1. A flat response position sensing neutron detector for use in the collection of neutron spectroscopic data comprising:

  • (a) detection means located in a housing, said housing having first and second ends;

    (b) first neutron moderation means surrounding said housing except for said first end defining an open end in said first neutron moderation means;

    (c) neutron shield means surrounding said first neutron moderation means except for said open end in said first neutron moderation means;

    (d) position sensing measurement means disposed at said first and second ends of said housing and connected to said detection means for determining the relative distance from said housing first end at which neutrons are detected, wherein neutrons enter said detection means exclusively through said open end to be moderated and sensed upon reaching thermalization level; and

    (e) means to determine the energy levels of the detected neutrons from information of the sensed positions of said neutrons.
