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 (5^th 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)

Sample frame

• Sample holder frame sizes are 1 cm (H) x 2.5 cm (V) and 3 cm (H) x 2c cm (V)

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.

2. Stage configuration set at 45 degrees
