The FINeSSE Detector

Experimental results from the last five years showing that neutrinos oscillate and have mass have revolutionized how we think about neutrinos. This includes not only what their place is in the Standard Model, but also how we can use them to understand the universe. Can neutrinos also help us probe the smallest scales of matter, such as mapping out the spin structure of the nucleon? New high intensity beams and novel detection techniques have rekindled interest in neutrino scattering physics, allowing us to answer these questions. Described here is a detection technique for the FINeSSE experiment, designed to well measure low Q 2 , ν – p elastic scattering events, necessary to determine the spin carried by the strange quarks in the nucleon.
