In-flight calibration of ESA Hera's HyperScout-H imager
G. P. Prodan, M. Popescu, J. de León +21
ESA's Hera space mission is on its way to the mission target, the binary asteroid (65803) Didymos. HyperScout-H, one of the instruments onboard Hera, is a hyperspectral imager oper…
HyperScout-H: the hyperspectral imager for the ESA Hera mission
Marcel M. Popescu, Julia de León, George Pantelimon Prodan +16
The HyperScout-H (HS-H) instrument is one of the payloads aboard ESA's Hera spacecraft. Hera is a planetary defence mission that aims to provide a detailed characterization of the…
4x2 Hot electron bolometer mixer arrays for detection at 1.46, 1.9 and 4.7 THz for a balloon borne terahertz observatory
José R. G. Silva, Wouter M. Laauwen, Behnam Mirzaei +10
We have demonstrated three 4x2 hot electron bolometer (HEB) mixer arrays for operation at local oscillator (LO) frequencies of 1.46, 1.9 and 4.7 THz, respectively. They consist of…
Evanescent states and non-equilibrium in driven superconducting nanowires
N. Vercruyssen, T. G. A. Verhagen, M. G. Flokstra +2
We study the non linear response of current-transport in a superconducting diffusive nanowire between normal reservoirs. We demonstrate theoretically and experimentally the existen…
Reduced frequency noise in superconducting resonators
R. Barends, N. Vercruyssen, A. Endo +4
We report a reduction of the frequency noise in coplanar waveguide superconducting resonators. The reduction of 7 dB is achieved by removing the exposed dielectric substrate surfac…
Minimal resonator loss for circuit quantum electrodynamics
R. Barends, N. Vercruyssen, A. Endo +6
Single photon level quality factors of 500x10^3 are shown in NbTiN superconducting resonators at millikelvin temperatures. This result originates from the intrinsic low dielectric…
