NA Geometry

Updated 6-Jan-2006 The full report by Tim Ngo, which provides the internal geometry of the neutron detector, as well as the position of the detector in the Hall.

Here is also a link to Tim Ngo's website.

In the Run database (currently the db_run.dat file) the position of the neutron detector is specified by the location (angle wrt to the beamline, distance from the Hall center) of the plumb-bob at the front of the Neutron Detector.
