AN IMPROVED NUCLEAR DENSITY GAUGE. Period covered: July 1 to August 1, 1959
Development of a nuclear density gage is reported. A diation transmitted through a sample and through a calibrated wedge. In simple cases the two radiation beams are mechanically chopped at 60 cycles, and the difference in intensity activates a servosystem which repositions the wedge until balance is achieved. Development or a lead chopper for use with Tm/sup 170/ is reported. The commutating system described previously was completed and is being tested. Research has begun on the use of mechanical energy discrimation in gaging. (J.R.D.)
