ABOUT THE CONFERENCE
Terahertz instrumentation for astronomyIntroduction:
Astronomical discoveries are driven by technological developments since the invention of the telescope by the Dutch glassmaker Hans Lippershey and its application by Galileo Galilei to discover the 4 biggest moons of Jupiter. Even today there is no field where discoveries are applied as fast as astronomy, and the THz frequency region is the current frontier: This part of the electromagnetic spectrum is poorly explored, due to technological challenges as well as the earth’s atmosphere. It also is the wavelength range where clues can be found on many relevant questions in astronomy and planetary science. In this workshop we will link the new technological developments to new science.
The morning program is a lecture series of 3 lectures explaining all basic principles of astronomical instrumentation, including optics, antenna’s detectors and full systems. In the afternoon two keynote speakers will highlight recent developments in Europe and the USA. At the end there will be a lab tour just prior to the opening reception of the conference.
Willem Jellema received the M.Sc. degree in applied physics from the University of Groningen, Groningen, The Netherlands, in 1998, and the Ph.D. degree in applied physics from the Faculty of Mathematics and Natural Sciences, University of Groningen, in 2015, on the optical design and performance verification of Herschel-HIFI.,He is currently a Senior Instrument Scientist with the SRON Netherlands Institute for Space Research, Groningen, The Netherlands, where he has been since 1998. From 1998 to 2015, he was an Instrument Scientist involved with the Herschel-HIFI project, responsible for the end-to-end optical design verification, alignment, and calibration. Since 2009, he has been an Instrument Scientist of SPICA-Safari, a far-infrared spectrometer proposed for a large aperture cryogenic telescope in space. In 2014, he became the Lead Systems Engineer of SPEX, an optical multiangle spectropolarimeter for future atmospheric missions. In November 2017, he temporarily moved to NOVA to support the development of the METIS, MICADO, and MOSAIC instruments for the E-ELT as an (Optical) Systems Engineer. In January 2018, he returned to SRON in his role as an Instrument Scientist for SPICA-Safari. He has been involved in various other projects related to the development, engineering, and calibration of submillimeter-wave and optical instrumentation for space. His research interests include long-wave diffractive optics and coherent heterodyne technologies and applications.
Maria Alonso-delPino received her degree in Telecommunications Engineering from the Technical University of Catalonia (UPC), Barcelona, Spain in 2008; her M.S. in Electrical Engineering from the Illinois Institute of Technology, Chicago, IL, USA in 2008; and her Ph.D. degree in Signal Theory and Communications/Electrical Engineering from UPC in 2013. From 2014 to 2015 she was as a postdoctoral researcher at the Technical University of Delft (TUDelft), Delft, Netherlands. From 2015 to 2016, she was a NASA postdoctoral fellow at the Jet Propulsion Laboratory (JPL), Pasadena, CA, USA. From 20216 to 2020, she was a member of the technical staff at the Sub-millimeter Wave Advanced Technology group of JPL/NASA. Since 2020, she is an assistant professor at TUDelft. Her interests include millimeter and submillimeter-wave heterodyne and direct detection receiver technologies, antennas, quasi-optical systems. Dr. Alonso-delPino was the recipient of the Outstanding Reviewer Award of the IEEE Transactions on Terahertz Science and Technology in 2013 and the co-recipient of the 2014 IEEE Terahertz Science and Technology Best Paper Award.
Jochem J.A. Baselmans (male, born 1974, native of the Netherlands): Has a PhD degree in Physics (summa cum laude) from the University of Groningen. The subject of his thesis was to study the microscopic properties of Josephson Junctions made from Superconductors and normal metals. After his Ph.D. he was a post-doctoral researcher at SRON Groningen where he worked on the development of hot electron bolometer mixers, the most sensitive heterodyne receivers for frequencies above 1.5 THz. In 2004 he moved to SRON Utrecht and started the Dutch effort on Microwave Kinetic Inductance Detectors (MKIDs), He now leads the MKID research, which has grown to be a collaboration between SRON and TU Delft as senior instrument scientist within SRON with a part time position in the THz sensing group. He is involved in several international collaborations and instrumentation projects, in particular he is end responsible for the detector development for the aforementioned AMKID sub-mm camera. He has co-authored more than 80 scientific papers, of which 3 are Nature family papers.
Elena Saenz (S’04–M’08) was born in Viana, Navarra, Spain, in 1981. She received the M.Sc. and Ph.D. degrees from the Public University of Navarra (UPNA), Pamplona, Spain, in 2004 and 2008, respectively, both in Telecommunication Engineering. Her doctoral research was focused on the analysis and design of meta-surfaces with emphasis on their application as superstrates for planar antennas. Since 2008, she has been working at the European Space Research and Technology Centre (ESTEC), European Space Agency (ESA), Noordwijk, The Netherlands with main interest in frequency/polarization selective surfaces, (sub)millimetre wave technologies and applications, antenna measurements and material characterization. She has supported several ESA missions for Earth Observation (MetOp Second Generation), Science (SPICA, JUICE), Robotic Exploration (ExoMars) and Telecommunication (SGEO). Dr. Saenz received the Loughborough Antennas and Propagation Conference (LAPC) 2006 and 2007 Best Paper Awards and the International Workshop on Antenna Technology (IWAT) 2007 Best Paper Award. In 2008, she received the IEEE Antennas and Propagation Society Graduate Research Award. She was co-author of the best paper in measurements at EuCAP 2018.
Alain Maestrini received is PhD. degree in electrical engineering from the University of Western Brittany in 1999. Until 2019 he was an associate professor at Sorbonne University and at the Observatory of Paris. His research focused on THz electronic sources and mixers for space applications. He lead the French hardware contribution to the Submillimeter Wave Instrument (SWI) for ESA JUpier ICy moons Explorer that included the 1200GHz Schottky sub-harmonic mixer and the submillimeter wave frequency multipliers of SWI. Since 2019 he is a senior member of the Submillimeter Wave Advanced Technology team at the Jet Propulsion Laboratory, California. His current research focusses on millimeter-wave and sub-millimeter phased arrays and THz Schottky heterodyne receivers for planetary science and heliophysics.
