Quarterly ReviewOctober 5, 2001
Response to June QR
• Late delivery of the OIWFS - Contingency plan
– The contingency plan that was agreed upon was to install the OIWFS bench with mass models and continue with integration. Gemini would be responsible for integrating the OIWFS components at a later date.
– Implementing this plan was not necessary as the components did eventually arrive and can be integrated without serious schedule impact.
• 2 month schedule slip– The project is considered to be behind schedule by about 2 months. This
lag was specific to the Design and Fabrication phase of the project. Schedule re-planning has been done to minimize the impact on the integration phase. The effect is to deliver the instrument in September rather than in August.

Quarterly ReviewOctober 5, 2001
Response to June QR
• Documentation and change orders– A draft outline of the ATP and commissioning plan has been
submitted to Gemini and reviewed. ATP is being developed, at Gemini’s request, in conjunction with the commissioning and training plan.
– A change order is in process which addresses acceptance testing, training and commissioning in Chile. Jay Elias has the action to produce a plan which will be based on the outline already submitted to Gemini.
– The rotary and linear prototype test reports were not deliverables. These items were reported on at the Mid-Fab Review and by internal emails and SDN’s sufficient to proceed with the design of the affected mechanisms.
13
Quarterly ReviewOctober 5, 2001
Response to June QR
• Dewar warm-up controller– This controller is an ancillary box which is not needed until we
begin actual cold testing of the instrument. Fabrication is therefore a low priority task which has been scheduled to be done at a later date.
• Systems engineering effort– This effort has been reported as completed on all our status reports
as all tasks associated with the initial engineering effort in the baseline plan have been accomplished. There is a sustaining engineering function in which the systems engineer (Jay Elias) oversees the entire design effort and gives support as required. This will continue until the instrument is delivered to Gemini.
14
Quarterly ReviewOctober 5, 2001
Response to June QR
• Fabrication delays due to vendor performance and rework– We have experienced several delays from various vendors who are
fabricating components for the instrument, including rework on several components. This has had the most serious impact on the start of mechanism testing. We are past this period and all but one mechanism has finished mechanical fabrication.
– The Bulkhead Assembly and Dewar Shells have been delayed due to design changes to incorporate ballast weights and the cryo manifold. The delay amounts to about 1 month, but is not pacing the project as the vendor has also been contracted to do vacuum testing on the assembled Bulkhead Assembly and Dewar Shells. This task is considered part of integration testing.
15
Quarterly ReviewOctober 5, 2001
Response to June QR
• Flexure rig need date– The flexure rig need date of mid-February 2002 was impossible to
attain due to the time required to procure the rig and build a building to house it. A more realistic date for having the facility in place and operational is mid-April. We had intended to test as soon as practicable in order to identify any flexure issues. We have adjusted our schedule to accommodate the predicted availability date.
• Rolling wave (labor)– The charts in the Project Management section show that we still
have a peak in labor resource need in the month of November. The peak is down from that shown in the last QR and is dissipating. This peak should be gone by the end of December.
16
Quarterly ReviewOctober 5, 2001
Response to June QR
• Staffing in the design drafting area– At the time of the last QR design drafting was a critical path item. This is
no longer the case as the designers have accomplished the backlog of work that kept them on the critical path.
• IFU late delivery– Because of the delay, we are proceeding with mass modules. We will try
to accommodate Gemini in integrating the IFU when it becomes available.
• Status of Bulkhead Assembly– The design took longer than originally planned, and the final release to
fabrication was further delayed in order to ensure that the design was complete. Some design changes were required after the release. This is a complicated assembly with many parts. The unit is currently in fabrication and will be completed in October. It will then be leak tested with the Dewar Shells, which are also in fabrication at the same vendor. Images of these assemblies are shown in the Appendix.

Quarterly ReviewOctober 5, 2001
Response to June QR
• Software: Which version of the NIRI Code is being used?– GNIRS is not using the NIRI code. This decision was based on much
discussion and on the recommendation of Hubert himself.
• Software: Look at using OCSwish– We have finally received the OCSwish tool and are using it. So far we
see no problems in using it for integration with our EPICS code. This is discussed in more detail in the software portion of this review.

Quarterly ReviewOctober 5, 2001
FTE Projection• Table shows the resources forecast over the next fiscal year• There is a peak in the resources needed in Nov - Dec
– “Rolling wave” is spread over two months– The MS Project “wave” is an attribute of how MS Project works
when it assembles monthly data• It misrepresents the amplitude of the wave in November by the way it
handles its calendar– Hours actually spread over adjacent months can compress into one month,
showing resources overloaded one month and under utilized the next, making a peak need in resources look worse than it actually is
• We estimate approximately 21,000 hrs total needed to finish the project– This does not include commissioning or the impact of the pending
change order for delivery to Chile

Envelope Waiver
Supplemental Envelope Waiver Request
This request supplements our May 2001 envelope waiver request. It details some additional minor envelope violations due to routing of the high-pressure helium lines and other connections. The violations are indicated in the figures below, and described in more detail afterward.
This waiver request has been granted via e-mail as of September 27 by Doug Simons.
118
Quarterly ReviewOctober 5, 2001
Figure 1. Summary of GNIRS envelope violations, include those previously approved by Gemini. The Gemini instrument envelope is shown overlaid on the instrument itself.
119
Quarterly ReviewOctober 5, 2001
There are four areas where the helium lines violate the envelope:
The first location is at the bottom of the instrument, where the lines and manifold protrude approximately 66 mm outside the envelope. Although the instrument "feet" extend still further (92 mm), they can be removed if required. The footprint of the hoses is also much smaller, and we believe that it should be possible to miss them, even when the instrument is mounted up-looking and it is necessary to access the side-looking instrument located immediately above.
Hose loops from the forward cryoheads protrude outside the instrument in two locations (either side). The protrusion is about 100 mm in depth and roughly twice that in length, as indicated in the figure.
We are providing a connector panel at the instrument. All cables and hoses that run to the Gemini connector panel on the rotator would run from this instrument panel, facilitating installation of the instrument. However, the panel also protrudes outside the envelope, by a maximum of ~120 mm. The panel runs about half the height of the instrument, so there is still good access to the corners of the ISS cube, where GNIRS will be attached.
