GRACES<br />
<strong>Gemini</strong> Science Meeting, July 16-20 2012, San Francisco, CA.
The GRACES Project<br />
• Turn <strong>ESPaDOnS</strong> in<strong>to</strong> a multi-facility <strong>Gemini</strong>-<br />
<strong>CFHT</strong> shared spectrograph<br />
• It will allow <strong>Gemini</strong>-N <strong>to</strong> offer <strong>ESPaDOnS</strong> as a<br />
facility high-resolution spectrograph<br />
• Phase 1: Experimental Phase. The goal is <strong>to</strong><br />
demonstrate the concept. Include design,<br />
fabrication, installation of parts, and on-sky tests<br />
• Current schedule aims commissioning in 2013A<br />
GRACES<br />
<strong>Gemini</strong> Science Meeting, July 16-20 2012, San Francisco, CA.
Reasons for GRACES<br />
• For <strong>CFHT</strong>: financial, recognition through citations,<br />
in-house development (e.g. OPERA), promote<br />
partnerships, and spearhead future projects.<br />
• For <strong>Gemini</strong>: quick and inexpensive solution <strong>to</strong><br />
obtain high-resolution spectroscopy capability.<br />
• Synergy between co-partner programs (Canada,<br />
Brazil, UH)<br />
• First Mauna Kea multi-facility project. A step<br />
forward for future projects like OHANA, SPIRou,<br />
ng<strong>CFHT</strong>, etc.<br />

GRACES Operational<br />
Constraints for <strong>ESPaDOnS</strong><br />
• <strong>ESPaDOnS</strong> will be available for <strong>Gemini</strong> whenever it is not being<br />
used by <strong>CFHT</strong> for either observations, maintenance, or other<br />
servicing periods.<br />
• <strong>CFHT</strong> night time usage will be scheduled in blocks of time on a<br />
semester basis, though the maintenance needs of the instrument<br />
may occur at any time.<br />

<strong>Gemini</strong> Science Meeting, July 16-20 2012, San Francisco, CA.
<strong>ESPaDOnS</strong> at <strong>CFHT</strong><br />
• Bench mounted high-resolution optical echelle spectropolarimeter<br />
• Spectral range: 370 nm <strong>to</strong> 1050 nm<br />
•<br />
3 instrument configurations at <strong>CFHT</strong>:<br />
(1) Star-only: 1 fiber, 6 slices; R=80K<br />
(2) Star+Sky: 2 fibers, 3 slices; R=65K<br />
(3) Polar: 2 fibers, 3 slices; R=65K<br />
• Current RV precision ~ 150 m/s<br />
• Limit magnitude V < 17 mag<br />
• No continuum calibration<br />

✓ <strong>Remote</strong>ly operate an instrument at <strong>CFHT</strong> from <strong>Gemini</strong>-N/Hilo is a first<br />
✓ Using data reduction S/W developed by <strong>CFHT</strong> (OPERA) for <strong>Gemini</strong> users is a first<br />
GRACES is a logical segue <strong>to</strong> an even more powerful facility...<br />
<br />
A NIR fiber feed from <strong>Gemini</strong>’s 8m aperture <strong>to</strong><br />
SPIRou, the hi-res, NIR echelle spectro-polarimeter,<br />
<strong>CFHT</strong>’s next generation planet finder, first light Jan 2016!<br />
