9


Systems Engineering

• Flexure Analysis:• Completed 10/00

• Results show no need for active compensation• Passive compensation via collimator mount required

• Analysis will be used to guide mount design (later this year)

• All further analysis is in support of detailed design

10


Flexure Analysis

• NASTRAN Model• Design presented 8/00

• Mechanisms, optics modeled as rigid bodies (reasonable assumption)

• Tilts and displacements calculated for 3 orthogonal gravity vectors

• Some subsequent modifications• Stiffened high-flexure areas identified by model

• Verified all mechanism interfaces

• Changes in flexure should be modest; expected but not required to improve

11


Instrument Assembly F.E.A. ModelDeformed shape scaled by 7500x loading; gravity in the –y direction; scale in inches.

10m

Note: Much of the Offner deflection is due to rigid body motion of the assembly with respect to its support bulkhead, and will not contribute image decenter.

Instrument Assembly F.E.A. ModelDeformed shape scaled by 7500x loading; gravity in the –x direction; scale in inches.

14m

13


Instrument Assembly F.E.A. ModelDeformed shape scaled by 7500x loading; gravity in the –z direction; scale in inches.

5m

14


Flexure Analysis

• Optical Model• Calculations done independently with 2 programs by E. Pearson and M.

Liang: good agreement

• Optics laid out in absolute coordinates

• Tested with rigid-body rotation of spectrograph (should have no net effect)

• Apply NASTRAN tilts/displacements to optical elements

15


Optical Ray Trace

Red ray: Spectrograph

Blue ray: On-Instrument Wave Front Sensor

16


Flexure Analysis

• Results - WFS to Slit• Differential flexure of WFS relative to slit should keep star centered on

slit to <10 m during 1 hour• Calculated shifts in microns for 1 gravity:

• Worst case for 1 hour ~5 m shift• Meets specification comfortably

Gravity x y -y -14.4 -9.0 x -1.7 -5.3 z -10.7 -0.4

17


Flexure Analysis

• Results - Slit to Detector to Slit• Differential motion between slit/star and detector should keep image

centered to 2.7 m (0.1 pixel) during 1 hour• Motion of slit image in dispersion direction (z)

• Motion of star image along slit (y) (motion of slit image similar)

• Calculated shifts in microns for 1 gravity:

Gravity z y -y -13.1 -14.6 x 1.3 3.5 z -24.2 3.5

18


Flexure Analysis

• Results - Slit to Detector to Slit (2)• Worst case 1 hour in z = 7.2 m; worst case in y = 4.0 m

• Design collimator mount to provide passive compensation for 2 largest components

• Worst case in y now 1.8 m in 1 hour (meets spec)

• Worst case in z now 3.7 m in 1 hour (factor of 1.4)

• Analyze final bench design to guide collimator mount design

• Slit/Decker

• Filter wheel assembly

• Mechanism common components• Motor drive assembly

• Cryo heads/lines• Will be ordered in March 2001

22


Electronics Status• Design activities

• Component controller thermal enclosure design completed• Hard-stop circuit required for the mechanisms and the Phytron drivers

has been designed and the schematics finished• A scale model GNIRS for harnessing design has been completed• Dewar, mechanisms and OIWFS cabling

• These cabling issues are being addressed thru the scale model GNIRS • cable routing and possible intermediary connectors• how to route cables around the Bench and thru the Radiation Shields

• A complete GNIRS thermal enclosure parts list has been prepared

• Fabrication in progress• Thermal enclosure wiring and assembly• Dewar and shield interface PCB’s• Connectors and boards on order

23


Software Status

• Component Controller code 56% complete

• High level (EPICS) code 7% complete• Waiting for completion of the electronics

thermal enclosure• The next phase is actual testing of component

controller code• Motor drive and mechanism status/position

sensing

24


Optics Status• Lenses and Windows

• Large lenses & windows in fabrication with RMI; 11 of 18 accepted• Only BaF2 lenses for short red and blue cameras remain

• Two lots of BaF2 material have failed so far; a third lot is in process

• Pupil viewer lenses ordered and received

• Mirrors• Flat mirrors to be ordered as individual mechanism design proceeds; 2

aluminum substrates & 7 glass substrates

• Gratings• Master rulings complete and tested• Grating replicas to be ordered by 12/15/00

• Filters• 7 filters ordered through UH consortium; 2 failed spec and vendor is

expected to replace

• Prisms• Prisms to be ordered by 12/15/00

25


Phytron Motor Status

• Motor qualification initiated• Tested 4 motors, 3 out of 4 failed

• Phytron is replacing all 12 motors• Delivery of first 4 replacements expected 11/15/00

• Qualification will proceed after delivery

• 2 Gemini spare motors available on loan; these will support mechanism cold testing until motors pass muster

26


Problems and Concerns• OIWFS component late delivery

• Will cause resources to be diverted from other activities to work on OIWFS integration and test

• Filter wheel will arrive untested

• Focus assembly now in NIRI has been promised to us for January 2001

• Completing bench fabrication without major rework • Contingency time to re-fabricate a bench component is marginal

• Camera drive assembly flexure testing still pending• Design modifications may affect turret drive designs on three mechanisms

• Completion of the RMI camera optics order• BaF2 material lot failures have caused a significant delay in completing the order

• Over 130 days required to grow a new lot

• We are working to assist RMI in procuring material

• Firm quotes and schedules on prisms still pending

Capital and Labor Comments

• The capital reported is as of 11/3/00• Some capital expenditures have been charged to

procurement instead of the respective WBS number

• The labor histogram shows the result of shared resources, utilizing fewer instrument makers and subcontracting work vs. doing it in-house

• Capital expenditures are expected to increase substantially in the next two quarters
