Royal Netherlands Meteorological Institute (KNMI)

The Royal Netherlands Meteorological Institute (KNMI) is the Dutch national weather service. Primary tasks of KNMI are weather forecasting and monitoring of weather, climate, air quality and seismic activity. KNMI is also the national research and information centre for meteorology, climate, air quality, and seismology.

KNMI advises on and warns society to reduce risks in the field of weather, climate and seismology and to limit damage and injuries. With high-quality knowledge and technology plus an extensive observation network, KNMI offers products and services that contribute to the safety, accessibility, sustainability and prosperity of the Netherlands.

The department R&D Seismology and Acoustics (R&DSA) covers the field of mechanical waves in the solid earth, the atmosphere and the oceans, from the angles of seismology and acoustics. The department is responsible for the real-time determination of the epicenter, the strength and the depth of both tectonic and induced seismic events in the Netherlands, and the attribution of their causes. To this end data are acquired (monitoring using an extensive national seismic and acoustic network), interpreted (analysis and research) and distributed (data dissemination).

Within the E-TEST project, R&DSA will set up a seismic monitoring network in the region of interest. This network complements the already existing seismic instrumentation in the area. Acquired data will be used to image the subsurface and estimate the background noise levels at depth from surface and borehole measurements.

Maastricht University

The Department of Gravitational Waves and Fundamental Physics (GWFP) at Maastricht University (UM) was established in 2019. Its members, however, have been active in the field of gravitational wave astronomy for a long time and hold several key positions within the LIGO and Virgo collaborations.

Maastricht University is the most international university in the Netherlands. UM has quickly built up a solid reputation as a result of its high-quality research and education, as well as a strong focus on social engagement. Today, UM is considered one of the best young universities in the world. It is located in the Limburg region of the Netherlands, which has been selected as a possible location for the future European gravitational-wave detector, the Einstein Telescope (ET).

The GWFP group aims at developing and testing key technologies for ET in the regional and European context. Its expertise lies especially within the optical interferometer design, the application of novel quantum technologies for increased sensitivities and the development of new highly-reflective mirror coatings. A prototype interferometer facility is currently being built at UM which will serve as a unique testing and integration platform for regional and international partners.

Within E-TEST, the group will contribute its expertise on interferometer design and requirements to the development of large, cryogenically cooled mirrors that are to be used as test-masses in ET. Specifically, GWFP has two PostDoc positions within E-TEST, who will work on the large-scale silicon test-masses with a focus on the dielectric mirror coating, as well as the noise requirements and characterisation for the to-be developed laser source at a wavelength of 2µm.
