====== AF3: Accelerators for EW/Higgs ======
Co-Conveners : Marc Ross (SLAC), Qing Qin (IHEP, Beijing), Georg Hoffstaetter (Cornell)

===== Description=====
Electro-weak physics and the Higgs are currently of major interest to the HEP community and will likely persist into the foreseeable future. Technology for linear and circular e+e- machines are fairly mature. This Group will focus on the remaining technical issues and explore possible cost reduction schemes. Some of the proposed topics are:

  - Question/Topic1 Identification and mitigation of cost drivers
  - Question/Topic 2 Room temperature and superconducting RF
  - Question/Topic 3 Positron sources
  - Question/Topic 4 IR magnets
  - Question/Topic 5 Additional topics related to cost reduction and performance improvement
  - Question/Topic 6 Alternative approaches in the context of EW/Higgs studies such as muon colliders, gamma-gamma, ?

-----------------------------------------------------------------------
AF3 Milestones:
- Meet 16 December 2020  to 
-  step through the report outline, review plans for submissions, and enlist contributors to common sections;  
-schedule meetings to accompany progress of the report.
- plan joint workshops between AF topical groups.

See: (for a compilation of Technology-related contributions). We plan to 'cross-cut' these in the report.
