AF7 - Subgroup RF - miniWorkshop on Innovative Design and Modeling

Tuesday 26 Jan 2021, 09:00 → 17:30 US/Central

The AF7-rf group will host this miniWorkshop on Innovative Design and Modeling. The goal of this workshop is to discuss the submitted LOIs in this topic, learn about future research plans, discuss important HEP technical challenges and strategize as a community for our collective contribution to Snowmass. Events will be held in coming months for additional categories of LOIs submitted to AF7-rf.  

This meeting will take place on Zoom. Participants must register to receive the link.

The discussed SNOWMASS LoIs can be found here.
