The CTA Construction Project
According to the CTA Declaration of Intent, three major reviews are the basis for CTA Construction approval:
- The Science Performance and Preliminary Requirement Review (SPPRR)
- The Preliminary Design Review (PDR)
- The Critical Design Review (CDR)
The reviews are conducted by the Resource Board-appointed Scientific and Technical Advisory Committee (STAC), which monitors and evaluates the scientific goals and assesses the overall model for CTA, including its technical design. The SPPRR was successfully completed in February 2013 and the PDR was concluded in November 2013, on the basis of the Preliminary Technical Design Report.
A high-level work breakdown structure is illustrated in the below figure. The diagram covers all phases of the project (see project timeline below), but some activities (e.g. site negotiations) are only relevant to particular phases.
Construction Project Timeline
The build-up to construction continues in 2016 with first telescopes on
site expected in early 2017. In the mean time, we'll be finalizing site
negotiations, our finances and preparing the sites for construction.
The timeline below illustrates the three major project phases, our progress
along the pre-construction phase timeline and tentative future schedule.Site Selection
On 15 and 16 July 2015, the Cherenkov Telescope Array
(CTA) Resource Board decided to enter into detailed contract negotiations for
hosting CTA on the European Southern Observatory (ESO) Paranal grounds in Chile
and at the Instituto de Astrofisica de Canarias (IAC), Roque de los Muchachos
Observatory in La Palma, Spain.
The Board, composed of representatives of ministries and
funding agencies from Austria, Brazil, the Czech Republic, France, Germany,
Italy, Namibia, the Netherlands, Japan, Poland, South Africa, Spain,
Switzerland and the UK, decided after months of negotiations and careful
consideration of extensive studies of the environmental conditions, simulations
of the science performance and assessments of construction and operation costs
to start contract negotiations with ESO and Spain. The Namibian and Mexican
sites will be kept as viable alternatives.
site is less than 10 km southeast of ESO’s existing Paranal Observatory in the
Atacama Desert, which is considered one of the driest and most isolated regions
on earth – an astronomical paradise.
northern site is located on the existing site of the Instituto Astrofisica de
Canarias Observatorio del Roque de los Muchachos on the island of La Palma, the
fifth largest island in the Canary Islands.
