Experimental setup for acquiring images resulting from X-ray dichroism. MP: silicon 422 monochromating polarizer. PR1 and PR2: first and second diamond 111 phase retarders. PD1: PIN photodiode monitoring X-rays reflected by the first phase retarder. PD2: PIN photodiode monitoring X-rays Bragg-reflected by the second phase retarder. IC: ionization chamber monitoring X-rays incident to the sample. S: sample. SR: synchrotron radiation. |
