NCMART (normalized continuous multiplicative algebraic reconstruction technique) is a modification of the algebraic reconstruction technique first used in tomography. It is applied to two-dimensional spatial resolution of spectroscopic data from the ELMO Bumpy Torus (EBT) taken in two fan views from ports at the top and side of the midplane of a mirror section. The reconstruction algorithms are derived and a description is given of the code implementing them for the EBT data on a PDP-10 computer. Test problem results show that reliable information on impurity distributions in the cross section viewed may be obtained by this method. Instructions for use of the computer codes are included, along with source program listings and sample output from a run using experimental data.
