SUMMARY:Overview of TAE Technologies’ Norman/C-2W Field-Reversed Con
 figuration Experiments\, Plasma Physics (Physics/ECE/NE 922) Seminar\,
  Hiroshi Gota\, TAE Technologies
DESCRIPTION:TAE Technologies (formerly named “Tri Alpha Energy”) i
 s based out of state-of-the-art plasma
\nresearch facilities in Califo
 rnia. Over the last 20 years\, TAE has continued to build on our early
 
\ntechnology and evolve our advanced beam-driven field-reversed confi
 guration (FRC) approach to
\nrealize/develop a commercially competitiv
 e clean fusion energy. An FRC is a prolate compact
\ntoroid (CT) that 
 has many attractive features such as extremely high β value\, simple

 \naxisymmetric geometry\, unrestricted natural divertor\, and potentia
 lly enabling the use of
\nadvanced\, aneutronic fuels. The newly const
 ructed C-2W experimental device (also called
\n“Norman”) is the wo
 rld’s largest CT device and has the following key system upgrades fr
 om the
\npreceding C-2U device: (i) higher injected power\, optimum an
 d tunable energies\, and extended
\npulse duration of the neutral-beam
  injection (NBI) system\; (ii) installation of inner divertors with
\n
 upgraded edge-biasing systems\; (iii) fast external equilibrium/mirror
 -coil current ramp-up
\ncapability\; (iv) installation of trim/saddle 
 coils for active feedback control of the FRC plasma\;
\nand (v) extens
 ive upgrade/expansion of plasma diagnostic capability. C-2W has produc
 ed
\ndramatically improved initial FRC parameters (good target for eff
 ective NBI)\, thus producing
\nbetter FRC performance overall compared
  to C-2U\; e.g. higher temperatures (initially and later in
\na discha
 rge)\, longer lived plasmas. This talk will review highlights of the C
 -2W program as well
\nas recently obtained experimental results.
