments, without per-channel calibration

In an organic scintillator, a neutron and a gamma of the same deposited energy produce pulses of the same height. What differs is the shape: the neutron recoil populates triplet states that decay slowly, so its pulse carries a delayed tail the gamma does not have.

Closing the gain-stabilisation loop inside the FPGA

A silicon photomultiplier changes its gain by roughly one percent per degree. A photomultiplier tube drifts with supply, with count rate and with its own history.

Per-channel health monitoring on an array, out of a single engine

A 16-channel SiPM array, a multi-anode PMT, a strip detector, a segmented drift chamber. They all share a problem that a single-channel instrument does not have: at any moment, some channel is probably misbehaving, and nobody knows which.
