Performance of the Two Aerogel Cherenkov Detectors of the JLab Hall A Hadron Spectrometer
S. Marrone, B. B. Wojtsekhowski, A. Acha +18
We report on the design and commissioning of two silica aerogel Cherenkov detectors with different refractive indices. In particular, extraordinary performance in terms of the numb…
An Electromagnetic Calorimeter for the JLab Real Compton Scattering Experiment
D. J. Hamilton, A. Shahinyan, B. Wojtsekhowski +26
A lead-glass hodoscope calorimeter that was constructed for use in the Jefferson Lab Real Compton Scattering experiment is described. The detector provides a measurement of the coo…
Accurate measurement of the electron beam polarization in JLab Hall A using Compton polarimetry
S. Escoffier, P. Y. Bertin, M. Brossard +10
A major advance in accurate electron beam polarization measurement has been achieved at Jlab Hall A with a Compton polarimeter based on a Fabry-Perot cavity photon beam amplifier.…
