Gas target studies at the Naval Postgraduate School linear accelerator.

Abstract

A study of the parameters involved in electron scattering experiments with gaseous targets at the Naval Post- graduate School Linear Accelerator v/as conducted. The parameters included gas densities, effective target thicknesses, and radiative corrections to experimental cross-section calculations. To compare the NPGLINAC with other accelerators an electron scattering experiment was performed, using a hydrogen-helium gas mixture target, at values of q^ from 0.10 to 0.55 F~2. The resulting charge form factor for helium was fairly consistent with previous experimental models.; however, it was concluded that experiments using separate gas targets yield greater accuracy than those using a gas mixture.
