Neutron Radiation Effects Testing facilities at LANSCE: ICE Houses
The shape of the neutron spectra on the 30o flight paths at the Weapons Neutron Research (WNR) facility at LANSCE are very similar to the neutron spectrum produced in the atmosphere by cosmic rays but with a neutron flux of over a million times higher. This large flux allows testing of semiconductor devices at greatly accelerated rates. There are two flight paths devoted to neutron radiation-effects testing: ICE House and ICE-II. The ICE House is located at 30o to the left of the proton beam and ICE-II is located at 30o to the right of the proton beam. Both provide a cosmic-ray like neutron spectrum.
ICE II Flight Path 30R
Irradiation of Chips Electronics (ICE II) is located on the 30° right flight path at LANSCE/WNR. At this angle, the shape of the neutron spectrum is very similar to that of neutrons produced in the atmosphere by cosmic rays but with a neutron flux that is over a million times higher. This large flux allows testing of semiconductor devices at greatly accelerated rates. Companies from around the world can use this facility to characterize components and study various failure modes caused by terrestrial neutron radiation. Detailed use of these flight path is described in the Radiation Effects and Electronics Testing handbook at the below link.
