US 2020/0085388 A1 · COMPACT TUNABLE X-RAY SOURCE BASED ON LASER-PLASMA DRIVEN BETATRON EMISSION

Abstract

Systems and methods for generating tunable x-ray emissions including a tunable x-ray source that includes a driver, such as a laser, configured to generate one or more driver pulses, such as one or more laser pulses, and a target source configured to emit a target material. The target source is arranged so that the emitted target material intersects a propagation axis of the driver pulse(s) and the target source may be configured so that the emitted target material has a tailored density profile along the propagation axis of the driver pulse(s), the tailored density profile along the propagation axis having a first density peak region followed by a lower density region followed by a second density peak region, e.g., in an “M” shape.

Dependent claims

A tunable ultrafast x-ray source, comprising:

a driver configured to generate a driver pulse;
a target source configured to emit a target material having a tailored density profile along a propagation axis of the driver pulse, the tailored density profile along the propagation axis having a first density peak region followed by a lower density region followed by a second density peak region,
wherein interaction of the driver pulse with the target material along the propagation axis results in betatron emissions in an x-ray wavelength range.

Dependencies are inferred from the claim text.
