Welcome to the SBS Shifters Wiki!

The purpose of this Wiki is to organize information relevant to the running experiment and is intended to be the "one stop shop" for all things shift-related. This includes things like run plans, shift sign up, safety, How Tos, important links, concise documentation of equipment (single page of key information for a subsystem encouraged) as well as trouble-shooting and data quality information. Information not directly relevant to shifters should be stored elsewhere such as the SuperBigBite Wiki. For more information, see the GEn webpage or the SBS website.

GEn Physics

The GEn experiment is determining the electric form factor of the neutron to high Q² by measuring the ratio of the electric form factor of the neutron to proton via recoil polarimetry. The planned kinematic points have changed slightly from the original proposal; however, the impact of these measurements remains intact. The new kinematics are shown Figure 1 along with the expected uncertainty compared to the originally proposed kinematics. These error bars include current estimate of target and datector performance.
