Description

For the evaluation of impulse bit for pulsed-magnetic nozzle thruster, a thrust stand having high signal to noise ratio under large pulsed current conditions and high sensitivity with the impulse bit of micronewton-second has been developed. All electric components generating large pulsed current for the magnetic nozzle are on the arm of the torsional thrust stand, in order to suppress interactions between large current cables and/or between cables and vacuum chamber. The developed thrust stand has a minimum detection limit of 3 μNs. The impulse bit of magnetic nozzle with laser produced carbon plasma was successfully measured as 𝐼𝑏=5.0±0.6 μNs with a laser energy of 520 mJ and a magnetic field strength of 0.53 T at the initial target position.
