Query: Study of Beam Energy Spectrum Measurement in the NLC Extraction Line   The NLC extraction line provides a secondary focal point with a low beta
function and 2 cm dispersion which can be used for measurement of the beam
energy spectrum. In this study, tracking simulations were performed to
transport the 0.5 TeV electron beam from the Interaction Point (IP) to the
secondary focus (SF), ``measure'' the resultant transverse beam profile and
reconstruct the disrupted IP energy spread. In the simulation, the obtained
energy spectrum reproduced the initial IP spread reasonably well, especially
with the vertical dispersion at SF which provides larger ratio of dispersion to
the betatron beam size.
