Electron and Proton Beam Diagnostics with Synchrotron Radiation

Synchrotron radiation is widely used to measure the cross-section of the electron beams. Large photon fluxes within a convenient part of the spectrum are radiated by the electrons in the bending magnets. To obtain sufficient intensities of visible light from high energy protons, there are special magnets needed which alter the normal spectral distribution of the radiation. The resolution of the cross-section measurement is limited by diffraction. This limit can be improved by working with a short wave length or by using the radiation from short magnets.
