Measurement of Decay of Radioactive and Isomer Nuclei by Spatial and Time Coincidence in the Timepix Pixel Detector

Popis výsledku v původním jazyce

The high granularity of the pixel detector allows applying not only temporal but also spatial coincidence technique for background suppression. This is particularly important for scarcely populated nuclei and/or detection under high rate of unwanted/background events. For these different situations two methods were developed using a segmented ionization chamber as trigger: (i) a time-delayed opening (start) of the detector shutter, and (ii) a trigger-driven external clock with varying time delay with the detector shutter open. For these approaches, Timepix was operated in its time mode and in its time-over-threshold mode, respectively. The methods are demonstrated on the detection and decay measurement of 8He and 6He ions as well as of the 7.6 ?s 496.2keV isomer 98mY, respectively.
