A new Thomson scattering measurement system, using a 1.064 mu m YAG laser a
s the radiation source, has been developed for the purpose of enabling meas
urement of electron properties to be made in glow discharge plasmas contain
ing reactive gases. Initial measurements made using the new system in an in
ductively coupled plasma gave results which were comparable with those obta
ined using previous Thomson scattering systems that used visible lasers.
