strax 0.9.1

Streaming analysis for xenon TPCs

strax

Streaming analysis for xenon experiments

Strax is an analysis framework for pulse-only digitization data, specialized for live data reduction at speeds of 50-100 MB(raw) / core / sec. For more information, please see the strax documentation.

Strax' primary aim is to support noble liquid TPC dark matter searches, such as XENONnT. The XENON-specific algorithms live in the separate package straxen. If you want to try out strax, you probably want to start there. This package only contains the core framework and basic algorithms any TPCs would want to use.
