This period, all effort has been concentrated
on coordinating the production of the Critical Design Review documentation.
This monthly report on
NIFS activities covers the four-week period from 2 February to 2 March 2001.
A NIFS contract
variation was executed to cover the extra work involved in preparing our own
NIFS control system design, using the NIRI design as a guide, rather then
trying to copy NIRI design with some changes.
The search for
competent mechanical design staff continues. The leads referred to in the
January report have unfortunately drawn blanks. We hope to readvertise next
month.
An electronics
technical officer vacancy still exists. An ex-member of RSAA staff will fill
the temporary position required for the fabrication of the NIFS control system
on a casual basis.
Both electronic and
mechanical recent vacancies have attracted the attention of staff members of
non-Australian astronomical organizations. The low exchange rate of the
Australian dollar, combined with the rather unattractive ANU salary scales, has
resulted in our inability to convert the shown interest into appointments. On a
national scale, we are disadvantaged by the reluctance of high-tech personnel
to move from Sydney or Melbourne to Canberra.
Various aspects of the
optical design continue to be checked: ghosting, scattered light, distortion,
and error budgets. The integration of the various spectrograph assembly designs
in the overall mechanical design is continuing. All this is carried out as part
of the write-up effort for the CDR documentation.
The mechanical
workshop continues to fabricate components for the NIRI duplication. The work
allocation for the parts fabrication phase has been exhausted, and the
situation has been reviewed. The communication failure which led to the late
discovery of the situation has been identified and steps have been taken to
avoid recurrence. The delay in CDR will allow us to make up the estimated 1500
hrs overspend without impacting on the spectrograph fabrication. Realized
savings on fixed costs will partially cover the cost of the labour overrun, the
remainder is expected to be covered by savings on further NIRI duplication
work, or the contingency amount associated with this phase of the work.
The problem with poor
alignment of the mounting pads of the integration frame will be rectified by,
and at the expense of, the subcontractor.
Work is continuing on
developing our own schematics and PCB layouts for most of the control system.
Most software effort
has been devoted to producing CDR documentation. A teleconference with Gemini
software developers has left us confused about what capabilities are expected
of the NIFS Detector Control software. A speedy resolution of the issues raised
is required.
The design of the
revised detector mounting board has been completed. A mock-up of the detector
housing was constructed to check the practicability of assembly.
The schedule will
undergo thorough revision in preparation for CDR.
All spectrograph
design tasks have been closed at the end of the previous reporting period.

Draft Spares List |
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 was developed. It also takes into account the proposed
delayed CDR date of 22 February 2001. This revised schedule was submitted
during September 2000. The schedule will be revised again and the new schedule
will be presented in the CDR documentation.
17 people have
contributed to the NIFS project during this period. They worked a total of 1637
hours, bringing the total for the project to 10,506 hrs, which represents
approximately 34.6% of the total number of hours in the current project plan.
89.4% of the number of hours allocated for the critical design study have been
used and 118% of those for the mechanical fabrication and supervision of the
Cryostat and OIWFS Duplication.
Listed below are the milestones defined in the NIFS contract. Milestone
3, AURA approval of Final OCDD and FPRD has been postponed to the CDR date,
which is now set for 19-20 April 2001.

The exchange rate used
is the rate applicable to a particular transaction, or the rate on the last day
of the reporting period. On 2 February 2001 the rate was 0.526.
No income was gained
during the reporting period.
The NIFS account was
charged for 1556 hrs of work for the reporting period. This is the total number
of hours (1637) minus the hours for the Project Scientist (81). The total
charge is US$54,460 (A$103,536)

Project progress is
impeded by the unavailability of as-built information on NIRI and its control
software. Measures are in place to minimise delays.
RSAA is awaiting
clarification of the functionality expected of the NIFS software, after
dicussion at a telecon caused confusion on this subject.
The purchase and
delivery of items on the critical path of the project may be delayed because of
the delayed execution of the NIFS contract and other delays caused by it.
There are no financial
problems.
