Abstract

A new multi-megagauss generator has been constructed which produces 239 and 311 T with a pulse duration of 5 μs in single turn coils with an inner diameter of 10 and 5 mm, respectively. Prominent features of the installation are the vertical coil orientation, a stripline-based lightweight/low inductance discharge circuit in modular arrangement and the galvanic separation of control panels and high-voltage units. The installation is designed as a scientific instrument including suitable cryostats, fast data acquisition systems and basic setups for spectroscopical investigations. The design and performance of the field generator as well as the supplementary equipment are discussed and demonstrated in connection with cyclotron resonance measurements at temperatures down to 5 K.
