Claim 0:
1. An apparatus for measurement of Thomson scattering signals from a plasma, the apparatus comprising:
a light emitting device, configured to emit a light beam into the plasma along as axis, where at least a portion of the light beam is scattered by the plasma;
a light collector comprising a collection surface situated at an angle relative to the axis and configured to collect the Thomson scattering from the plasma, wherein the Thomson scattering diverges from the axis of the light beam as the Thomson scattering contacts the light collector at a collection angle less than 90 degrees from the axis of the light beam whereby a spectral linewidth of the Thomson scattering is decreased; and
a sensor assembly to detect the Thomson scattering.
