A method for pulsed neutron well logging of a subsurface formation, includes irradiating the formation with a plurality of bursts of neutrons of a group of selected durations; detecting gamma rays resulting from interaction of the neutrons during a group of selected time gates which contains at least some early and late gamma ray counts. The deck defines a plurality of first through-holes and the pattern plate defines a plurality of second through-holes aligned with the first through-holes. The display system has a light control medium for controlling directivity of the light illuminated on the display. The energy management policy and energy usage is also compared. The absence of inductive coupling between the loop elements provides a frequency-independent means for multiplexing signals for transmission and reception by the multiple loop antenna system. The compression resistant plate is bonded to an inner surface of the metal plate and spans the opening.
