Second half of NIAC is to run codes concurrently• synchronize neutron population vs. time• Optimize energy output
- As function of geometry- As function of composition
– Mix of UF6, D‐T– Lithium liner thicknesses

• Gasdynamic nozzle performance to be compared with magnetic nozzle to assess loss mechanisms in magnetic nozzles, e.g.
• Field/plasma instabilities
• Plasma detachment
Direction of current
Single turn Magnetic Nozzle
Marshall Space Flight Center
Charger ‐ 1
A test facility for high power and thermonuclear fusion propulsion concepts, astrophysics modeling, radiation physics
Located in the UAH AerophysicsLab at Redstone
The highest instantaneous pulsed power facility in academia – 572 kJ (1 TW at 100 ns)
Marshall Space Flight Center
Long Range Plans
NIAC Phase II• Complete Charger 1 refurb• Ignite PuFF plasma• Continue magnetic nozzle research
Charger II• Construct breadboard PuFF system capable of 10‐20 Hz operation
- Upgrade to flightweight hardware – NASA- Optimize pulse for maximum power output – DOE- Astrodynamics, radiation protection, other research goals ‐ Various
