Abstract

Systems and methods for that utilize a compressed coherent high intensity X-ray pulse to drive acceleration of particles in a solid medium laser wakefield accelerator (LWFA).

First claim

What is claimed is:

1. A method of laser wakefield acceleration in a solid media regime comprising the steps of injecting an X-ray pulse into a solid medium with one or more nanoholes there through, and accelerating particles in the solid medium through wakefield acceleration.

2. The method of claim 1 wherein the solid medium is a metallic plasma.

3. The method of claim 1 wherein the solid medium is a crystal.

4. The method of claim 1 wherein the X-ray pulse is a compressed coherent high intensity X-ray pulse.

5. The method of claim 4 further comprising the step of generating the compressed X-ray pulse from a compressed optical laser pulse, wherein the compressed X-ray pulse has an intensity 1 to 3 orders of magnitude greater than an intensity of the optical laser pulse and a pulse duration 1 to 3 orders of magnitude smaller than a pulse duration of the optical laser.

6. The method of claim 5 wherein the step of generating the compressed X-ray pulse includes pulse compressing the compressed optical laser.

7. The method of claim 6 further comprising the step of generating the compressed optical laser.

8. The method of claim 7 wherein the pulse duration of the compressed optical laser is in the 10 0 fs scale.

9. The method of claim 8 wherein the pulse duration of the compressed X-ray pulse is in the 10 0 as scale.

10. A method of laser wakefield proton acceleration in a solid media regime comprising the steps of
injecting protons into a solid medium,
injecting an X-ray pulse into the solid medium with one or more nanoholes there through, and
accelerating the protons in the solid medium through wakefield acceleration.

11. The method of claim 10 wherein the solid medium is a metallic plasma.

12. The method of claim 10 wherein the solid medium is a crystal.

13. The method of claim 10 wherein the protons are injected from a thin foil.

14. The method of claim 13 wherein the X-ray pulse is a compressed coherent high intensity X-ray pulse generated from a compressed optical laser pulse.

15. The method of claim 14 further comprising the steps of illuminating the thin foil with the compressed X-ray pulse and then illuminating the solid medium with the compressed X-ray pulse generating a metallic plasma wave that accelerates the protons.

16. The method of claim 14 further comprising the steps of illuminating the thin foil with the compressed optical laser pulse and then illuminating the solid medium with the compressed X-ray pulse generating a metallic plasma wave that accelerates the protons.

17. The method of claim 16 further comprising the step of generating the compressed X-ray pulse from a compressed optical laser pulse, wherein the compressed X-ray pulse has an intensity 1 to 3 orders of magnitude greater than an intensity of the optical laser pulse and a pulse duration 1 to 3 orders of magnitude smaller than a pulse duration of the optical laser.

18. The method of claim 17 wherein the step of generating the compressed X-ray pulse includes pulse compressing the compressed optical laser.

19. The method of claim 18 further comprising the step of generating the compressed optical laser.

20. The method of claim 19 wherein the pulse duration of the compressed optical laser is in the 10 0 fs scale.

21. The method of claim 20 wherein the pulse duration of the compressed X-ray pulse is in the 10 0 as scale.

22. The method of claim 17 wherein the pulse duration of the compressed optical laser is in the 10 0 fs scale.

23. The method of claim 22 wherein the pulse duration of the compressed X-ray pulse is in the 10 0 as scale.
