Proposed Distributed Feedback Crystal Cavities for X-Ray Lasers

Proposed distributed feedback crystal cavities for x-ray lasers.

The strong interest in the coherent generation and guiding of x rays is well known. Many papers have recently appeared treating different concepts of stimulated x-ray emissions, 1-3 and x-ray guiding in thin films was achieved. 4 Crystals were suggested as end reflectors to generate feedback.' Here we suggest a different type of cavity using zeolite crystals that would guide the emitted x-rays ...

Optimum driving a Z-pinch for soft X-Ray lasers

A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...

X-ray resonance in crystal cavities: realization of Fabry-Perot resonator for hard x rays.

X-ray back diffraction from monolithic two silicon crystal plates of 25-150 microm thickness and a 40-150 microm gap using synchrotron radiation of energy resolution DeltaE = 0.36 meV at 14.4388 keV clearly show resonance fringes inside the energy gap and the total-reflection range for the (12 4 0) reflection. This cavity resonance results from the coherent interaction between the x-ray wave fi...

Evolution of X-ray cavities

A wide range of recent observations have shown that AGN-driven cavities may provide the energy source that balances the cooling observed in the centres of “cool core” galaxy clusters. One tool for better understanding the physics of these cavities is their observed morphological evolution, which is dependent on such poorlyunderstood properties as the turbulent density field and the impact of ma...
