Beam optics and magnet technology of the microtron in mainz
Abstract A description is given of the beam transport system for injection into the first microtron of MAMI. Further, a special procedure to improve the field distribution of the dipole magnets is described in some detail and results are given.
Enhancement of the linear polarization of coherent bremsstrahlung by collimation of the photon beam
A method is described to precisely predict the relative intensities and degrees of linear polarization of coherent bremsstrahlung from diamond crystals, taking into account the collimation of the photon beam and the lateral distribution and angular divergence of the electron beam in addition to the properties of the crystal. It is confirmed that the increase of the degree of linear polarization through collimation of the photon beam is a sizable effect. Compared to previous approaches considerable progress has been made in reproducing the experimentally observed relative intensities of collimated coherent bremsstrahlung, by taking into account the angular distribution of coherent bremsstrah…
