I have a very noisy data from a particle accelerator and I want to improve the signal (in every way it's possible): As background: It's data from an electron accelerator which produced Bremsstrahlung when distracted (so it emitted photons towards our detector). Signals have been recorded by coincidence between a tagger for the electron beam and the readout system when the photons hit our detector. Unfortunately our system had a bad shielding/grounding (one of the things we improved as a result). But nevertheless to get a better overview we want to analyze the signals respectively want to filter the signals. My first step is to implement a low pass filter into the software. Can you advice something else? From our horizon most of the noise comes from the avalanche photo diodes. So the readout chain is as following: Photon hits detector -> detector produces light -> light hits two neighbouring avalanche photo diodes -> signal is amplified and shaped by an ASIC -> signal is stored after being transmitted through some electronic components.
For a better feeling I attached some signals. Two adjacent signals represent one detector signal. I picked a few very different ones.
I would highly appreciate any help!
