Björkliden, Kiruna, Sweden, April 17-24, 2002
Organizing Committee:
Leonid Kuzmin, Göteborg – Chairman
Tord Claeson, Göteborg
Michael Tarasov, Göteborg - Moscow

Jukka Pekola, Jyväskylä
Ann-Marie Frykestig, Göteborg
The workshop has been supported by INTAS, and STINT.
Workshop content
The general subject of the workshop/school were nonequilibrium effects
in mesoscopic structures and possible application of these effects in supersensitive
systems.
The main topics of the workshop/school
Hot-Electron Microbolometers for ultrasensitive detection of IR and submillimeter
waves; other types of sensors.
Electron cooling by SIN tunnel junctions; the problem of nonequilibrium
quasiparticles in superconductors.
Cryogenics
SQUID readout system and imaging arrays of bolometers
Quasioptics and HF Filtering
Astronomical tasks in submm/IR regions
Development of a Submillimeter Cryogenic Telescope for the International
Space Station (Project Submillimetron)
Other astronomical projects. Possible international cooperation.

progress in development of readout system: a measured SQUID sensitivity
40 fA/Hz1/2;
progress in Submillimetron: the project is accepted for implementation
by RSC Energia, a criogenic concept of the instrument is updated;
a new view of importance of the scientific objectives of the Submillimetron
after discovery of observational evidence of the reionization in early
Universe;
high importance and fundamental meaning of astronomical sky survey in general,
and actuality of ELISA and Submillimetron surveys in this decade;
remarkable progress in techniques for space and/or low-temperature research:
submillimeter integrated receivers, sorption and electron coolers, low-noise
electronics, RF-filters;
progress in international cooperation: new scientific links with France,
Holland, Denmark, Germany, and Georgia.
The recommendations of the workshop
continuing and developing an international cooperation in the following
fields:
development of bolometer fabrication in IREE and MSU in addition to
regularly acting Chalmers center;
development of regularly acting measurement centres at DTU, Lyngby, in
cooperation with Tbilisi University and at Chalmers University for dc and
high frequency bolometer qualification;
research in bolometer array electrodynamics and circuitry with ASC, IKI
in the frame of INTAS project;
SQUID readout with IPHT, Jena and VTT, Jyväskylä, MSU, IZMIRAN
in frame of INTAS project;
electron cooling, hot quasiparticles with Jyväskylä, Oslo University;
3He sorption cooling with CEA - Air Liquide, Chalmers, Jyväskylä,
Metorex;
balloon observations for bolometers tests with CESR, Esrange, Grenoble
(CEA, Archeops), IAS;
developing in 2002 the submm-photometer for demonstration tests of the
bolometer in astronomical observation with ground-based 6-m telescope BTA
(Chalmers, ASC);
developing a bolometer array (in accordance with ELISA detectors specifications)
for demonstration tests at balloon telescope (Chalmers);
installing SQUID readout system of IPHT, Jena at Chalmers for several month
of joint research in the field of noise of bolometer structures;
investigating a possibility of flight of the CNES gondola with balloon
of the Russian Aerostat Commission (ASC, LPI);
considering possible applications of a research of nonequilibrium effects
in mesoscopic structures for interstellar solid particles;
placing working material of the workshop at the Internet for exchange among
participants;
sending printed materials of the workshop to participants and to Swedish
astronomers interested in space projects;
applying the proposals on bolometric space instruments to SNSB in May 2002
(Chalmers, ASC);
including in next workshop:
a cryogenic session;
reviews of modern state of astronomical detectors and space projects;
demonstration of successful operation of the Submillimetron detectors in
presence of background;
a visit to IRF-Kiruna;
more activity of participants in preparing of workshop (printed materials
for discussions, wide participation in determination of scientific program);
carrying out the next workshop in March 22-30, 2003, Björkliden, Sweden.
The workshop participants express satisfaction with a high level of organization
of the meeting, which brought new information, and stimulated new ideas.
They mark high level of presented works and look forward to the joint research.
