  2. Outline • A year in the life of HMI development • HMI assembly progress • HMI testing progress • Near term events • Schedule summary The last time we met, we had finished CDR and were starting structural model testing.

  3. HMI Assembly Status Feb Apr May Mar Structural model testing completed Received flight Michelsons All flight optics in house ETU oven testing completed BB HEB fabrication completed SUROM acceptance test completed mission CDR Jun Aug Jul Hollow core motors completed Received DM cameras Received 4 grade zero CCDs Received flight structure Start alignment on GSE bench Received flight metering tube Completed telescope alignment Nov Oct Sep Dec Alignment mechanism completed Started optical alignment of HOP Focal plane completed Oven completed First image BB HEB and EGSE ready Shutter & F/C wheels completed Internal harness completed Lyot completed Internal mechanisms tested

  4. Internal Harness (Flight, not complete) Shutters (Flight) BDS Fold Mirror (Flight) Alignment Mechanism (Flight, hidden in view) BDS Beamsplitter (Flight, hidden by shutter) Oven Assembly (non-flight) Parts to replace: E1 and E2 in Lyot NB Michelson Painted housing CCD Fold Mirror (Flight, hidden by detector) Detector Assembly (Non-Flight) Oven Controller (ETU) Flex-Cables (Eng Model) ISS Beam Splitter (Flight) CEB (Non-Flight, DM1) ISS Mirror (Flight) Limb Sensor (Non-Flight) Polarization Selector (Flight) Limb Pre-amp Box (Flight, not complete) Focus/Cal Wheels (Flight) Telescope (Flight) Structure W/ legs and heaters (Flight) Front Window (Flight) Optics Package Assembly • Primary work after Sun testing: • Bond optics in place • Replace painted parts (including the oven) • Replace one HCM and focus/cal optical mounts HMI Assembly Status

  5. “HMI is Alive” First Image “Special Target” First Lamp Image “Ready to Test” Instrument All Together “No More Moon” Better Laser Image “It’s a Beautiful Day” First Sun Image Laser dot Before holiday No relay lens No Lyot No frt Window Special target Lamp - stim tel Lyot installed Temp mnt for relay lens Not fully aligned stim tel Air Force target Lamp - stim tel All together Laser intensity improved Just sunlight With air/vac corrector 12/22/06 01/11/06 01/25/06 02/01/06 01/30/06 HMI Testing Progress Tests Performed: Initial set up w/ lamp Focus test w/ lamp Distortion, field curvature and MTF w/ lamp Focus test w/ Sun Filter wavelength dependence w/ Sun Tests In Progress: Filter wavelength dependence w/ laser Field curvature and MTF w/ Sun Polarization calibration w/ Sun

  6. HMI Testing Progress First Dopplergram First Magnetogram

  7. Upcoming Events • Near term key hardware items • Continue Sun testing • Continue ISS testing • Complete rebuild of oven • Replace Lyot E1 and E2 • Replace narrow band Michelson • Replace one wave plate mount and focus block mounts • Bond optics in mounts • Install flight focal planes and align CCDs • Further out • In air calibration Mid April – May • Vacuum calibration June – mid July
