Response Refactoring

Brett Viren — Tue, 03 Jul 2018 22:59:30 GMT

In WCT we try to follow the mantra "everything is a component". One corollary to that is we try to avoid hard-wiring dependencies by having functionality accessed by hard-wired construction of concrete classes. The various classes having to do with responses suffered from not being available as components. This led to the entire toolkit having hard-wired behavior which hampers support for multiple detectors. This post describes some recent steps to fix this problem.

Pgrapher Configuration Improvements

A powerful new idiom has been developed to simplify developing Jsonnet configuration files for Wire-Cell toolkit's Pgrapher app component.

Basic Simulation Essentially Working and CellTree support

Hanyu Wei has done great job getting the basic drift and response simulation finished. In particular it now properly handles the exceeding fine-scale interpolation that is essential for having realistically smooth induction signals as a particle's ionization track moves from the region around one field response path to its neighbor. This improvement makes negligible impact on speed. Also included is proper drift processes and their statistics as well as the introduction of an addition RC response for amplifier after the preamp (for MicroBooNE).

Hanyu also added a new frame sink to write out "celltree" file format. This ROOT-based format has been used for a while now to transfer data between the Wire-Cell Prototype and other applications.
