2. outline LWFA Generation of e-beams Generation of light sources
Harnessing of electron and light sources – oncology & medical imaging

3. Laser plasma wakefield accelerator vs conventional accelerator
LWFA
Conventional accelerator
Switching the medium
Switching the driving frequency
RF cavity (100s m)
plasma cavity (few mm)
microwave freq.
light freq.

4. LWFA max. acceleration gradient : 100 GeV/m e-beam properties:
emittance < 1 π mm mrad
energy spread < 0,5%
tunable

5. X-rays
Plasma wiggler
(betatron radiation)
Undulator

6. Medical applications electorns harnessing e-beam to oncology
tuneability
injection control
plasma density
laser properties: pulse lenght, intensity, aₒ

7. light sources from e-beam
Medical applications
light sources from e-beam
medical imaging
(Pase Contrast Imaging)
radioisotope generation 15 MeV – 25 MeV
i.e. 109 photon/s on Carbon target -> 2 x C nuclei
11C: labelling molecules in positron emission tomography (PET)
Tuenability:
UNDULATOR:
- e energy
- undulator periods
- B-field
PLASMA WIGGLER
- plasma density
- laser intensity
Copper wires from 20 to 100 mm
