The linear polarization of bremsstrahlung from thin targets ({~} 50 μg/cm²) of Al, Cu, Ag, and Au was measured for incident electron energies of 50, 75, and 100 keV. The polarization was measured as a function of photon energy at four emission angles (θ=22.5^∘,45^∘,90^∘, and 135^∘). Data presented were obtained with a Compton polarimeter having a large asymmetry ratio (from 35 to 150) and high resolution. The results have been found to be in general agreement with the predictions of various bremsstrahlung calculations.
