Schroeder 4 US National Labs: ANL, LANL, SLAC, LBNL; 2 US Universities: NIU and MIT1 US company: Euclid Techlabs2 International institutes: CANDLE SRI, Armenia and Tsinghua Uni. China.Core Message of LOI: 1) the SWFA roadmap presented in 2016 Advanced Accelerator Development Strategy Report needs to be updated.2) Taking example of the plasma wakefield community, the SWFA community need to strengthen the collaboration and coordinate the efforts in the next decade.Key Words: Coherent efforts inside the SWFA communityMore visibility outside the AAC communityMore resources from funding agency

2. Current Status: ANL has one 3-TeV collider concept based on 26GHz short pulse TBA and a 200GHz Colinear wakefield stepping stone facility for the light source application. But many technical issues need to be investigated.For TBA, 400MW rf power, staging, etc, have been demonstrated, but high gradient (>300MV/m) and high energy gain (>500MeV) not yet.For CWA, TR=5, 300MeV/m, etc, have been demonstrated, but sustainable acceleration in meter scale not yet.Challenges and Suggestions: Many challenging issues have not been worked on or in a slow pace, simply because of the limited resources.New directions need to be explored, like THz acceleration, low cost fabrication techniques, etc.Grow the community and attract young talentsLOI-90: Structure Wakefield Acceleration (SWFA) Development for an Energy Frontier Machine
