NEWSLETTERof the International Consortium“Development of High-Power Terahertz
Science & Technology”
October 2015

№1

LEADING NEWSWe are glad to announce that after an extended period of detailed
discussions, considerations and negotiations the final version of theAgreement for establishing an International Consortium for“Development of High-Power Terahertz Science and Technology” was signed by all participating institutions in October, 2015.
The International Consortium includes 13 institutions from 9
countries around the world as shown in the map below. It has beenorganized by the Research Center for Development of Far-Infrared
Region at the University of Fukui (FIR UF), Japan, which serves as afacilitator and a managing organization of the Consortium.

The International Consortium will maintain a website (visit:
http://fir.u-fukui.ac.jp/Website_Consortium) and will issue periodicallya Newsletter. We plan to update regularly the information presented in
the website and the Newsletter. Any contribution to both media fromthe participating institutions would be highly appreciated. It is believedthat through the joint efforts of all parties involved they will become
valuable sources of information about the research projects and otheractivities carried out by the Consortium.
WELCOME ADDRESSNOWADAYS, we are witnessing a remarkableprogress in the development of the terahertz
science and technology, which is termed bymany as a revolution that is taking place in aregion of the electromagnetic spectrum situated between microwaves
and light and thus between electronics and photonics. Till recently, andoccasionally even today this region is called “a THz gap”. In the recentyears, however, many novel high-power radiation sources that operate
in the sub-THz and the THz frequency bands have been developed.
Among them are the gyrotrons – the most powerful sources ofcoherent radiation in a CW (continuous wave) regime. They haveopened the road to many new applications in both the fundamental
physical research and the technologies. Some remarkable examples areadvanced spectroscopic techniques (e.g. NMR-DNP, XDMR, ESR,
measurement of the HFS of positronium), novel medical technologies,
detection of concealed radioactive materials, treatment and analysis ofvarious: materials etc.
The FIR UF has always been an active promoter of the international
collaboration in all these rapidly developing fields. Following thesuccess of the previous International Consortium called “Promotinginternational collaboration for development and application of submillimeter gyrotrons” we decided to renew it in an extended format.
The new International Consortium for “Development of High-PowerTerahertz Science and Technology” includes 13 institutions from 9

countries from all over the world. The activities of the Consortium will
be presented in a website and in a Newsletter, which will be publishedregularly.
We believe that in the framework of such wide collaboration theparticipating institutions will contribute significantly for the further
advancement of the high-power terahertz science and technology.
Welcoming all members of the Consortium we wish them manysuccessful research projects and remarkable results.

DISCUSSION

Our mission and goals formulated in the Agreement forestablishing the International Consortium for “Development of HighPower Terahertz Science and Technology” are represented
symbolically in the logo of our organization (see the front page of theNewsletter). In it, the V-shaped element symbolizes the region of theelectromagnetic spectrum, which is still referred to as a “THz gap”.
This “no man’s land” is situated between the microwaves and light andthus is a cliff that separates two adjacent brinks, namely electronics
and photonics (see the right and the left elements of the logo). We
consider both the THz science and technology as foundations (bottomsemi-circle) for building a bridge (upper semi-circle of the logo) overthe THz region. Our focus is just in the middle of this region, i.e.
around 1 THz. Symbolically, this target is represented by the central
element.
We intend to place the logo of the International Consortium on thewebsite. Other symbols are the logos and national flags of theparticipating institutions shown around the world map (see the firstpage).
We would like to receive a feedback from the members
concerning the mentioned graphical symbols. Please examine andcheck them carefully. Any suggestion for their correction or
improvement is welcome and would be highly appreciated.
ANNOUNCEMENTThe FIR UF is currently seeking an excellent candidate for a
postdoctoral fellow position in the field of high-power THz scienceand technology, which will be opened from the beginning of the next
academic year (April, 2016). For more details please contact:

EDITORIAL POLICY OF THE NEWSLETTERIn the following issues of the Newsletter we intend to extend its scopeand plan to include the following topics:
 Research highlights presenting new projects pursued by themembers of the Consortium.
 News from the participating institutions.
 Information about conferences, symposia, workshops, seminars.
 Programs and frameworks for exchange of visits and mobility ofresearchers.
 Annotations of books, conference proceedings, software andInternet resources. A list of the recent scientific publications andconference reports will be available from the corresponding page of
the website of the Consortium.
 Information and announcements about awards and nominations.
 Short presentations of laboratories and research groups belonging
to the participating institutions.
We encourage the researchers from the member institutions tocontribute to the Newsletter with materials, ideas and suggestions. We
believe that together we can make it a helpful and interesting source of
information about our collaboration.
