Neutron Polarimeters


There are two neutron polarimeters used in this experiment; one on the line and one on the line; giving us the ability to take data at two angles at one time. The detector on the flight line is the INPOL ( Indiana Neutron Polarimeter) detector and was originally built and used at LAMPF. When the polarized beam nuclear physics program was phased out at LAMPF the detector was moved to an upgraded facility at IUCF. A picture of the detector can be seen in figure gif.

The other neutron polarimeter was designed at Kent State University (KSU) specifically for use at IUCF. This work will discuss the KSU detector to some extent, but most of the effort will concentrate on the INPOL detector since that is the detector for which OSU shares responsibility.
