Capabilities for beamNetUS experiments utilizing Laser Plasma Accelerators at LBNL's BELLA Center

Laser plasma accelerators (LPAs) have emerged as a promising alternative to conventional radio-frequency linear accelerators for a variety of beam physics and light source applications, due to their ability to produce high brightness electron beams from compact, laser-synchronized plasma sources. At the LPA source, these beams have high peak currents (multi-kA), are dense (tens of pC in micron-size transverse dimension), have a low-emittance (~micron normalized emittance), and are at energies of 100s of MeV after only mm-scale acceleration. In the context of the new DOE HEP beamNetUS program, we have opened up the Hundred Terawatt Thomson (HTT) LPA facility and auxiliary labs at the BELLA Center to conduct experiments on laser plasma accelerators. In this talk we will present the expertise of the operational team, describe the available hardware, and discuss potential experiments that can be supported. Unique capabilities on HTT include the availability of a second multi-TW laser in the target chamber that is synchronized to the 100s-MeV-class LPA electron beam, electron beam focusing optics, as well as an array of plasma, optical, X-ray, and electron beam diagnostics.
