Outline of Final Research Achievements

We have developed a pulse-by-pulse X-ray beam position monitor for a synchrotron radiation beamline. In order to make it realized, it is necessary to enhance not only high frequency properties but also heat resistance. Therefore, we devised the original detector head equipped with a diamond film for a heat sink. We installed the prototype in a frontend of a bending magnet beamline and carried out performance tests. As a result, we found that a signal for this monitor has a unipolar pulse with the pulse length of less than 1 ns FWHM (full width at half maximum), which is our targeted value.
