“…Synchrotrons are very large devices that only nation-states can afford. Recently, however, a few groups throughout the world have begun developing a new type of radiation source which employs inverse Compton scattering (ICS) [47][48][49]. An ICS source has the potential to rival synchrotrons for FLASH-MRT with a tractable footprint and cost.…”

“…X-rays at ThomX [17] are produced as a result of the inverse Compton scattering (ICS) when a high-power infrared laser pulses are made to interact with ∼50 MeV electron bunches. These electrons are initially extracted from a photo-cathode with an ultraviolet laser pulse and are accelerated to ∼5 MeV using a 3 GHz 2.5 cells RF gun and then accelerated to higher energies (∼50 MeV) with a 3 GHz traveling wave accelerating section (ACS).…”

The stability and the quality of particle beams is of utmost importance for many emerging linac installations. The impact on beam properties damage of beam electromagnetic element misalignments and jitter/ﬂuctuations in various accelerator sub-systems should be properly known, as usually such shot to shot ﬂuctuations cannot be avoided. On top of that, knowing which parameters the machine is most sensitive is of utmost to take precautionary measures to reduce the beam degradation and thus improve beam stability and quality. This simulation work focuses on a 50 MeV Sband linear accelerator based on RF photoinjector electron source. The sensitivity of the beam parameters towards several errors has been studied collectively as well as individually for each accelerator element. While, the emittance at the end of the linac is dominated by the laminar behavior in the accelerating section, the main emittance degradation comes mainly from orbit errors located at the linac entrance.

“…For these parameters, equation ( 12) also confirms that a large bunching factor, and hence significant coherence, the emission is confined to a central cone of angle Θ SR = arcsin 1/(σ ⊥ k) , which for small angles Θ SR 1/(σ ⊥ k). As mentioned, the typical transverse waists of electron bunches in ICS sources is several micrometers [4][5][6][7][8], ensuring that Θ SR is small for x-rays.…”

Photon yield of superradiant inverse Compton scattering from microbunched electrons

et al. 2022

Compact X-ray sources offering high-brightness radiation for advanced imaging applications are highly desired. We investigate, analytically and numerically, the photon yield of superradiant inverse Compton scattering from microbunched slectrons in the linear Thomson regime, using a classical electrodynamics approach. We show that for low electron beam energy, which is generic to inverse Compton sources, the single electron radiation distribution does not match well to collective amplification pattern induced by a density modulated electron beam. Consequently, for head-on scattering from a visible laser, the superradiant yield is limited by the transverse size of typical electron bunches driving Compton sources. However, by simultaneously increasing the electron beam energy and introducing an oblique scattering geometry, the superradiant yield can be increased by orders of magnitude.
