PALM-3000Current Status Summary
2
• Telescope simulator assembled
• HOWFS assembled and tested
• Alignment plan (CIN 636) is halfway finished
• Alignment feedback GUI developed and tested
PALM-3000Telescope Simulator
3
• On-axis green laser
• Red laser fiber source
• On x-y-z translation stage
• F/# ~15.7 (needs to be confirmed)
PALM-3000HOWFS Mechanical
4
Pieces needed for WFS fabricated and assembled.
Alignment feedback GUI developed and tested.
PALM-3000Analysis/Discussion
• Pupil ellipticity at 2.0% (1.70% desired for AOI of 10.5)– There are degrees of freedom to change the ellipticity
• Pupil size at 9.645 mm (9.600 target)• We need to establish exact pupil sizes in the
different modes before specifying collimator• Different focus measurement in different modes
– Many possible contributors, will require investigation
• CCD50 focus positions not yet established– Will require use of Pixelink camera

PALM-3000Flexure analysis
• Flexure – ATS150 roll compliance is excellent. Still awaiting pitch compliance. Expect 0.1”/hour. Khanh’s description of flexure analysis however is confusing. What priority should we place on having him document this properly?

PALM-3000Outstanding tasks - summary
• CCD50 readout modes – awaiting SciMeasure.• Test the camera modes – RN/DC (JR, ? days)• Finish alignment plan - (CB, 1 day)• Further alignment investigation – (CB, 1 day)• Amendments to alignment procedure – (CB, 1 day)• Internal flexure testing – (CB, 1 day)• Spec new optics – (CB, ½ day)• Alignment with the testbed – (CB, 2 days)• Plan for testing and incorporating new optics – (CB, 1
day)• Mechanical…

Khahn expects to be finished working on the HOWFS/Acam by end of next week.
PALM-3000Schedule
• Mechanical finished – next few weeks
• SciMeasure modes - ?
• Integration with testbed (no DM) – 3-4 weeks
• Order testbed collimator/cylinder – after F/# established
• Integration with DM in testbed – 6-10 weeks
• Integration on PALM-AO bench – next year
