Figure 11
Measured polarization ellipses, as recorded with the in situ and in vacuo VUV polarimeter, at 20 eV for different polarization modes: linear vertical (LV) polarization with S1 = −0.99; linear horizontal (LH) polarization with S1 = +0.99; right-handed CPL (RCP) for which the measured absolute circular polarization rate S3 is 0.99. Over the whole VUV range the measured absolute values of S3 are in the 0.97–0.99 range for both helicities. |
