high energy density plasma is a plasma with pressure above 1 MBar
magnetic field produced by single wire (Biot-Savart Law)
- 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
- 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
- 14 MBar at 140 kA at 15-um radius (shot 634 with 2x30-um W wires)
- 25 MBar at 150 kA at 12-um radius (shot 657 with 2x30-um Mo wires)
- 100 MBar at 154 kA at 6-um radius (shot 657 with 2x30-um Mo wires)
