This consultation concerns the acquisition, delivery and installation of a cryogen-free system accompanied by two cryogenic warheads, adapted to two different experimental situations.

In both cases, the experiments will fall within the field of TeraHertz spectroscopy (in the range 0.2 to 6 THz). The cryostat must therefore be compatible with interchangeable windows, in particular transparent polymer in the TeraHertz range. These experiments will be carried out over a temperature range from 5 to 300 K.

This contract follows consultation No. 202304131740 which was declared unsuccessful.

The contract holder will contact the recipient of the services, as indicated in the consultation documents, in order to agree with him on a specific date and time of delivery. Delivery may take place from Monday to Friday from 9:00 to 12:00 and from 14:00 to 16:00, except holidays, and unless expressly authorized by the recipient of the services.

The installation of the equipment is planned on the microwave platform of the IEMN. The contract holder will provide the list of the various necessary easements (electricity, fluids, etc.) as well as the dimensions of the different parts of the system.
