Persistence characteristics of H4RG-15 detectors for ESO instruments
Elizabeth M. George, Domingo Alvarez Mendez, Nagaraja Naidu Bezawada +3
As a part of the ESO Instrumentation Program, we already ordered 23 H4RG-15 (2.5 um cut-off) detectors for the instruments MOONS, MICADO, and HARMONI, with more of these detectors…
The ESO's Extremely Large Telescope Working Groups
Paolo Padovani, Michele Cirasuolo, Remco van der Burg +82
Since 2005 ESO has been working with its community and industry to develop an extremely large optical/infrared telescope. ESO's Extremely Large Telescope, or ELT for short, is a re…
Instrumentation for ESO's Extremely Large Telescope
Suzanne Ramsay, Michele Cirasuolo, Paola Amico +21
Design and construction of the instruments for ESO's Extremely Large Telescope (ELT) began in 2015. We present here a brief overview of the status of the ELT Instrumentation Plan.…
Performance advantages of buffered mode operation of HxRG near infrared detectors
Naidu Bezawada, Derek Ives, Domingo Alvarez +4
The Teledyne HxRG detectors have versatile and programmable output options to allow operation of them in a variety of configurations such as slow unbuffered, slow buffered, fast bu…
Characterisation, performance, and operational aspects of the H4RG-15 near infrared detectors for the MOONS instrument
Derek Ives, Domingo Alvarez, Naidu Bezawada +2
MOONS is a multi-object spectrograph for the ESO VLT covering a simultaneous wavelength range of 0.6-1.8 microns using approximately 1000 fibres. It uses four Teledyne Imaging Syst…
Detector Systems Engineering for Extremely Large Instruments
Elizabeth M. George, Naidu Bezawada, Derek Ives +22
The scientific detector systems for the ESO ELT first-light instruments, HARMONI, MICADO, and METIS, together will require 27 science detectors: seventeen 2.5 m cutoff H4RG-15 d…
Pyxel: the collaborative detection simulation framework
Thibaut Prod'homme, Frédéric Lemmel, Matej Arko +5
Pyxel is a novel python tool for end-to-end detection chain simulation i.e. from detector optical effects to readout electronics effects. It is an easy-to-use framework to host and…
Simulations and Design of a Single-Photon CMOS Imaging Pixel Using Multiple Non-Destructive Signal Sampling
Konstantin D. Stefanov, Martin Prest, Mark Downing +3
A single-photon CMOS image sensor design based on pinned photodiode (PPD) with multiple charge transfers and sampling is described. In the proposed pixel architecture, the photogen…
Predictive model of persistence in H2RG detectors
Simon Tulloch, Elizabeth George
Infrared hybridized detectors are widely used in astronomy, and their performance can be degraded by image persistence. This results in remnant images that can persist in the detec…
Fast method of crosstalk characterization for HxRG detectors
Elizabeth M. George, Simon M. Tulloch, Derek J. Ives
HxRG detectors have crosstalk between amplifier channels at a scientifically relevant level. In principle, crosstalk signals can be fully calibrated and removed from data, but only…
ERIS: revitalising an adaptive optics instrument for the VLT
Richard Davies, Simone Esposito, Hans Martin Schmid +63
ERIS is an instrument that will both extend and enhance the fundamental diffraction limited imaging and spectroscopy capability for the VLT. It will replace two instruments that ar…
