Validation loading tests for the first HL-LHC jacks produced by UNIOR components d.o.o, a Serbian Company. They are part of an order for nineteen longitudinal jacks and four central jacks that will be used to support the magnets in the IT String configuration and for validation purposes in terms of design, stress and irradiations.

These initial load tests are part of the Factory Acceptance Tets performed at UNIOR's premises in Kragujevac, with the presence of CERN experts, before the delivery of the first 4 units to CERN.
