Beam Conditioning

Slits, filters, masks and apertures that define the beam and manage its power, from undulator beamlines to superconducting wigglers.

At a glance

  • Angled water-cooled copper blades (OFHC or Glidcop) with a tungsten hard edge defining the beam.
  • One motor sets the slit gap and a second scans the slits in the beam.
  • Actuator resolution to 0.1µm, with 5µm repeatability in open loop and <1µm with an encoder.
  • Thermally isolated design for thermal stability and minimal drift.
  • Canted undulator slits with a bypass aperture for the adjacent canted beam.
  • Very high heat load slits absorbing >10kW per blade.
  • Graphite filters up to 500µm thick, absorbing >6kW.
  • Slit blade design optimised for the power requirements of the beamline.
Fixed mask and differential pump assembly with labelled vertical and horizontal primary slits, cooled aperture, bellows and ion pumps
Fixed mask and differential pump: a windowless interface to the front end.
