A virtual conference will have some advantages over an in-person conference. We will work to maximize the benefits of the virtual format. The conference will include invited oral talks by video-conference (in a format similar to IPAC 2020 and Linac 2020), and several virtual reality poster sessions (in a format similar to the 2020 Neutrino Physics and Astrophysics Conference hosted by Fermilab). With the need to accommodate different time zones, the sessions will be limited to 4 hours per day (time zone info below). A session for “virtual lab tours” is considered at the end of the conference, with the possibility for participants to learn about their choice of several labs around the world. Best student poster prize and best young researcher presentation prize are also planned. In addition, a tutorial program by video-conference is planned in the week preceding the conference.
