Contribution

It introduces the MUSICAM multicolor subTHz MKID-array camera concept and discusses its instrumental testing as a foundation for Eurasian SubMillimeter Telescopes development.

Findings

Successful demonstration of MUSICAM camera prototype

Validation of multicolor subTHz MKID technology

Feasibility of large-format arrays for future telescopes

Abstract

New challenges in submillimeter wave astronomy require instruments with a combination of high sensitivity and angular resolution, wide field of view and multiwave (multicolor) spectral range. New large single mm/submm telescopes are in high demand, as well as their inclusion in the global Event Horizon Telescope (EHT) VLBI network. At the same time, there are no large mm/submm telescopes in Asia at all while appropriate sites exist and their appearance in Asia or Eurasia is long overdue. Kinetic inductance detectors (KID) are ideal for large-format array implementation, which will be necessary for future telescope development. Concept of multicolor subTHz KID-array MUSICAM demo camera and its instrumental testing is given. It allows us to perform some necessary steps toward the creation of the Eurasian SubMillimeter Telescopes (ESMT), which concept and scientific tasks are presented as well.
