7. 30 Nov 2005User Committee7 NAC hardware issues Temperature drift in dewar (0.1K/day)

8. 30 Nov 2005User Committee8 NAC hardware issues Higher read noise on spectrograph (80 e - )

9. 30 Nov 2005User Committee9 NAC hardware issues Cooler vibrations from drive electronics

10. 30 Nov 2005User Committee10 NAC software issues No scripting capability in observing command No parallel port communication to LCVR controller No communication to AO stepper motor Small disk partition (33 Gbytes) for storing data No system backup Individual frames are stored as files No dark/flat corrected real-time image No processing capability (i.e. real-time spectroheliogram, LCVR calibration, focusing, etc) Several annoying GUI bugs

11. 30 Nov 2005User Committee11 NAC future plans Spectroscopy –1-3 microns: working now –3-5 microns: order new filters, work on systematic noise issues Polarimetry –(1-3 microns): parts in house and currently testing – goal is Fall 2006 –(3-5 microns): line list identified, substrates identified – goal is 2006 test, early 2007 data, full system 2008.

12. 30 Nov 2005User Committee12 CCD Guider Goals: –Test and verify TCS upgrade –Replace old limb guiders –Allow pointing to 1.5 solar radii –Provide full-disk solar image Hardware: –One flat pickoff mirror between M1 and M2 –Beamsplitter, H-alpha filter, 2 imaging lenses, CCD camera and video, PC control computer
