Dense Plasma Focus
Plasma Physics
kJ (Capacitor Energy) & Short Pulses (ns)
A pulsed plasma device that uses electromagnetic forces to accelerate and pinch a plasma column into a short-lived, high-density hot spot.
E_k ~ 10–100 kJ (Electromagnetic Acceleration and Pinch)
Divertor
Plasma Physics
MW/m² (Heat Flux Capacity)
A component in a fusion tokamak that uses magnetic null points (X-points) to extract helium ash and heat exhaust from the plasma edge.
Magnetic X-point Separatrix Boundary Geometry
Dusty Plasma
Plasma Physics
μm (Dust Size) & Charged State
A complex plasma containing solid nanometer-to-micrometer scale dust grains that collect high negative charges from surrounding plasma electrons.
