Advanced Concepts for Photon Sources. Volume 3. Beam Excited Plasma Radiator.

摘要

The large total energy and power levels available in relativistic electron beams make them an attractive candidate for heating high density or large volume plasmas. If the plasma density is greater than a few times 10 to the 16th power/cc, then a significant fraction of the energy transferred to the plasma will be radiated in times of the order of 100 nsec. By choosing the atomic number and electron temperature of the plasma, most of this radiated energy can be soft X-rays. The problem posed by the beam-plasma radiator approach is whether the conditions for energy transfer, plasma containment, high density, and high plasma electron temperature (1 to 10 keV) can all be satisfied simultaneously.
