high energy density plasma is a plasma with pressure above 1 MBar

[math]1 MBar = 1 \times 10^6 \times 10^5 Pa = 10^{11} Pa = 10^{11} (N m)/(m^2) = 10^{11} J/m = 10^{11} (10^7 erg)/(10^6 cm^3) = 10^{12} erg/cm^3[/math]


magnetic field produced by single wire (Biot-Savart Law)

[math]B[G] = 0.2 \times I(A) / r(cm) [/math]
[math]B[T] = 0.2 \times I(kA) / r(mm) [/math]
  • 10 MA at 4 mm radius is 500 T
  • 100 kA at 40 um radius is 500 T
  • 160 kA at 5 um radius is 6,400 T

magnetic pressure

[math] P_m(bar) = 4 \times B(T)^2 [/math]
[math] P_m(bar) = 0.16 \times I(kA)^2 \times R(mm)^{-2} [/math] 
  • 10 MA at 4 mm radius is 1 MBar
  • 100 kA at 40 um radius is 1 MBar
  • 160 kA at 5 um radius is 164 MBar

Bennett condition

  • magnetic pressure = plasmakinetic pressure
  • 100 kA at 40-um radius is 1 MBar of plasma pressure
  • 100 kA at 1-um radius is 1.6 GBar of plasma pressure
