      Aims. We describe the design, construction, and characterization of the Band 9 heterodyne receivers (600-720 GHz) for the Atacama Large Millimeter/submillimeter Array (ALMA). First-light Band 9 data, obtained during ALMA ...
    • Zorzi Avendaño, Pablo Ignacio; Granet, Christophe; Colleoni, Franco; Reyes, Nicolás; Pizarro Lucero, José; Mena Mena, Fausto Patricio; Bronfman Aguiló, Leonardo (Springer, 2012)
      A corrugated spline-profile horn has been designed to meet the stringent specifications and constraints of a receiver for Band 1 (31.3–45 GHz) of the Atacama Large Millimeter Array (ALMA). Given the physical restrictions ...
    • Griffin, James M.; Díaz, Fernanda; Geerling, Edgar; Clasing, Matías; Ponce, Vicente; Taylor, Chris; Turner, Sam; Michael, Ernest; Mena Mena, Fausto Patricio; Bronfman Aguiló, Leonardo (Academic Press-Elsevier, 2017)
      By using acoustic emission (AE) it is possible to control deviations and surface quality during micro milling operations. The method of micro milling is used to manufacture a submillimetre waveguide where micro machining ...
    • Molina Moreno, Rocío Gabriela (Universidad de Chile, 2017)
      The new generation of telescopes that will be installed in the world and particularly in Chile is focused on the search of high-impact scientific objectives. For this, the technology used must be cutting edge, in order to ...
    • Reyes Guzmán, Nicolás Andrés; Zorzi Avendaño, Pablo Ignacio; Pizarro Lucero, José; Finger Camus, Ricardo; Mena Mena, Fausto Patricio; Bronfman Aguiló, Leonardo (SPRINGER, 2012-12)
      In this work we present a Q-band waveguide orthomode transducer (OMT) based on a dual ridge structure. It was designed to be used in astronomical projects were an excellent broad-band performance is mandatory. Of particular ...
    • Thomas, Tina; Ramaclus, Jerald; Mena Mena, Fausto Patricio; Mosquera Vargas, Edgar; Sagayaraj, P.; Michael, Ernest (Royal Society of Chemistry, 2015)
      A simple method to control the nucleation and morphology of IJ4-N,N-dimethylamino-4-N-methylstilbazoliumtosylate) DAST crystals is explored. At equal concentrations of oleic acid and DAST in methanol, pure DAST crystals ...
    • Khudchenko, Andrey; Hesper, Ronald; Baryshev, Andrey M.; Barkhof, Jan; Mena Mena, Fausto Patricio (IEEE, 2017)
      A modular sideband-separating (2SB) receiver for 600-720 GHz has been built and tested. The used modular design allows to characterize all the parts separately, including testing of the superconductor-insulator-superconductor ...
    • Carrasco Ávila, Javier Alejandro (Universidad de Chile, 2022)
      Amplification is required to detect small microwave signals. One new promising technology to achieve large amplification with quantum-limited noise is the kinetic inductance traveling-wave parametric amplifier (KI-TWPA). ...
