Web-based event display for LArPix data

Pixelated LArTPC event display

This package provides a web-based, interactive event display for pixelated LArTPCs. It is compatible with a variety of multi-modular detector geometries (Module-0, ProtoDUNE 2x2).

The application is deployed on Spin at NERSC, and is accessible from the web browser at https://larnddisplay.lbl.gov/.

Installation

In case you would like to run the application locally, you can clone the repository and install it following these instructions. The package requires larnd-sim but it doesn't need a GPU, so if you don't have one you can remove cupy from the list of packages needed by the setup.py of larnd-sim.

Once you have installed larnd-sim you can proceed with the installation of this package.

cd larnd-display
pip install .

Usage

In order to run the event display you need to start the server:

evd.py /location/of/larnd-sim

where /location/of/larnd-sim is the directory where larnd-sim resides.

The event display will be available at the URL http://localhost:5000/ and should like the screenshot below (for a Module0-like detector):
