“…Following our first introduction of a capillary discharge as a plasma source imbedded in the electron beamline [13], we experimentally demonstrated phasing between the longitudinal-and the transverse-components of the wakefields acting on a drive electron-bunch [14]. This research verified the ATF's added capability for supporting experiments with beam-driven plasma wakefield in a compact user-friendly setup, as the ATF's users immediately recognized and appreciated.…”

Abstract. 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. Since its inception, the ATF in fact had undertaken the mission of accelerator stewardship of the Office of High Energy Physics (OHEP), even before the concept was fully formulated. In bringing advanced accelerator-science and technology to individual users, small groups of researchers, and large collaborations, the ATF offers a unique combination of a high-brightness 80-MeV electron beam synchronized to a 2-TW picosecond CO 2 laser. The ATF now the flagship of the Accelerator Stewardship program of the OHEP, and thus will provide opportunities to small businesses to develop accelerator-based products, running the full gamut from the laboratory to the applications. At this juncture, the ATF has embarked upon a transformational upgrade of its capabilities. We describe our plan for greatly expanding the ATF's floor space, and the number of independent experiment halls, for upgrading the electron beam's energy in stages to 500-MeV, and the CO 2 laser's peak power to 100 TW. This upgrade will afford a new, vast space for the laser and electron beam for conducting new research in accelerator science and technology that is at the forefront advanced accelerators and radiation sources, and to support the most innovative ideas in these fields. We will discuss emerging opportunities for scientific breakthroughs that include the following: Plasma Wakefield Acceleration (PWFA), extending the researches already pursued at the ATF; Laser Wakefield Acceleration (LWFA) wherein the longer laser wavelengths will engender a proportional increase in the beam's charge, while our linac will assure, for the first-time, the opportunity for undertaking detailed studies of seeding and staging of the LWFA. The laser will extend proton acceleration to the 100-200 MeV level, as is demanded for certain medical applications.

“…The parameters soon to be achieved with the ATF CO 2 laser BESTIA open up the possibility to perform LWFA experiments at 10 μm. In addition, the ATF has undertaken capillary-discharge experiments where channeling of the CO 2 laser light was demonstrated [20]. Thus, the ATF not only possesses a viable laser driver for LWFA, but has a verified means to confine it over many Rayleigh lengths.…”

Expanding the scope of relativistic plasma research to wavelengths longer than λ≈0.8−1.1µm covered by conventional mode-locked solid-state lasers would offer attractive opportunities due to the quadratic scaling of the ponderomotive electron energy and critical plasma density with λ. Answering this quest, a next-generation mid-IR laser project is being advanced at the BNL ATF as a part of the user facility upgrade. We discuss the technical approach to this conceptually new 100-TW, 100-fs, λ=9−11 µm CO 2 laser BESTIA (Brookhaven Experimental Supra-Terawatt Infrared at ATF) that encompasses several innovations applied for the first time to molecular gas lasers. BESTIA will enable new regimes of laser plasma accelerators. One for example is shock-wave ion acceleration from gas jets. We review ongoing efforts to achieve stable, monoenergetic proton acceleration by dynamically shaping the plasma density profile from a hydrogen gas target with laser-produced blast waves. At its full power, 100-TW BESTIA promises to achieve proton beams at energy exceeding 200 MeV. In addition to ion acceleration in over-critical plasma, the ultra-intense mid-IR laser BESTIA will open new opportunities in driving wakefields in tenuous plasmas, expanding the landscape of Laser Wake Field Accelerator (LWFA) studies into unexplored long-wavelength spectral domain. Simple wavelength scaling suggests that a 100-TW CO 2 laser beam will be capable to efficiently generate plasma "bubbles" thousand times bigger in volume compared to a near-IR solid state laser of an equivalent power. Combined with a femtosecond electron linac available at the ATF, this wavelength scaling will facilitate study of external seeding and staging of LWFA.

Transmission of high-power CO2 laser pulses through a plasma channel

Abstract: A 5 J, 180 ps CO2 laser pulse is channeled by a 17 mm long capillary discharge. Plasma dynamic simulations confirm occurrence of optical guiding conditions along a plasma column of a quasiparabolic radial profile with the minimum axial free-electron density ∼1017 cm−3.
