The production of 6 crystals will be preceded by the synthesis of 2 crystals with the same characteristics, but made from molybdenum with a natural isotopic composition, with the aim of validating the crystallization procedure. The 8 crystals produced in this way will be installed in CROSS' cryogenic infrastructure located in the Canfranc underground laboratory in Spain in the form of bolometric particle detectors.

The purpose of this contract is the production of 6 crystals which will be preceded by the synthesis of 2 crystals with the same characteristics, but made from molybdenum with a natural isotopic composition, in order to validate the crystallization procedure. The 8 crystals produced in this way will be installed in CROSS' cryogenic infrastructure located in the Canfranc underground laboratory in Spain in the form of bolometric particle detectors.

The contract is concluded at a global and fixed price for all the services to be performed and described in the contractual documents of the contract.

The services include, at least (description of the steps to be taken in the CCTP):

- The production of the first 2 crystals containing natural molybdenum

- The production of the 6 crystals containing enriched molybdenum (mandatory after written validation of the admission of the first 2 crystals)
