Abstract
To perform thermal cross section measurements the low energy neutron i ntensity from the RPI linac facility was increased. A new Enhanced The rmal Target (ETT) was designed, constructed and tested. The thermal fl ux of the new target was up to sis times greater than the nux from the previous RPI Bounce Target (BT). This additional gain allows transmis sion measurements to be performed in the energy range of 0.001 to 15 e V with high statistical accuracy in a short time (similar to 40 h). Th e ETT was also designed to be coupled to a cold moderator that will gi ve an additional flux increase factor of about 9 below 3 meV. Design c alculations for the cold moderator including neutronics and cryogenics are also given.
