IμS with Molybdenum Radiation – Quality data from very small crystals

The IμS with Quazar optics delivers a 2D focused beam that provides a flux density of more than 1 x 109 X-rays/(s mm2). This is more than 4 times the flux density of a 2KW Mo sealed tube and about 1.5 times the flux density of a 5.4 KW rotating anode with graphite monochromator. For very small crystals, the APEX II QUAZAR shows an intensity gain of about 15x compared to a standard sealed tube system.

Research advances at an unprecedented speed and systems to be structurally investigated show higher and higher complexity. Often only very small crystalline specimens can be obtained that elude structural investigation using conventional sources. The Molybdenum IMS source with its small high intensity beam (120 μm FWHM) is ideally suited to investigate tiny samples providing maximal flux density at the crystal and minimizing scatter from air and crystal mount.
