说它是相干的,因为聚束中电子是相干发光的(coherent radiation),即他们发射的光场强度正比于电子数目的平方( I_{rad}\propto N_e^2 )。而通常的未聚束的电子发光强度则是线性正比于电子数( I_{rad}\propto N_e )。这也就是FEL中自由电子为什么要被聚束的主要原因,可提高发光强度。 另一方面,这还只是经...

photon, minute energy packet of electromagnetic radiation. The concept originated (1905) in Albert Einstein’s explanation of the photoelectric effect, in which he proposed the existence of discrete energy packets during the transmission of light. Earlier (1900), the German physicist Max Planck had ...

Radiation exposure due to the detonation of an improvised nuclear device remains a major security concern. Radiation from such a device involves a combination of photons and neutrons. Although photons will make the greater contribution to the total dose,
While for photon radiation hypofractionation has been reported to induce enhanced immunomodulatory effects, little is known about the immunomodulatory potential of carbon ion radiotherapy (CIRT). We thus compared the radio-immunogenic effects of photon and carbon ion irradiation on two murine cancer cell...
