Experiments on semiconductor systems using a pulsed-field-magnet free-electron-laser combination

Conference item

The FELIX free-electron laser is continuously tuneable over the wavelength range 5-100 mu m and can provide great power and the possibility of time-resolved experiments in the ns to mu s range. We describe a pulsed magnet specifically designed for semiconductor experiments using FELIX, which provides fields of up to 45 T, with a pulse-shape tailored to the macropulses of the FELIX source. The magnet consists of a conventional outer coil providing fields of up to 30 T with a pulse length of several ms, plus a single-layer inner coil with a rise-time of similar to 10 mu s, matched to duration of the FELIX macropulses. The magnet is to be extended to fields of up to 60 T. (C) 1998 Elsevier Science B.V. All rights reserved.
