THE GENERATION AND APPLICATION OF MEGAGAUSS FIELDS AT THE HUMBOLDT HIGH MAGNETIC-FIELD CENTER

A new multi-megagauss generator has been constructed which produces 23 9 and 311 T with a pulse duration of 5 mu s 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 an d the galvanic separation of control panels and high-voltage units. Th e installation is designed as a scientific instrument including suitab le cryostats, fast data acquisition systems and basic setups for spect roscopical investigations. The design and performance of the field gen erator as well as the supplementary equipment are discussed and demons trated in connection with cyclotron resonance measurements at temperat ures down to 5 K.
