Description
Betatron-radiation emitted by 10 GeV electron beams can range from few keV to 100 keV depending on the PWFA parameters with typically few-fs pulse length.
By itself this combination of parameters is complementary to capabilities of current light source facilities.
In PWFA facilities, control over the electron-beam phase space gives the opportunity to manipulate the properties of the radiation.
By separating double electron bunches with a femtosecond ionizing laser pulse, the ultra-short ionization front lets the trailing bunch
convert energy into X-rays, while the front beam is unperturbed.
The front beam gated out from the plasma remains available as pump for example for strong-field studies on matter with high electronic binding energies or material damage studies.
We will explore the suitability of betatron radiation from PWFAs for such pump-probe studies and how it could apply specifically to the capabilities available at FACET-II.
