Ex-situ Tunnel Junction Process Technique Characterized by Coulomb Blockade Thermometry
M. Prunnila, M. Meschke, D. Gunnarsson +3
We investigate a wafer scale tunnel junction fabrication method, where a plasma etched via through a dielectric layer covering bottom Al electrode defines the tunnel junction area.…
Planck pre-launch status: calibration of the Low Frequency Instrument flight model radiometers
F. Villa, L. Terenzi, M. Sandri +71
The Low Frequency Instrument (LFI) on-board the ESA Planck satellite carries eleven radiometer subsystems, called Radiometer Chain Assemblies (RCAs), each composed of a pair of pse…
Acoustic Phonon Tunneling and Heat Transport due to Evanescent Electric Fields
Mika Prunnila, Johanna Meltaus
The authors describe how acoustic phonons can directly tunnel through vacuum and, therefore, transmit energy and conduct heat between bodies that are separated by a vacuum gap. Thi…
Design, development, and verification of the Planck Low Frequency Instrument 70 GHz Front-End and Back-End Modules
J. Varis, N. J. Hughes, M. Laaninen +26
70 GHz radiometer front-end and back-end modules for the Low Frequency Instrument of the European Space Agencys Planck Mission were built and tested. The operating principles and t…
Advanced modelling of the Planck-LFI radiometers
P. Battaglia, C. Franceschet, A . Zonca +22
The Low Frequency Instrument (LFI) is a radiometer array covering the 30-70 GHz spectral range on-board the ESA Planck satellite, launched on May 14th, 2009 to observe the cosmic m…
Thermal susceptibility of the Planck-LFI receivers
L Terenzi, M J Salmon, A Colin +33
This paper is part of the Prelaunch status LFI papers published on JINST: http://www.iop.org/EJ/journal/-page=extra.proc5/jinst . This paper describes the impact of the Planck Low…
