Micro-mode


Specifications

  • Beam focused by KB mirrors
  • Step-based or bi-directional fly imaging
  • Sample stage at either 90 or 45 degress to the incoming beam
  • Keyence camera with long working distance (85 mm), high zoom (variable) lens for sample visualization
  • Samples in ambient air or He gas box
  • Cryo Jet/LN2 Linkam for sample cooling (to be commissioned)

Beam size and flux

Beam spot sizes measured at 45 degrees (meaning ~1.41X increase in beam H size) and at 10 keV (5th harmonics):

  • 10 μm (H) x 5 μm (V) flux 3.2 x 1011 ph/s/100 mA (full focused beam limited only by the acceptance of the KB mirrors)
  • 6 μm (H) x 5 μm (V) flux 1.5 x 1011ph/s/100 mA (beam cut horizontally at the secondary source)

Setups

1. Stage configuration set at 90 degrees 

  • Micro-stage set at 90 degree orientation with two Vortex detectors (1-element and 4-element) on each side of the beam path.
