Design of the ANTHEM RFQ mechanical supports

The ANTHEM (Advanced Technologies for Human-centered Medicine) research project will establish a Research and Clinical Center in Caserta, Italy, for the study and application of Boron Neutron Capture Therapy (BNCT). The INFN (LNL, Pavia, Napoli, Torino) has in charge the design and construction of the epithermal neutron source, that will assure a flux of $10^9\ n/(s\ cm^2)$ with characteristics suited for deep tumors treatment. The Radio-Frequency Quadrupole (RFQ), designed by INFN, produces $30\ mA$ of protons at $5\ MeV$ and is composed of 3 super modules, each of which at $600\ kg$ in weight and $2.5\ m$ in length. The supports perform the iso-statical alignment during the modules assembly, coupling and alignment, and are also used to align the RFQ respect to the Nominal Beam Line, using a Laser Tracker to monitor the position with a tolerance of $0.1\ mm$. This paper details the chosen kinematic configuration, the supports design, the calculation and simulations for design validation, the procedures for regulation and alignment and the achieved results.
