CALIBRA Phase 1 refers to the downscaled CALIBRA RI imposed initially by the ministerial decision of August 2016, according to which the budget of all NRIs of the updated Roadmap could not exceed 4 million Euros, and the subsequent budget reduction due to CALIBRA’s fourth evaluation of July 2017.
In CALIBRA Phase 1, implemented through the CALIBRA Project , the purchase of a brand new 6 MV Tandem accelerator was replaced by the full-upgrade of the existing 5.5 MV Tandem and the procurement of a new 4 MV single-stage accelerator with an ECR source as well as the purchase of a new accelerator for Accelerator Mass Spectrometry (AMS) were, essentially, excluded. Moreover, the funds for a new building to host the donated 17 MeV Cyclotron together with a laboratory for PET radiopharmaceuticals were removed and only the transport costs of the cyclotron from Groningen to Athens remained. Meanwhile the cyclotron, a unique instrument for R&D in Greece, is now at the CALIBRA’s premises.
In 2019, the Institute of Archaeology of the University of Oxford donated its 2.5 MV Tandetron Accelerator for Accelerator Mass Spectrometry (AMS) to CALIBRA. This donation provided Greece with a unique scientific tool, especially because of the country’s very rich cultural heritage, and gave new momentum towards the implementation of the Full-Scale CALIBRA RI. The donated AMS accelerator was transferred to CALIBRA premises in October 2022.
