Beam size and photon flux. (a) Total photon flux as a function of energy at the sample position for fully focused beam; (b) time course of beam profile during the vertical defocusing procedure from 24 µm to 70 µm over a period of 180 s; (c) beam profile of the fully focused beam 30 µm (H) × 24 µm (V) at the sample position, determined with the built-in scintillator of MD2; (d) defocused beam of 150 µm (H) × 70 µm (V) size; (e) MD2 penta-aperture with aperture sizes indicated. |
