3 Introduction

The Gemini Near-infrared Integral Spectrograph (NIFS) is expected to have a 10 year nominal lifetime. Only the cryocoolers are expected to need refurbishment or replacement during this period. Other spare parts are recommended to cover random breakdowns, mainly of electronics equipment. These items are listed below.

Some electronic circuit boards are being developed by ANU. It would be cost effective to fabricate spares for these boards during the development phase. To this end, Gemini should give an early indication of which spares are to be procured.

Notes:

These spares are suitable for both science and OIWFS detector controllers.
These boards contain areas which have to be populated differently for the science and OIWFS detectors. If spares are required for immediate board swapping, versions for HAWAII-1 and HAWAII-2 detectors should both be procured. Otherwise single boards will suffice, to be modified if needed.
