“…Studies of electron-beam-driven plasma wakefields have been a notable part of ATFs' research program throughout the last decade. Following our first introduction of a capillary discharge as a plasma source imbedded in the electron beamline [1], we experimentally demonstrated phasing between the longitudinal-and transverse-components of the wakefields acting on a drive electron bunch [2]. This research verified the added ATF capability for supporting beam-driven plasma wakefield experiments in a compact user-friendly setup, as was immediately recognized by the ATF's users.…”

The Accelerator Test Facility (ATF) at Brookhaven National Laboratory has served as a user facility for accelerator science for over a quarter of a century. In fulfilling this mission, the ATF offers the unique combination of a high-brightness 80 MeV electron beam that is synchronized to a 1 TW picosecond CO 2 laser. We unveil herein our plan to considerably expand the ATF's floor space with an upgrade of the electron beam's energy to 300 MeV and the CO 2 laser's peak power to 100 TW. This upgrade will propel the ATF even further to the forefront of research on advanced accelerators and radiation sources, supporting the most innovative ideas in this field. We discuss emerging opportunities for scientific breakthroughs, including the following: plasma wakefield acceleration studies in research directions already active at the ATF; laser wakefield acceleration (LWFA), where the longer laser wavelengths are expected to engender a proportional increase in the beam's charge while our linac will assure, for the first time, the opportunity to undertake detailed studies of seeding and staging of the LWFA; proton acceleration to the 100-200 MeV level, which is essential for medical applications; and others.

Capillary discharge plasma channels have demonstrated guiding of laser beams and may be employed to extend the length of laser-driven accelerators. However, the magnetic field associated with the discharge current may affect the injection of electrons into the capillary. A model for magnetic field generation is presented and analyzed. For a wide range of parameters of interest the magnetic field outside the channel is well described by a diffusion equation. Analytical solutions of the diffusion equation are obtained and compared with numerical solutions. Trajectories, for test electrons starting from outside the capillary, are described and discussed. For typical parameters the deflection of electrons by the magnetic field is small compared with the acceptance of the wakefield.

A plasma channel is a narrow preionized column of plasma that can be used for a number of accelerator applications. Plasma channels play a crucial role in the laser wakefield accelerator (LWFA), where they may provide the acceleration medium as well as guiding of the intense laser pulse and accelerated electron bunch. This paper will review methods for producing plasma channels, optical guiding in channels, and the application of channels to the LWFA. The potential advantages of using long plasma channels in the plasma wakefield accelerator (PWFA) will also be discussed.
