1           Project Scientist’s Report

 

The availability of guide stars has been further explored by developing a Perl program for downloading and displaying DSS2-R, 2MASS-K, WFPC2, and NICMOS images for a list of targets. The images are displayed with overlays for USNO stars and the NIFS guide star regions.

 

This program has been used to identify 30 Seyfert galaxies with extended (<0.3") radio jets and guide stars suitable for the ALTAIR natural guide star system.

 

A similar number of nearby massive black hole candidate galaxies are known to exist. These are predominantly S0 galaxies.

 

Further object lists will be generated and signal-to-noise ratio issues will be revisited when real observing samples are in-hand.

 

 

2            Project Manager’s Report

 

Although the NIFS contract has not yet been fully executed, RSAA submits this monthly report on NIFS activities, covering the period from 2 to 27 October 2000.

 

The period of uncertainty waiting for NSF approval of the NIFS contract still continues. RSAA continued design and fabrication work, but has not placed any further orders for equipment and materials. This may cause delays in the purchase and delivery of long leadtime items, eventually impacting on project completion. It is also holding up negotiations on a contract for cooperation with UH. IGPO has organised a side contract for NIFS, advancing US$100k on the NIFS contract with no further obligation on ANU. ANU lawyers are currently reviewing this side contract. Procurement will resume on receipt of payment for this side contract.

 

The continuing non-availability of NIRI as-built documentation hampers progress on CC and IS software development, control system design and procurement, and cryostat and OIWFS duplication.

 

2.1         Staffing

There have been no further developments in the search for competent mechanical design and workshop staff.

 

The electronics technical officer vacancy has eventually been filled by internal transfer. This leaves another vacancy to be filled at a lower level. We are exploring the possibilities to fill the temporary position to allow the fabrication of the NIFS control system.

 

2.2         Progress

Our review of the optical design of the spectrograph needed some minor adjustments. Suitable sheet metal material for the fabrication of the field slicer has been procured.

 

The assembly design of the grating mechanism has been completed. The flip mirror assembly has been started. Design of the system from pick-up mirror to slicer has been progressed.

 

The mechanical workshop has continued to fabricate components for the NIRI duplication. The design modifications for the fixed OIWFS detector mount are in progress. The OIWFS optable machining can be ordered as soon as funds become available.

 

Further quotes are being sought for the control system hardware.

 

A recent version of the NIRI Components Controller software has been modified to reflect the different NIFS mechanisms. The details at the hardware interaction level need a better understanding. The detector controller software design has seen more progress.

 

The design of the detector mounting board has progressed. The Lakeshore detector temperature controller has arrived and a liquid nitrogen dewar has been fitted with some parts to assess temperature control performance under various circumstances.

 

2.3         Schedule

No further effort has been expended on revising the schedule. It is intended to revise the schedule when NIFS funds are available again.

4           Schedule Progress

 

4.1         Updated Schedule

The schedule has not been updated this period. The current schedule is the schedule included in the “NIFS Revised Costing”. A schedule revised for the expected delivery dates of the detectors and the late start on cryostat and OIWFS duplication has been developed. It also takes into account the proposed delayed CDR. This revised schedule was submitted during September. Further changes will have to be made for the actual detector delivery dates and the effects of delayed orders for long leadtime items resulting from the NIFS contract uncertainty.

 

4.2         Project Statistics

19 people have contributed to the NIFS project during this period. They worked a total of 1082 hours, bringing the total for the project to 5041 hrs, which represents approximately 16.6% of the total number of hours in the current project plan.

6           Problem Areas

 

6.1         Technical Problems

The only technical problem impeding project progress is the unavailability of as-built information on NIRI and its control software and examples of manuals and plans.

 

6.2         Scheduling Problems

The purchase and delivery of items on the critical path of the project may be delayed because of RSAA hesitation to commit to large external purchases without the backing of a contract.

 

6.3         Financial Problems

RSAA will continue to provide labour for the NIFS project, but will make no further large external commitments until a payment has been received from IGPO. Ordering of the OIWFS optable machining, the OIWFS lenses, the SDSU controllers and parts for the control system are on hold.
