Stable laser-driven Betatron X-ray generation

POSTER

Abstract

Laser-driven Betatron sources, offering a compact and economical alternative for the generation of ultra-short X-ray pulses, are on the rise [1]. Yet, to truly rival existing technologies, these laser-driven sources call for further refinement. Our previous work with M-jet demonstrated the generation of Betatron X-ray with a marked increase in photon number using the Transverse Oscillating Bubble Enhanced Betatron Radiation (TOBER) scheme [2]. In this poster, we present the consistent stability and reproducibility of X-ray generation using the M-jet.

We conducted an experiment at the Advanced Beam Laboratory that successfully demonstrated the M-jet capacity to consistently generate over 1×10^9 photons/pulse in the 2-30 keV spectral range across 181 shots. We also show the average electron energy produced by M-jet exceeds 100MeV/pulse. The experiment was performed using f/25 beamline of the ALEPH laser. The 800nm laser with 9J on-target energy was focused into the M-jet. Our data underscore the M-jet potential in the realm of laser-driven X-ray sources.
