Declaration oflntent

on the Pre‐ Construction Phase

ofthe Cherenkov Te:escope Array(CTA)

Preamb:e丁he present generation of Cherenkov telescopes has opened a window in the domain of veryhigh¨ energy garnma― ray observations. The first deta‖

ed obseⅣ ations of the sky at TeV

energies have revealed galactic sources with complex and resolved structures in the Milky
VVay as vve‖ as numerous extragalactic sources.
、〃hich has gained an extensive knowledge with the Cherenkov
telescopes H.E.S.S.in Namibia,MAGIC on the Canary lsiands,and VERITAS in the UnitedStates,has proposed a prOiect fOr a much more senslive gamma¨ ray obseⅣ atory with fu‖
sky coverage in the energy range between severa1 10 GeV up to 300 TeV,the Cherenkov
Telescope Array(CTA).
丁he scientific cornrnunity,

丁he CTA Consortium has the amblion to provide the science communly vvith a wo‖

dwide

unique and technica‖ y innovative ground― based lmaging Atrnospheric Cherenkov Telescope
systern, with a high potential for discoveries owing to its largely improved sensitivity andspaJal resolulon CTA,as an open obseⅣ atory,will seⅣ e a wide astrophysics community
and wi‖ provide a deep insightinto the non― therrnal high¨ energy universe,enab‖ ng scientists

to tackle a variety of fundamental open questions concerning supernovae,compact obiectS
such as pulsars and black holes,the galactic centre, star forrning regions, active galactic

nuclei,dark matter,quantum gravly,charged cosmic rays,and many other suttects.
Most, if not a‖roadmaps, rnention CTA as the coming infrastructure for gamrna¨rayastronomers,for:nstance,the ASPERA and ASTRONET roadmaps,the ESFRl roadmap,
and national roadmaps of rnost ofthe participating countries.

A CTA Preparatory Phase(hereinafter referred to as CttA‐ PP)with the involvement of alarge number of European institutes is currently funded for 3 years(2010‑2013)within theSeventh Framework Programme ofthe European Union.
Based on the very promising developments so far and the size of the coHaboration ofinternalonal partners which involves more than 125 insltutes(hereinafter referred to as
CTA Consortium"),the Signato‖ es of this Declaration oflntent decided to enterinto the Pre―
construclon Phase ofthe CttA prQject(hereinafter referred to as

CTA‐ PCP")

Ministries and Funding Agenciesl ―By signing this Dec!aration of lntent,the signatories―
wish to express their cornrnon interest in participating in the construction and operation of

CttA. They agree to work together to develop an internationa1 9overnance structure andfunding scheme, and to elaborate a‖
