NIRSPEC Cryomechanics Design Note 16.00

CCR head mounts

Introduction

The CCR head (or heads) will provide much of the cooling capacity for the instrument. As with Gemini we have to make sure the CCR head(s) is(are) vibration isolated from the rest of the dewar.

What next?

The Gemini scheme for vibration isolation seems to work well, so our design will probably be very similar to what we used on that instrument. Mostly we have to draw it and have it made.
