what is 3dii
What is 3DII?
  • Multi-mode spectrograph

--- includes Integral field spectrograph (IFS) mode,

Fabry-Perot mode, etc.

  • Optical wavelength (360-900nm)
  • Now used at Subaru Cassegrain Focus

“The Kyoto Tridimensional Spectrograph II on Subaru and the University of Hawaii 88-inch Telescopes”, Sugai et al., 2010, PASP, 122, 103

Present members in Kyoto Univ.:

Sugai(PI), Matsubayashi, Nakajima, Yoshimura

cf. Shimono, Akita, Hattori

In the case of Cassegrain

At UH88:

June 2002

At Subaru:

August 2002

purposes of 3dii ao188
Purposes of 3DII + AO188
  • First optical instrument used with AO

at 8-10m class telescopes

~0”.1 spatial sampling of 3DII

  • Providing evaluation of AO188

in optical wavelengths

what is needed for this
What is needed for this?
  • Mechanical interface

Nasmyth Mount

Four fixed points

  • Optical interface

dichroic mirror

slide10
Optical interface (dichroic mirror: measured)

cf. Laser guide star 589nm.

AO low-order wave-front

sensor 450-1000nm.

present status
Present status
  • Mechanical interface

Nasmyth Mount

Four fixed points

  • Optical interface

dichroic mirror

test done

setting done

to be installed on 2010 Apr 29,

with Minowa-san

cass or nasmyth in future
Cass or Nasmyth in future?
  • Both desired

Nasmyth for longer wavelengths (>650nm)

Cass for shorter wavelengths (<650nm)

We would try to minimize our changes of foci.

proposed schedule
Proposed schedule

This must not damage AO188, IRCS, Hi-CIAO schedules.

This must not damage Hawaii observatory schedules, including daycrews’ ones.

proposed schedule1
Proposed schedule

2010/2011

Optical alignment between 3DII & AO188

(by using 3DII CCD & AO188 worked)

Software integration with AO188

through Gen2 (SOSS compatible)?

Test observations
