NOVA* Submm Heterodyne Array Workshop

9 – 11 March 2017,

Nunspeet, the Netherlands


NOVA, the Nederlandse Onderzoekschool Voor Astronomie, is organizing a workshop on submm heterodyne arrays, in March 2017, just before the ISSTT-2 in Cologne.

The rationale for the workshop is that observing facilities like a 10+m class FIR space observatory, enhancements of existing telescopes like ALMA and IRAM, require large arrays with at least ten times more pixels, implying one has to aim for an order of magnitude reduced power consumption per pixel and an efficient LO injection scheme.  A high degree of integration is essential. Digitization and digital pre-processing early-on in the signal path are very desirable. Furthermore, one needs to address the power -and mass hungry back-end spectrometers that one will need in equal large numbers as pixels.

A second rationale is to that for future space Submm/THz heterodyne missions (OST, Millimetron) small heterodyne arrays (7+ sky pixels) are needed, where the space application dictates very similar requirements on low power consumption, efficient LO injection, advanced integration levels, etc.

The desired outcome of the workshop is that we have strategies for the optimum sky sampling depending on the size of the array, efficient LO distribution and injection schemes and a road map to tackle power consumption in the FPU and back-end spectrometers. The outcome is also meant as input for the design of the heterodyne instruments for the two space missions that are now under study.

This workshop is sponsored by an international collaboration between NWO and FAPESP on astronomical instrumentation.


This event has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 730562 [RadioNet].
