Description: 

Atomic beam apparatus for determining certain properties, known as spins and magnetic moments, of nuclei of radioactive atoms. A stream of neutral atoms is directed down the axis of the machine, the thick cyclinder (partially hidden by supporting equipment) reaching from upper right to left center. The atoms pass through the gaps of different types of magnets and are subjected to a radiofrequency magnetic field. From the deflection of the stream of atoms one can determine certain magnetic characteristics of nuclei--the spin and magnetic moment. The beam is allowed to deposit for an arbitrary time interval on a tungsten foil which can be removed from the apparatus and its radioactivity counted externally. This serves as a measure of the beam intensity. In this photo taken at Brookhave National Lab, Upton, New York, one of the tungsten targets is being inserted into a ramrod which can be pushed through an airlock system into the high vacuum detecting position.
