The pulse-by-pulse X-ray beam monitor equipped with microstripline structure had been developed at SPring-8. This monitor has a potential to function as (1) a pulse intensity monitor, (2) a pulse-by-pulse X-ray beam position monitor (XBPM), and (3) a pulse timing monitor. In insertion device beamlines, however, it cannot be used without further improvement because of heat-resistance problem. Therefore, we examined a pulse-by-pulse XBPM for insertion device beamlines by introducing heat resistance structure, which employed a diamond heat sink. Thermal finite element analysis was carried out to design an effective structure of a detector head and the holder. Evaluation tests of the prototype will be also presented in this contribution.
