Discussion * Peter will present at FCC week in Munich at the end of January. We can review the slides drafts and discuss what new results we can show. FCC-ee at Z simulations with crossing angle, incoherent pair generation, and radiative Bhabha photons would be ideal. Possibly also with crab waist scheme? * Jan has started using WarpX with a student. Any issues? One point to clarify: WarpX should work with IPC and radiative Bhabha in a single simulation. Needs testing, though. * Anna Kinderman, 2nd year PhD student rotating at SLAC with Spencer, will work on a tool to convert GUINEA-PIG outputs into OpenPMD files. * Interfacing with Geant4: Jan has added a fix in GUINEA-PIG, WarpX team has a meeting with Severin to discuss OpenPMD plugin in Geant4.
