  • Note that RP and setpoint values are listed in the shot_list.data file

A. (TOP) The PD probe head's porthole of the tokamak, as well as the central axis of the reciprocating probe arm, lies along the R-axis. The base of the RP has its center or origin as indicated. All PD Channel collimator entrance offsets are measured from this origin. (BOTTOM) The base of the RP lies along the R-axis.

B. (TOP) Looking at the poloidal cross section of the tokamak, of the PD head yields the following Z-axis and R-axis, with the Y-axis going into the page. (BOTTOM) The horizontal displacements along the R-axis between the entrance of each Channel's collimator to the base of the RP (as defined in Figure Set 3.A.).
