Arcetri
NAHUAL Workshop

nahual logo

The Arcetri Observatory Infrared group will organize a technical workshop on the Cryogenics and Mechanics of Nahual. The workshop will be held at the Arcetri Observatory location from November 26th to 28th 2008.

NAHUAL is an infrared high-resolution echelle spectrograph for the Gran Telescopio CANARIAS (GTC) of the Observatorio del Roque de los Muchachos in the island of La Palma. The main scientific objective of the instrument is to measure the radial velocity (RV) with very high precision (goal of 1 m/s) in the near infrared. This difficult target stresses available technologies to their limits. The aim of this workshop is to specify the best development path to this ambitious achievement.
