(a) Cryo-stream shutter for remotely controlled sample annealing with a pneumatically actuated flexor mechanism. The unit is fabricated in a rapid prototyping polyamide process based on the design by Helmholtz Zentrum Berlin (Mueller et al., 2012BB18). Left: open position, default. Right: blocking position. The cold stream is diverted to the bottom right direction in the image. (b) Beam-shaping devices, downstream of the reflective objective of the microspectrophotometer. Left: scatter guard collimator, a Mo tube with 0.5 mm outer and 0.3 mm inner diameter, to confine air scatter from the beam up to 5 mm upstream of the sample. Center: triple aperture. Right: data collection configuration with aperture and collimator in the beam.
