Main Window:

(1) Schematic of beamline components

The main body of the entry Window depicts a schematic of the beamline from the monochromator (outside the hutch) all the way to the I1 ion chamber at end-station1 inside the hutch.

  • I1: This is the Ion chamber measuring the X-ray flux coming through the Slits

  • Slits: These are the slits set around the position of the primary focus of the X-ray beam. The X-ray beam moves in the plane of the slits (i.e. perpendicular to the beam direction), when it gets out of focus. 
    We can therefore use the flux through these slits to tune the focus. See M2 2:1 Toroid and Double Xtal Mono)

  • Fast Shutter: This is a fast shutter that allows timing of exposures downstream of this position. The icon is active; when you click on it, you can open or close the Fast Shutter. Note that on ACQ you have a direct open/close toggle to control the Fast Shutter.
  • Filter Box: This is a box containing 4 sets of X-ray filters allowing to attenuate the X-ray beam if needed. It is mostly used when doing single crystal diffraction. The icon is active; when you click on it you can change the filter settings.
  • BPM: Obsolete
  • PSS: This refers to the Personal Safety Shutter. It shows its status only and cannot be controlled here. It is controlled either with the button on the rack above your head or from the EPS system.
