From discussions with the EFDA-JET Task Forces in early 2000, a range of requirements emerged for higher spatial resolution Te and ne Thomson scattering measurements in various specific regions of JET plasmas. These requirements are summarized in table 1 and seek significantly better spatial resolution than is achieved or is achievable with the two LIDAR Thomson scattering systems1,2 currently working on JET (4Hz core LIDAR ∼12cm; 1Hz Edge LIDAR 2–3cm, outer ∼10cm only). Two High Resolution Thomson Scattering (HRTS) proposals were received from the Associations, one from C J Barth, (FOM)3 and one from P Nielsen and R Pasqualotto, (RFX)4. These, in their final form, used almost identical “90 degree” scattering geometry (see figure 1).
