“…Especially, Rockwell 2.5 µm HgCdTe HAWAII-2 detector arrays are widely used and the HAWAII-2 array control systems have been developed also in Japan for several Subaru instruments such as MOIRCS 6 and FMOS. 7 On the other hand, Raytheon 2.5 µm HgCdTe "VIRGO" detector array is becoming popular in the astronomical community (see e.g., VISTA program 8 ). In Japan there are growing needs for the array control system for the VIRGO array.…”

We are developing a 2K × 2K format array control system (UTIRAC: University of Tokyo InfraRed Array Control system) for "WINERED", which is a new high-resolution (R max = 100, 000) near-infrared (0.9-1.35 µm) spectrograph being built at the Institute of Astronomy, University of Tokyo. UTIRAC has the following two characteristics: (1) applicable to various infrared array (with Amp-ADC integrated boards which enables easy increase/decrease of the number of input channels) and (2) based on the MESSIA5 system (for clock generation and frame acquisition) developed by National Astronomical Observatory of Japan. The goals of UTIRAC are low readout noise (< 10 e − ) and readout speed of 200 kHz/pix (for the Raytheon VIRGO array). Working tests of each board and integration test with MESSIA5 system have been completed. As a next step, we are going to test VIRGO MUX for operation 4 with outputs and to evaluate readout noise. In the near future, we will increase the number of input channels on a single Amp-AD board from one to four for the operation of arrays with 16 outputs.

A consortium of Japanese, Australian and UK groups has developed a fibre-fed near IR (J & H band) multi-object spectrographic facility (FMOS) for the Subaru telescope. In this second-generation instrument, a novel prime focus 400-fibre multi-object positioning system, ECHIDNA, is optically linked via twin cables to dual IR spectrographs. The spectrographs are located some distance away, on a dedicated platform two levels above Nasmyth. The Centre for Advanced Instrumentation at Durham University oversaw the design and construction of the optical fibre system linking ECHIDNA to the spectrographs. A modularised connector within the cable scheme and an integral back illumination unit additionally featured as part of the Durham work-package. At the time of writing (mid 2008) FMOS, including the fibre system, is installed and functional on-telescope, with commissioning currently underway. This paper provides an overview of the design and construction of the optical fibre system.

Current status of science operation at Subaru

Subaru Telescope has been in operation for open use for six years. As the first-generation instruments became all operational and as minimal engineering time has been spent for the commissioning of the second-generation instrument, science time counts over 80% of the total telescope time since 2002. Downtime is almost minimized thanks to the stability of the telescope and the instruments and to the dedication of the support staff. Due to overwhelming deficiency in national budget of Japan, Subaru Telescope faces more serious budget cut than expected. This paper presents how the observatory is/will be dealing with the reduced budget with minimum impact to the operation that may pose observers any restriction to use the telescope.
