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.

SBS Shift Information

If you are on shift and the DAQ is not working, go to Fixing the SBS DAQ

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.

Figure 1. Expected results of GEn at the planned kinematics along with projected uncertainties.

GEn Kinematics Spreadsheet (Excel)

The proposed kinematic points for GEn are given here in Figures 2-4.
