Descripción
We present a description of a new instrument development, HARPS3,
planned to be installed on an upgraded and roboticized Isaac Newton
Telescope by end-2018. HARPS3 will be a high resolution (R≃115,000)
echelle spectrograph with a wavelength range from 380-690 nm. It is
being built as part of the Terra Hunting Experiment - a future 10- year
radial velocity measurement programme to discover Earth-like exoplanets.
The instrument design is based on the successful HARPS spectrograph on
the 3.6m ESO telescope and HARPS-N on the TNG telescope. The main
changes to the design in HARPS3 will be: a customised fibre adapter at
the Cassegrain focus providing a stabilised beam feed and on-sky fibre
diameter ≍1:4 arcsec, the implementation of a new continuous ow
cryostat to keep the CCD temperature very stable, detailed
characterisation of the HARPS3 CCD to map the effective pixel positions
and thus provide an improved accuracy wavelength solution, an optimised
integrated polarimeter and the instrument integrated into a robotic
operation. The robotic operation will optimise our programme which
requires our target stars to be measured on a nightly basis. We present
an overview of the entire project, including a description of our
anticipated robotic operation.
