Abstract Text:
This presentation will summarize recent developments in the UW-Madison inertial-electrostatic confinement (IEC) fusion research program. Much of this UW-Madison research explores near-term applications of fusion energy. Recent advances in the understanding of gridded IEC plasmas include:
1) Characterization of the fusing-ion distribution f(E,r) along a line of sight using time-of-flight and coincidence counting of the DD reaction’s proton and triton.
2) Neutral particle analysis to characterize deuterium or helium.
3) Faraday cup analysis of negative ions beams in deuterium.
4) Development of an integral transport approach to atomic and molecular processes in helium {He, He+, He++} and deuterium {D2, D+, D2+, D3+, D-}.
5) Preparing to run high voltage (300 kV) experiments in He-3 plasmas.

Progress also has been made in the IEC Lab in
a) Understanding damage to hot materials, such as fusion reactor plasma-facing surfaces, when bombarded by helium.
b) Developing neutron sources for use in detecting clandestine materials, such as highly enriched uranium (HEU) or improvised explosive devices (IEDs).
c) Implementation of a 300 kV, 200 mA power supply.
d) Factor of ~4 expansion of lab space.

Characterization: 4.0
