First Scan for Q-weak Scanner
The Experimental Subatomic Physics Group at the University of Winnipeg performs research in the areas of nuclear and particle physics. The research program is focused on the fundamental structure and interactions of nucleons and hadronic systems and the use of nuclear physics to perform precision tests of the standard electroweak theory. A substantial part of the experimental program involves studies of parity violation in electron scattering from nucleons and nuclei. A program to exploit a new intense source of ultra-cold neutrons in Los Alamos will study the beta asymmetry in neutron decay with unprecedented precision as well as other fundamental properties of neutrons.
Image: (August 2, Jefferson Lab, Newport News, Virginia) The first successful scan for the Q-weak scanner. The scanner was completed and commissioned by Ms. Jie Pan and Mr. Peiqing Wang. The stripe of events across the top of the image are elastic electrons passing through the main detector and then being sensed by our Q-weak scanner. The data show the first successful scan taken by the Q-weak scanner. The scanner was constructed in our laboratory at the University of Winnipeg. Data were taken with our 0.89 mm Al target with a beam current of 5 microAmperes, and with the QTOR spectrometer magnet at full current (8937 Amperes).
