Gamma-ray Astronomy: Site negotiations for Cherenkov Telescope Array started

14.04.2014

Decision on the southern site of CTA at the end of the year

Chile and Namibia as well as Argentina as a third option have been selected from the candidates on the southern hemisphere for concrete negotiations. This has now been decided by representatives of the funding countries based on the recommendations of an independent site selection committee.

On the 10th April 2014, the 12 country delegates mandated by their governments to decide about the start of site negotiations for CTA met in Munich. They took note of the report of the international Site Selection Committee (SSC) and thanked the members of the SSC as well as the CTA consortium for their extensive inputs on the merits of the proposed sites.

The delegates representing Argentina, Austria, Brazil, France, Germany, Italy, Namibia, Poland, Spain, South Africa, Switzerland and the UK decided, based on the 75% majority required, to start the negotiations on the two sites in the southern hemisphere, namely Aar in Namibia and ESO* in Chile, keeping Leoncito in Argentina as a third option. After negotiations finally one site will be selected at the end of the year. With the selection of the potential telescope sites in the southern hemisphere an important step towards the realization of the international Cherenkov Telescope Array has been made.

As far as the northern site of the CTA Observatory is concerned – candidate sites are located in Mexico, Spain and the USA - further considerations are necessary.Therefore, the delegates decided to postpone their decision and to ask the CTA board of agency representatives – the Resource Board - to take this forward.The decision for the negotiations about the northern hemisphere site will be taken as soon as possible.

“We are very happy that this important step has been reached” said B. Vierkorn-Rudolph, chair of the CTA Resource Board. “CTA will be a unique large-scale infrastructure for astronomy - with this decision we now can start the negotiations with the potential site countries in the southern hemisphere and advance the implementation of CTA”. The spokesperson of the CTA Consortium, Professor Werner Hofmann said “The site choice is on the critical path towards implementing CTA; this decision represents a major step forward and we appreciate very much the engagement and support of the funding agencies and the country delegates involved in the decision”.

CTA – the Cherenkov Telescope Array – is a multinational, world-wide project to construct a unique instrument exploring the cosmos at the highest photon energies. Over 1000 scientists and engineers from 5 continents, 28 countries and over 170 research institutes participate in the CTA project. CTA will provide an order-of-magnitude jump in sensitivity over current instruments, providing novel insights into some of the most extreme processes in the Universe.

CTA will consist of over 100 Cherenkov telescopes of 23-m, 12-m and 4-m dish size located at one site in the southern and a smaller site in the northern hemisphere. Potential candidate sites have been identified in the northern and southern hemisphere. Extensive studies of the environmental conditions, simulations of the science performance and assessments of costs of construction were conducted. The Site Selection Committee, composed of international experts in the evaluation of sites for astronomical observatories, has reviewed the studies and provided an independent assessment of the various candidate sites.

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
