bridge the gap between nuclear excitation and photon energies...

T. Bürvenich, J. Evers and C. H. Keitel, PRL 96, 142501 (2006)

Nuclear excitations and the XFEL XFEL

What about the Petawatt laser?

Create the dense plasma for NEEC/NEET?

NEEC: to compare advantages of a dedicated electron target!

Help have an ion accelerator and XFEL at the same spot?

Will ELI provide ion accelerationand coherent x-rays or gamma-rays?

If yes, good enough for nuclear applications?

NIF? Plenty of electrons, photons, neutrons.

Can we model/analyze what is going on?

Conclusions

Combination of nuclear excitations in plasmas: trade-off between control and efficiency?

Driving of nuclear transitions via electrons or photons

NEECNEET

Isomer depletion – nuclear batteries?

STIRAP with nuclei

Cartoon of NEET/NEECKritcher et al LLNL

The theory is now sufficiently well understood that competing nuclear excitation by scattered electrons and direct photons can easily be calculated leaving NEET/NEEC experimental comparisons with theory meaningful

Sylvia talked about about electron acceleration up to about GeV in Wakefield acceleration and when coupled to either undulators or Betatron Emission mode promised monochromatic photons up to MeV levels

Nuclear waste reclassification

Storing radioactive waste at power stations

There are hundreds of thousands of such barrels world wide with very little knowledge of the contents. GRLSs would enable certifiable classification of the waste contents

Depository of hundreds of drums of radioactive waste

Antimatter creation (Positrons) using

Intense lasersVia

Bethe Heitler Process Z+e- =Z+2e- + e+

Trident Process Z+γ = Z+e- + e +

Using different thicknesses of targets

Although laser created positrons have been seen before Chris indicated that programs on

VULCAN and Gemini had not been successful. However what had

been learned could eventually lead to successful results in the future

with the counter-propogating beams in vacuum leading to

creation of antimatter
