Neutron production and detection on the TFTR Tokamak during DT operation

The Tokamak Fusion Test Reactor (TFTR) has performed initial high-power experiments with deuterium and tritium fuelling as nominally equal densities. During the deuterium-tritium experiments, neutron emission rates and yields were measured with U and U fission chambers, silicon surface barrier diodes, a scintillating fiber detector, spatially collimated He proportional counters and ZnS seintillators, and a variety of elemental activation foils. The sensitivities, configuration and calibration of the different systems are compared.
