Call for
The far-infrared to the millimeter region of the Electromagnetic Spectrum contains a wealth of information about the Universe at early epochs. Observations of cold gas and dust uniquely probe the earliest stages in the formation of galaxies, stars, and planets, with, for example, the blackbody emission of a 10 K source (or a 40 K source at redshift ~3) peaking at around a wavelength of 300 µm. At longer millimeter wavelengths the cosmic microwave background (CMB) and the Sunyaev-Zeldovich effect provide remarkably powerful tools for probing the history of the universe and determining its large-scale structure and mass/energy content.

As exemplified by the ALMA interferometer, which is now delivering groundbreaking science and taking its place among the leading observatories in the world, astrophysics at millimeter through far-infrared wavelengths has become a mainstream endeavor. Major new initiatives include the LiteBIRD CMB polarization satellite recently selected by JAXA for launch in the 2020s as well as the ESA-led far-infrared space observatory SPICA selected as one of three candidates for the M5 mission in ESA's Cosmic Vision science programme. In addition, large projects such as CMB Stage 4 and the Origins Space Telescope are being considered by the 2020 U.S. Decadal Survey. These and numerous smaller-scale projects continue to place stringent demands for advancements in detector and instrument technologies. For imaging arrays, the pixel count continues to grow to thousands of pixels and beyond. Adaptations of the basic detector technologies to produce polarimetric focal planes and ultra-low-noise devices for the demanding space environment continue to be of primary importance. Meanwhile, heterodyne receivers continue pushing forward to better sensitivity, more functionality, larger arrays, and local oscillator technology at higher terahertz frequencies.

This conference aims to bring together astronomers, physicists, and engineers working on detectors and instruments for the far-infrared/submm/mm wavelength range. It will cover current and future imaging and spectroscopic arrays, both direct detection and heterodyne, for ground-based and space-borne telescopes, the physics of semiconducting and superconducting detectors and readouts, the optimization of long-wavelength optical systems, new developments in coherent receivers and spectrometers, and the design and optimization of components such as optics and filters. In addition to these component technologies, the conference will examine instrument architectures as well as recent application examples.

Oral and poster contributions are welcome from academic, industrial, and government laboratories in the following subject areas:
  • performance requirements: science drivers and fundamental limits;
  • instrumentation (imaging, polarimetric, and spectroscopic): design and construction
  • instrument performance: validation in the laboratory, on-sky commissioning, and scientific results;
  • detectors: device physics, design, fabrication techniques, performance, and numerical modeling;
  • receiver technologies: mixers, MMICs, local oscillators, low-noise amplifiers, arrays and packaging;
  • signal read-out: electronics, multiplexing techniques and back-end spectrometers;
  • optical design: optical physics and simulations, optical layouts, test facilities, and performance demonstration;
  • optical components: materials, filters, waveguide elements, shielding, low-temperature material properties, and numerical modeling;
  • other associated technologies: mechanical design, mechanisms, coolers, and cryogenics;
