1           Project Scientist’s Report

 

There is no progress to report on NIFS science.

 

 

2            Project Manager’s Report

 

Although the NIFS contract has not been fully executed at this point in time, RSAA submits this monthly report on NIFS activities, covering the period from 4 to 29 September 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. RSAA and Gemini are exploring how the purchase of long leadtime and/or expensive items can be organised without RSAA assuming the financial risk associated.

 

Progress on CC and IS software development, control system design and procurement, and cryostat and OIWFS duplication is being hampered by the non-availability of NIRI as-built documentation.

 

2.1         Staffing

The search for competent design and workshop staff continues. Leigh Pfitzner, a designer from Auspace Ltd. Continues to work at RSAA. to overcome the skills shortage. Other avenues to fill these positions are being explored.

 

The three temporary (18 months) machinist positions in the workshop to fabricate parts for the NIRI duplication and later for the spectrograph have all been filled.

 

The advertisement for an electronics technical officer has brought a disappointing response. An employment agency has been engaged to find other suitable candidates. This is a continuing position vacated earlier in the year, which needs to be filled together with a temporary position to allow the fabrication of the NIFS control system.

 

2.2         Progress

Our review of the optical design of the spectrograph was completed. However, the sheet metal material procured for the fabrication of the field slicer is thinner than specified. Unless material of the correct thickness can be obtained, the optical design will have to be re-optimised for the smaller slicer size.

 

The assembly design of the grating mechanism took longer than expected and is now nearing completion. The first pass design of all other spectrograph assemblies has been progressed further and design of the system from pick-up mirror to slicer has been started.

 

The mechanical workshop has continued to fabricate components for the NIRI duplication. Modifications have been made to the design of the OIWFS optable to accommodate the changes necessary for NIFS and to the design of the cryocooler interfaces, as suggested by Jeff Douglass to improve cooling performance and reduce vibration.

 

The NIRI control system drawings obtained from IfA were used to compile a parts list for procurement and quotes have been obtained for the majority of components.

 

A recent version of the NIRI Components Controller software has been installed and is being modified to reflect the different NIFS mechanisms. The Detector controller IOC has been assembled and the detector controller software design has seen some progress.

 

The design of the detector mounting board has been started and the stability of the SDSU controller is being assessed.

 

2.3         Schedule

With the RSC detector contract having been executed on 12 October, science detector delivery is assumed to take place 558 days after this date, or on 23 April 2002. Our plan includes three months characterization at UH, time for transport to RSAA and another six weeks verification before integration in NIFS at the start of the fifth cooldown cycle. This pushes the date for transportation of NIFS to Hawaii out to end of December 2002.

 

It has been agreed to delay the CDR to 22 February 2001. The NIFS delivery date is being driven by the science detector delivery.

4           Schedule Progress

 

4.1         Updated Schedule

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

17 people have contributed to the NIFS project during this period. They worked a total of 1276 hours, bringing the total for the project to 3959 hrs, which represents approximately 13.0% 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 some as-built information on NIRI and its control software.

 

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. Ordering of the OIWFS optable machining, the OIWFS lenses, the SDSU controllers and parts for the control system are on hold. Possible measures to circumvent this problem are being explored.
