The picosecond electrical pulse-propagation characteristics of microchannel-plate detectors, used in diagnosing laser-driven inertial-confmement-fusion experiments, were measured with an electro-optic sampling system. We determined propagation velocity and signal distortion of the microchannel-plate microstrip, as well as its characteristic impedance and the substrate relative dielectric permittivity. These parameters are critical for proper calibration of the detectors and serve as a guide for their improved designs.

    Solid-state nuclear track detectors, such as CR-39, are widely used in physics and in many inertial confinement fusion (ICF) experiments. In the ICF experiments, the particles of interest, such as D3He-protons, have ranges of order of the detector thickness. In this case, the dynamic range of...
