Description
Elusive particles like low-energy neutrinos and dark matter candidates require extremely sensitive detectors to be revealed. In experiments probing nuclear recoils, induced by sub-GeV dark matter particles or CE$\nu$NS, a low energy threshold and minimal backgrounds are mandatory. For these purposes, an advanced offline analysis of triggered pulses from the detector stream can make a significant difference.
The DIANA analysis software offers a portable, fast and open-source toolkit for low-energy physics analysis, featuring sophisticated signal processing techniques and utilities for higher level data fitting and analysis.
The software has been recently upgraded with modified versions of the matched filter, a digital filter for the amplitude estimation of a single waveform. Combining signals from different sensors with a multidimensional matched filter, it is possible to lower the detector energy threshold, and an advanced analysis of the signal shape can aid in signal/background discrimination.
