Nuclear excitations and the XFEL XFEL
![Page 4: Nuclear Physics Type talks 1 ) Adriana Gagyi-Palffy 2) Ken Ledingham 3) Fred Hartmann](https://reader036.vdocuments.us/reader036/viewer/2022062813/568164f6550346895dd761e7/html5/thumbnails/4.jpg)
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?

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

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

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
