Neutron generators, both D--D and D--T, have been used to calibrate the TFTR neutron activation (NA) system for point sources located within the tokamak. The foils used were In for D--D neutrons and Cu, Al, and /sup 238/U for D--T neutrons. Delayed neutrons following fission were counted when using /sup 238/U foils, 336-keV ..gamma.. rays from /sup 115/In(n,n')/sup 115//sup m/ In reactions, annihilation radiation from /sup 62/Cu following the /sup 63/Cu(n,2n)/sup 62/Cu reaction, and 1368- and 2754-keV ..gamma.. rays from the /sup 27/Al(n,..cap alpha..)/sup 24/Na reaction. Large effects caused by source anisotropy and local machine structure were observed. These effects and the attempts to accommodate them in the data analysis will be described.
