Digitized Waveform Processing for Fast Timing

The prospect of pileup induced backgrounds at the High Luminosity LHC (HL-LHC) has stimulated intense interest in technology for charged particle timing at high rates\cite{challenge}. In this paper I report on a framework for fast timing sensor and related electronics development used primarily within the context of PICOSEC. Our collaboration accumulated a large ($\sim$fewTbyte) set of waveforms from timing sensors based on MicroChannel Plates(MCP), MicroPattern Gas Detectors(MPGD) and capacitive readout Avalanche Diodes (aka HFS) with typically 20-40 GSa/s waveform sampling. We have reported charged particle time resolutions of 3.6, 24 and 20 picoseconds, respectively for these sensors. In this paper I discuss some of the tools developed during this activity for the processing of waveforms digitized at sampling rates ranging from 40 MHz (ATLAS ZDC) to 40 GHz (PICOSEC).
