A knife-edge measurement of the beam profile of STXM 5.3.2.2 using a focussed ion beam milled metallic glass

► Knife edge measurement of the STXM 5.3.2.2 beam profile. ► Knife edge composed of 60% gold, 20% nickel and 20% hafnium. ► The knife edge is a metallic glass and was milled with a focussed ion beam. ► The STXM 5.3.2.2 beam profile is asymmetric and is 120-150 nm wide. ► The results are consistent with previous measurements by other techniques.
