| 摘要 |
The invention relates to a photon source comprising an electron cyclotron resonance (ECR) multicharged ion plasma source which comprises a cylindrical plasma vacuum chamber (CH) , an injection guide (GD) for injecting microwaves into the chamber, a device (I) for injecting a gas into the chamber, a pumping system (P) to extract ionised gas resulting from the action of microwaves on the gas (g) , and a cylindrical magnetic structure (1, 2, 3a, 3b, 4) that surrounds the chamber (CH) and that produces at least two closed surfaces (S) in line along the chamber axis and on which the value of the magnetic field is equal to the value of the electron cyclotron resonance field (ECR) , the photons being extracted through an opening (02) in line along the axis of the chamber . |
