PALM-3000 Analysis/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 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 10

PALM-3000 Flexure 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? 11

PALM-3000 Outstanding 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… 12
