Abstract
A surface analyzer for analyzing the atomic composition of the surface of sample. An ion source generates a proton beam. A magnet directs the proton beam through an accelerating device toward the sample for collision therewith. Protons that are scattered at an angle of 180.degree. pass through the accelerating device in the reverse direction and are decelerated. The magnet directs the protons as a parallel beam to a position detecting device that indicates the position at which the proton beam strikes and energy loss of the protons can be determined.
