Abstract
A uniform cryogenic layer of DT fuel is maintained in a fusion target having a low density, small pore size, low Z rigid foam shell saturated with liquid DT fuel. Capillary action prevents gravitational slumping of the fuel layer. The saturated shell may be cooled to produce a solid fuel layer.
Claims10
An inertial confinement fusion target comprising a hollow spherical shell of low density, low Z, open cell, rigid foam saturated with liquid DT.
A method of preventing gravitational slumping of a cryogenic layer of DT fuel in a fusion target comprising:
- forming a hollow spherical shell of low density, low Z, open cell rigid foam;
- saturating the foam shell with liquid DT.
