A phase-space beam position monitor for synchrotron radiation
The stability of the photon beam position on synchrotron beamlines is critical for most if not all synchrotron radiation experiments. The position of the beam at the experiment or optical element location is set by the position and angle of the electron beam source as it traverses the magnetic field of the bend-magnet or insertion device. Thus an ideal photon beam monitor would be able to simul...
متن کاملPhase Analysis and Focusing of Synchrotron Radiation
High accuracy calculations of synchrotron radiation (SR) emitted by a relativistic electron show that the phase of the frequency domain electric field of SR differs from the phase of radiation of a virtual point source. These differences may result in the reduction of focusing efficiency of diffraction-limited SR, if the focusing is performed by conventional optical components optimised for poi...
متن کاملSynchrotron Phase Space Injection Into LEP
Although LEP was designed to allow both betatron and synchrotron injection, only betatron accumulation has been used up to now. During 1994 tests were made of injection in synchrotron phase space. Results are presented from these machine studies which show that for both 4 bunch and 8 bunch pretzel injection, this form of injection is a more efficient way of accumulating LEP beams. The use of sy...
متن کاملPhase objects in synchrotron radiation hard x-ray imaging
Phase objects are readily imaged through Fresnel diffraction in the hard x-ray beams of third-generation synchrotron radiation sources such as the ESRF, due essentially to the very small angular size of the source. Phase objects can lead to spurious contrast in x-ray diffraction images (topographs) of crystals. It is shown that this contrast can be eliminated through random phase plates, which ...
متن کاملDose fractionation in synchrotron radiation x-ray phase micro-tomography.
Phase sensitive x-ray imaging expands the applicability of standard attenuation based techniques by offering several orders of magnitude of increase in sensitivity. Due to the short wavelength, x-ray phase is not directly measurable, but has to be put in evidence by the use of phase contrast techniques. The phase can then be reconstructed from one or several phase contrast images. In this study...
