H-1NF


The H-1NF is a research institute of the H-1 heliac, a large stellerator device located in the ANU Research School of Physics and Engineering at Canberra, Australia. It was established when the H-1 heliac was promoted to a national facility in 1996, adopting H-1NF as its facility name.

H-1 heliac stellarator

The H-1 flexible Heliac is a three field-period helical axis stellarator. Optimisation of the H-1 power supplies for low current ripple allows precise control of the ratio of secondary coil to primary coil currents, resulting in a finely tunable magnetic geometry. Slight variation in the current ratio between shots in a sequence corresponds to a high resolution parameter scan through magnetic configurations. The programmable control system allows for repetition rates of around 30 shots per hour, limited by data acquisition time and magnet cooling time.
