MOTION CONTROL: Automated alignment keeps Z machine on target

Computer-controlled motorized mirror mounts enable rapid realignment of beam-steering optics between discharges at Sandia National Labs' Z machine.
FIGURE 1. A basic field-effect transistor consists of a source and drain of charge carriers that connect to a channel controlled by a gate (top). A fundamental standing-charge-density oscillation, known as a plasmon, sloshes between two boundaries (bottom left). Increased current causes a higher harmonic of the fundamental plasmon, splitting the group in two (bottom right). Like a spring constant, increasing the carrier density in the channel increases the resonant frequency.
