Abstract
The measurement of the neutron electric form factor, G$$n\atop{e}$$, will allow us to solve indirectly for the quark charge distribution inside of the neutron. With the equipment at Jefferson Lab we have measured G$$n\atop{e}$$ at four momentum transfer values of Q 2 at 1.3, 2.4 and 3.4 (GeV/c) 2 using a polarized electron beam and polarized Helium target. The scattered electrons off of the Helium target are detected in the BigBite spectrometer and the recoiling neutrons from the Helium are detected in the Neutron Arm, which is composed of an array of scintillators. The main focus of this thesis will be devoted to the geometry, timing and energy calibrations of the Neutron Arm.
