HARMONI at ELT: Design and Tests Results of the Instrument Cryogenic Fast Shutter
21 June 2024 • 11:15 - 11:30 Japan Standard Time | Room G214, North - 2F
Abstract
HARMONI is the first light visible and near-IR integral field spectrograph for the ELT. The core of HARMONI is the Integral Field Spectrograph (IFS) which includes the Pre-Optics Fast Shutter (POFS), a mechanical cryogenic shutter which will be used with both the visible and infrared detectors. This mechanism has been designed to be fast and reliable and its design has already passed the Critical Design Review (CDR) but specific issues that require further analysis have been identified . This works presents the POFS design and the tests performed on a prototype to validate it and analyze possible improvements before the Final Design Review (FDR).

Teodora Viera, senior engineer in the Electronics Department of the IAC. Experience in design, integration and verification of electronic systems in astrophysical instrumentation since 1990.
The Solar Tracking Correlator (KIS-IAC) (1990-1993), Optical Ground Station (ESA-IAC) (1994-2003), IAC80 and Carlos Sanchez telescopes electromechanical and instrumentation upgrade (IAC)(2003- 2005), Adaptive Optics using FPGAs (IAC) (2005-2009), Extremely large telescopes associated technologies (ESO-IAC) (2005-2009), PACT-ELT Prototype (E-ELT M1 Position Actuator) (CESA-IAC) (2009-2011), QUIJOTE Scientific Development Programme (Microwave Instrumentation) (IAC) (2011-2021), HARMONI (High Angular Resolution Monolithic Optical and Near-infrared Integral field spectrograph) (ELT instrument) (2021-Now) are the main projects I have been involved in.
The main capabilities acquired are in electromechanical, automatic and control, real-time processing, digital electronic design.
