| Zusammenfassung: | A fast multigrid ion chamber for the detection of fluorescent X-rays has been developed. The structure of 17 grids with close separation was employed to maximize the time response as well as to give sufficient detection efficiency. The measured rise/fall response time to cyclic X-rays was shorter than that of an existing three-grid ion chamber by more than one order of magnitude. A 0.13 ms time response was obtained at the 500 V applied voltage, where the detector can stably operate without any discharge. The available frequency range is as high as 1 kHz with a practical amplitude response |
