Integrated heterodyne array receivers for submillimeter astronomy [PDF]
SPIE Proceedings, 2003 The advent of large format (~100 pixel) spectroscopic imaging cameras at submillimeter wavelengths would fundamentally change the way in which astronomy is performed in this important wavelength regime. While the possibility of such instruments has been discussed for more than two decades, only recently have advances in mixer technology, device ...

Observing Conditions for Submillimeter Astronomy [PDF]
, 2011 Consistently superb observing conditions are crucial for achieving the scientific objectives of a telescope. Submillimeter astronomy is possible only at a few exceptionally dry sites, notably Mauna Kea, the Antarctic plateau, and the Chajnantor region in the high Andes east of San Pedro de Atacama in northern Chile.

Beam-axis stability during gantry rotation measured with scintillation dosimetry. [PDF]
J Appl Clin Med PhysAbstract Purpose Volumetric modulated arc therapy (VMAT) requires high mechanical precision due to continuous gantry rotation. This study aims to investigate beam‐axis stability during VMAT delivery and evaluate scintillation‐based imaging as a complementary quality assurance (QA) tool.

Submillimeter Wave Astronomy [PDF]
1976 International Conference on Submillimeter Waves and Their Applications, 1976 Scientific Overview Astronomical observations at submillimeter wavelengths, between 40 μm and 1 mm, study astro-physical sources and problems which differ from and complement those accessible at other wavelengths. Although a few nonthermal sources are known, most of the radiation observed in this spectral band from astronomical sources outside of the ...

Outflows and disks of brown dwarfs with SMA, CARMA and ALMA
EPJ Web of Conferences, 2013 Brown dwarfs are on the dividing line between planets and stars. Up to date, about 1,000 brown dwarfs, including the coolest known brown dwarfs with temperatures of ∼300 K as cool as the human body, have been discovered.
