Diagnostic Capabilities provided by an Ultra-Fast Multi-Wavelength Pyrometer

Abstract

Multi-wavelength pyrometry is the only experimental diagnostic able to measure high temperatures in Warm Dense Matter experiments on a nanoseconds timescale. An ultra-fast 5-channel pyrometer was built and tested on a set of metals in ion heating experiments at GSI. In addition to temperature measurements the set-up allows a further characterization of the shape and duration of the beam pulse
