Polarization of Bremsstrahlung

Description: Abstract: Numerical information necessary to an experimental study of the polarization of bremsstrahlung is presented. One may conclude that it is possible to produce significantly polarized γ-ray beams with existing electron accelerators. These beams will provide a new tool for the study of photonuclear reactions over a wide range of energy.

Theoretical Investigation Based on Experimental Frequency-Response Measurements of an Automatic Altitude Control in Combination With Supersonic Missile Configuration

Description: Report presenting an analysis of an investigation of a simple altitude control based on static-pressure and rate-of-climb sensing is combined with a supersonic missile as a servomechanism to yield the closed-loop behavior of the entire system. The control system was found to function successfully at a low-altitude missile of the boost-guide type and would likely perform well at high altitude.
