• Slits 4 = DG2 Jaws
• Cut the beam down after the refocusing lenses or clean the beam after the 1 micron KB mirrors

Controls and Operations : 

DG2 Slit Motors:

CXI:DG1:MMS:01, CXI:DG2:MMS:02, CXI:DG2:MMS:03, CXI:DG2:MMS:04 all use External Encoders as encoder feedback. They are only compatible with EE motor drives (not EQ) which at the moment are MDRIVE 17 EE drive. EE motors use an external encoder and expect an external encoder resolution which should be in parameter manager.

X-ray Focusing Lenses

• Change the divergence of the 1 micron KB beam and control the spot size in SC1
• PACK2
  • Smaller focus for running experiment (X-ray probe)
  • 20-30 um at IP
• PACK3
  • Bigger focus for IP or TT timing (X-ray pump)
  • 200-300 um
• OUT position: Y = -8 mm
