Target 4 Flight Path 90L (TPC)
Target 4 Flight Path 90L is primarily used for fission cross section measurements. The flight path length is approximately 7 to 15m long. Instruments used on this flight path have included fission chambers and the fission Time Projection Chamber (TPC).
Fission chambers placed on FP90L have been used to measure cross-sections, yields, and total kinetic energy of fission fragments. The fission TPC is used to measure energy-differential neutron-induced fission cross-sections with unprecedented precision. The Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) collaboration, comprised of scientists and students from six universities and four national laboratories, has developed this novel detection system, a permanent fixture on FP90L.
