TALK outline

• EMSY what, where and when
• EMSY layout
• PITZ and EMSY
• Commissioning of the device
• Whats next
• Conclusions

Emittance Measurement SYstemEMSY

• Based upon slit technique (pepper pot)
• Tungsten slit, width of 10 mm
• OTR and YAG screens installed
• Newport motors and motion controller
• YAG screen used for beamlet observation
• remote zoom optics tested

4
PITZ and EMSY

• Three new EMSYs are produced by HITECH HEP Group
  in INRNE Sofia
• Construction and successful vacuum and mechanical
  test done end of May
• June installed in the tunnel in positions 4.3,
  6.6 and 9.8 m
• Only the first system aligned
• All installed components are working properly

Whats next

• Emittance measurements
• Multi slit masks are produced

Summary

• All the installed components are working fine
• Remote zoom lenses have too low light
  transmission
• Good charge transmission from the 10 mm slit
• System is ready for use
• Thanks for your attention
