Conventional XBPMs work in the direct-current (DC) mode, because it is difficult to measure a beam position in the pulse mode under the sever heat load condition. The key point of the design is aiming at improving heat-resistance property without degradation of high frequency property . This monitor is equipped with microstripline structure for signal transmission line to achieve pulse-by-pulse beam position signal. A photocathode is titanium electrode that is sputtered on a diamond heat sink to achieve high heat resistance. We have manufactured the prototype, and demonstrated feasibility at the SPring-8 bending magnet beamline. As a result, we observed a unipolar single pulse with the pulse length of less than 1 ns FWHM and confirmed that it has pulse-by-pules position sensitivity . Furthermore, this monitor can be also used in the direct-current mode with good stability and good resolution. The operational experience will be also presented.
