Description
The Spallation Neutron Source is developing a particle accelerator digital twin called Virac (Virtual Accelerator) for testing control room applications and training personnel and machine-learning models. Currently, Virac consists of PyORBIT, a Particle-in-Cell accelerator model, with model parameters read from and written to an EPICS server. As part of being a true digital twin, Virac maps the model parameters to the parameters as seen by operations. While this is straightforward in some cases, acceleration phase of the cavities requires determining the relationship between the reported operational phase and the physics model phase of each cavity. This is a report of how the relationship between these phases is determined for Virac, enabling online modelling of the acceleration cavities.
