TP34: POWGEN3: A High Resolution Third Generation Powder Diffractometer

J.P. Hodges (Spallation Neutron Source, Oak Ridge National Laboratory)

POWGEN3 is a fundamental departure from previous designs for a powder diffractometer at a spallation neutron source. POWGEN3 may be considered the world’s first third-generation time-of-flight powder diffractometer. For the first time, a high-resolution powder diffractometer is able to take advantage of a high source repetition rate. Combined with a supermirror neutron guide system, POWGEN3 is a very efficient instrument. The high count rates thus achieved together with high-resolution characteristics present a big leap forward in performance over previous diffractometer designs. POWGEN3 will thus provide unprecedented opportunities for new science in the study of crystalline materials.
