In the context of the HL-LHC project, a NbTi double aperture quadrupole magnet called MQYY is being developed. This 90 mm aperture quadrupole magnet has a magnetic length of 3.67 m and an operating gradient of 120 T/m at 1.9 K. Its development is done along two parallel paths: 1) the design, fabrication and test of a short model, 2) the design and fabrication of two full scale prototypes in industry within the H2020 EU Pre-Commercial Procurement project QUACO implemented by CERN, CEA, CIEMAT and NCBJ. We report here on the short-model design choices, the status of its fabrication and the preparation of the tests. In particular, we describe the magnetic and mechanical design relying on self-supporting collars, the protection aspects and the assembly process. In addition, we present the unusual scheme of the QUACO project leading to the prototypes fabrication.
The QUACO project has received funding from the European Union’s Horizon 2020 PCP programme under Grant Agreement no. 689359
