ARC node at IRAM F Gueth IRAM Grenoble

ARC node at IRAM F. Gueth – IRAM Grenoble 06/10/2006 IRAM Interferometry School 1

ALMA @ IRAM • IRAM deeply involved in ALMA construction • Hardware: – band 7 (280— 360 GHz) development and (pre-)production – receiver common optics – backend samplers • Software & proto-ARC: – scientific software requirements (SSR) group – real-time telescope calibration pipeline – tests of prototype antennas 06/10/2006 IRAM Interferometry School 2

Band 7, Lazareff et al. IRAM 06/10/2006 IRAM Interferometry School 3

Band 7 noise temperature, 8 GHz IF 06/10/2006 IRAM Interferometry School (Maier et al. IRAM) 4

ARC node at IRAM • IRAM partners • CNRS (France) • MPG (Germany) • IGN (Spain) • ARC node at IRAM also supported by • French community • Spain ALMA committee • IRAM open to all astronomers: 30% observing time outside partner countries, TNA Radio. Net FP 6 06/10/2006 IRAM Interferometry School 5

IRAM millimeter interferometry center • IRAM ARC node will be an activity of the IRAM millimeter interferometry center • Center is already in place – GILDAS software (CLASS, CLIC, …) – Pd. BI f 2 f user support since >10 years – mm-interferometry school series since 1998 – general expertise in mm-interferometry calibration and imaging techniques 06/10/2006 IRAM Interferometry School 6

ARC node at IRAM • Goals of mm-interferometry expertise center: § User formation § User face-to-face support § Technical expertise center § Data reduction software • Based on and fully open to collaborations with other groups • Several actions already started or planned 06/10/2006 IRAM Interferometry School 7

User formation • Interferometry school series 5 th school Oct. 2 -6 2006, 66 participants • Long-period visits of Ph. D/postdocs – Formation to mm-interferometry techniques and data reduction, observations at Pd. BI (new access) – Can start in 2007 (new building available) – Please contact us if interested 06/10/2006 IRAM Interferometry School 8

IRAM mm-interferometry school series • Every two years since 1998 • General introduction to mminterferometry, Pd. BI data reduction, introduction to ALMA • ALMA practical session in 2008 ( Early Science) • Lectures and book available on the web 06/10/2006 IRAM Interferometry School 9

User f 2 f support • In place at IRAM for Pd. BI since ~10 years – Each project has a local contact to help during the data reduction at Grenoble • Will be extended to support ALMA users – Critical for early-science required in 2009 06/10/2006 IRAM Interferometry School 10

Technical Expertise • ALMA commissioning – GILDAS to be used for antenna SD holographies • New observing mode: OTF interferometry development at Pd. BI then ALMA (EU-FP 6) • Using Jupiter satellites as mm flux calibrators: Pd. BI/30 m project started (collab. with Paris Obs. ) • ALMA imaging simulator 06/10/2006 IRAM Interferometry School 11

Software devl’t • Software developments for ALMA: – telescope calibration pipeline – GILDAS/CLIC adapted for ALMA holographies – goal: long-term support/upgrade of ALMA software • py. GILDAS development: interoperability of the data reduction software (collab. with Bordeaux Obs. ) 06/10/2006 IRAM Interferometry School 12
