Experimental techniques

Scientific experiments in STCs are challenging but feasible. The main handicaps are the short pulse duration, the induced electric fields near the coil and the electromagnetic noise caused by the discharge of the capacitor banc. Thanks to the tremendous evolution of fast electronics and opto-electronics throughout the past decades, a number of experimental techniques have nevertheless been adapted to STCs. At present, optical experiments using single-element detectors can be performed in several wavelength ranges between 400 nm and 11 μm. Another well-established technique are magnetization measurements making use of compensated pick-up coils.

Current developments at the LNCMI are mainly aiming at the improvement of optical measurements in two respects: an extension of the available wavelength range close to the THz-regime, and the use of detector arrays in the visible and near-infrared.
