RadiaSoft develops the open source CAE gateway, Sirepo. The Sirepo gateway supports a majority of free users and some paying subscribers, including the US Particle Accelerator School. Stanford and other educational programs are supported as a community service. Sirepo includes an embedded JupyterHub instance with pre-installed community codes and is also instantiated privately for enterprise customers. RadiaSoft consulting supports all the technical domains of interest to our Sirepo customers.
