Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

l30 Monbusho: Ministry of Education, Science and Culture, Japan, after its Japanese acronym. Neutral-beam injection: Heating of contained plasma toward ignition by injection of beams of energetic (typically greater than l00 thousand electronvolt) neutral atoms, which can cross the magnetic lines of force but which are later ionized in the contained plasma, thus being themselves contained.
