WG5 - Plasma devices, plasma and beam diagnostics

talk

The Plasma Lens Experiment at CERN is an experiment in active plasma lensing. It consists of a gas-filled sapphire capillary connected to a set of compact Marx banks, which breaks down the gas and drives a large current pulse through it. This generates a magnetic field, which is probed using the CLEAR electron beam and measured using various screens and magnetic elements behind the lens. We...

194. Measuring Transverse Displacement Between the Drive and Witness Beam for PWFA

WG5 - Plasma devices, plasma and beam diagnostics

talk

Future beam-driven plasma wakefield accelerator (PWFA) experiments at the Facility for Advanced Accelerator Experimental Tests (FACET-II) will require several detectors monitoring a multitude of plasma and electron bunch parameters. We present simulations demonstrating the ability of an electro-optic sampling beam position monitor (EOS-BPM) to analyze the femtosecond electron bunches that will...

109. Evolution of an ionized plasma column measured by proton beam self-modulation

WG5 - Plasma devices, plasma and beam diagnostics

talk

The AWAKE experiment at CERN is a proof-of-concept proton beam-driven plasma wakefield accelerator. The plasma source is a 10 meter-long Rubidium vapor cell ionized by a high-intensity laser pulse. The proton beam is modulated by the plasma, which results in micro-bunching at the plasma frequency and resonant excitation of the plasma wave. We measure the frequency of the micro-bunching when...

127. Beam Matching in PWFA with a Laser-Ionized Plasma Source

WG5-WG7 Joint Session

talk

Plans for a laser-ionized, beam-driven plasma wakefield accelerator at SLAC’s FACET-II facility are presented. The plasma source is formed by laser ionization of a volume of uniform density gas, and the plasma density profile is therefore determined by the focal pattern of the laser. This offers the advantage of a tunable density profile that can accommodate entrance and exit ramps suitable...
