+===== Summer Study  ===
+We  hope to see you at both AF6 and related sessions at the Seattle meeting, http://seattlesnowmass2021.net/.  This will be a very good opportunity to discuss with colleagues and convey the potential of advanced accelerators to advance high energy physics, as well as the need for strong R&D to realize that potential.  In addition to AF sessions, sessions with the Energy and Theory frontiers as well as Computational (including accelerator simulations) and Community (including workforce and DEI topics) and others will be important. The Seattle program is on Indico:

 **Description:** The purpose of this interest group is to organize and coordinate community input for the Snowmass process via AF6 (Accelerator Frontier - Advanced Accelerator Concepts) on the topics of plasma-based and advanced structure-based accelerators. This includes accessing the status of current R&D, formulating an R&D strategy that addresses the near, mid and long term plans, reviewing and revisiting the advanced accelerator roadmap, and organizing and coordinating the writing and submission of white papers to Snowmass. This will involve coordination with the Snowmass Frontiers (e.g., Energy Frontier and Theory Frontier) on various topics, such as possible collider options (e.g., gamma-gamma and electron-positron) for very high energies (>10 TeV).  White papers falling under this group presently include:

 **Description: ** The Beam Delivery System (BDS) is a critical component of a high-energy linear collider. It transports the beam from the accelerator and brings it to a focus at the Interaction Point. The BDS system includes diagnostic sections for measuring the beam energy, emittance, and polarization, as well as collimators for machine protection. The length of the BDS system increases with collision energy. Higher collision energies also require higher luminosities, and this is a significant constraint on the design of BDS systems for energy-frontier machines. Here, we compare the design of BDS systems based on traditional quadrupole magnets and novel plasma lenses, with the goal of producing a compact system that scales to the 10-TeV regime and provides excellent luminosity per input power.
-Note: it is under discussion where to include interaction point physics and other beam manipulation at this point, and updates will be posted.

-**Description**:   Alternate multi TeV/m gradient concepts although originally envisioned many decades ago using bulk modes in crystals have remained unrealizable. This un-realizability using crystals arises from the disruptive collisional effects such as energy loss, emittance degradation and severe filamentation of the beam which can be overcome using nanomaterials. With the recent opening up of the possibility of attosecond x-ray pulses of high intensities, a scheme of driving Carbon nanotubes with these x-ray pulses has been proposed and is being investigated. While the development of x-ray pulses may be expected over the next decade or so, a new scheme utilizes the sub-micron charged particle beam such as the electron beams currently being commissioned at FACET-II for the excitation of nanoscale plasmonic modes in nanomaterials to access tens of TV per meter acceleration and focusing gradients. Realization of ultrahigh gradients of tens of TV per meter fields using collective modes in nanomaterials  may be promising for HEP as well as in a wide range of areas of research that utilize beams of high-energy particles or photons.

-**Description**:  The whitepaper will summarize plans of five beam test facilities, supported by GARD in support of SC mission. The facilities provide access to a suite of complementary and diverse capabilities for a broad community of scientists representing universities, industry and National laboratories to advance accelerator technologies for the next generation of SC research facilities, basic research in accelerator and beam physics, and education and training for future scientists and engineers. An effort to re-examine priorities and update roadmaps for Advanced Concepts and identifying needs for demonstration and beam test facilities will be attempted. Partnership with universities will be discussed for training of the next generation of leaders in accelerator physics, developing the workforce with skills to build and operate the next generation of SC research facilities that requires specialized facilities suitable for hands-on training.\\

 ===== Topics=====
 The frontier will focus on the high gradient schemes that are being developed, the new physics capabilities that could be enabled, the major challenges that need to be addressed to enable physics machines using these new concepts, and the development time and cost scales.  The path from current results towards achieving beam parameters required for applications, particularly high energy physics (HEP) colliders at the TeV scale. Ultimately, future colliders for High Energy Physics also require development of particle beam generation, diagnosis and manipulation methods which advanced accelerator concepts can also contribute to. We will also include consideration of intermediate applications, such as compact radiation sources, which will develop these technologies along the path to a potential future collider.
