Quadrupole focused LWFA electron beam driven bremsstrahlung gamma ray source

ORAL

Abstract

Laser wakefield accelerators (LWFA) generate low transverse emittance, ultrashort electron bunches, and produce synchrotron-like light sources. To mitigate the issue of electron beam blowup, quadrupoles are employed to introduce strong focusing and efficient transport of the LWFA electron beams. This research work incorporated focused LWFA electron beams using a triplet quadrupole system along with a lead converter to examine the generation of intense gamma beams. We will discuss the generation of gamma ray beams and emphasize its energy spectrum, energy transfer, number of photons, focusing geometry, and flux through the results obtained by the Monte Carlo simulation of focused LWFA electron beam hitting the copper stack with and without a bremsstrahlung converter.
