The present invention relates to a beam analyzing system and a method for analyzing pulsed particle or laser beams. A first power switch selectively conducts current from a VCM node to a power supply node, and a second power switch selectively conducts current from the VCM node to a power return node. In some embodiments, fluorinated carbon nanotubes are reacted with mono-metal salts of a dialcohol, MO\u2014R\u2014OH, where M is a metal and R is hydrocarbon or other organic chain andor ring structural unit.
