TOWARDS SUPERSENSITIVE BOLOMETERS AND ELECTRON COOLERS BASED ON CARBON NANOTUBES M.TARASOV, J.SVENSSON, S.DITTMER, L.KUZMIN, AND E.CAMPBELL Chalmers University of Technology, GЖteborg SE 41294, Sweden E-mail: Mikhail.tarasov@mc2.chalmers.se Carbon nanotubes (CNT) are being intensively developed for novel electronics. Electron cooling by superconductor-insulator-nanotube (SIN) tunnel junctions could be extremely effective due to the small volume of the CNT. ...

NATIONAL ASTRONOMY AND IONOSPHERE CENTER . ... Astronomy . ... Visitor Center . ... Optical . Lidar . At Arecibo we have a variety of optical instruments that we use to study terrestrial airglow emissions. ... This equipment is located in our Optical Laboratory, which is on site about 1000 feet from the center of the incoherent scatter radar. ... The various observational modes that are available are described in supplementary documentation for the Arecibo Observatory Optical Laboratories. ...

Astronomy Picture of the Day . ... Spanning about 1/2 degree on the sky, the pretty picture is the result of astronomer Johannes Schedler's project to look back in time, toward a quasar 12.7 billion light-years away . ... Of course, the expansion of the Universe has redshifted the light. Schedler added image data extending to the near-infrared, acquired by collaborator Ken Crawford, to detect the distant quasar, with a measured redshift of 6.04. ... Publications with keywords: quasar - redshift . ...

... We describe efforts to develop a robust fabrication technology for making submillimeter detectors integrated with single electron transistors as readout amplifiers. ... Thus, the RF-SET can amplify the small photocurrent generated in a superconducting tunnel junction detector by a single submillimeter photon. ... The antenna, detector, and SET are contained in 4 fields, which are fabricated with electron beam lithography and Al double angle evaporation techniques. ... FABRICATION OF SQPC CHIP . ...

... Despite new observation methods provided by radar and satellite instrumentation , optical measurements are still important when studying auroras . ... Because of the monochromatic nature of the auroral light, photomultiplier tubes with very narrow band filters were used in the measurements. ... The spectra of the background emissions from atmospheric impurities (clouds, ice crystals, etc.) is rather continuous, and measurements just outside the auroral emission lines are valid for the line itself. ...
