Lumped Parameter Model for Structural Analysis of Over-Constrained Multi-Legged Parallel Mechanism Supporting System Applied to Cryogenic Devices / Piacentini, Luca (Riga Tech. U.) ; Dassa, Luca (CERN) ; Perini, Diego (CERN) ; Ratkus, Andris (Riga Tech. U.) ; Torims, Toms (Riga Tech. U.) ; Uberti, Stefano (U. Brescia)
While the design of a cryostat is being developed, one of the most relevant sub-systems is the internal supporting system that sustains the cooled component. According to the literature, the arrangement and number of supports chosen often result in a multi-leg over-constrained architecture. [...]

Design of a 6-supports exactly constrained supporting system for superconducting magnets and its application to rotating gantries for cancer therapy / Piacentini, Luca (CERN ; Riga Tech. U.) ; Dassa, Luca (CERN) ; Perini, Diego (CERN) ; Ratkus, Andris (Riga Tech. U.) ; Torims, Toms (Riga Tech. U.) ; Uberti, Stefano (U. Brescia)
In particle therapy for cancer treatment, the radiation dose to tissues around the tumour can be reduced by employing a rotating gantry—a mechanical structure allowing the delivery of the particle beam to the patient from various angles. Gantries for ion therapy can benefit from the integration of superconducting magnets to minimize the size and weight of the machine. [...]

Literature Review of Suspension Systems for Superconducting Elements / Piacentini, Luca (Latvia U., ISSP) ; Dassa, Luca (CERN) ; Perini, Diego (CERN) ; Ratkus, Andris (Latvia U., ISSP) ; Torims, Toms (Latvia U., ISSP) ; Uberti, Stefano (U. Brescia)
When designing suspension systems for superconducting elements, the primary challenge is to strike a balance between limiting the heat load to the cold mass and ensuring the proper mechanical resistance and/or stiffness of the system. This trade-off often leads engineers to choose from a limited set of materials and supporting architectures. [...]

Preliminary Design of the Support Structure for a Rotating Carbon-Ion Transfer Line for Medical Applications / Perini, Diego (CERN) ; Dassa, Luca (CERN) ; Piacentini, Luca (Riga Tech. U.) ; Uberti, Stefano (Brescia U.)
The development of new bent superconducting magnets together with the optimization of the support structure open the way to a considerable reduction in the weight and complexity of rotating gantries for medical applications. The magnets, which define the transfer line to deliver carbon ions to the patients from different angles, are supported by a rotating structure that should be as rigid and as lightweight as possible.

An Insight on the Thermal and Mechanical Numerical Evaluations for the High-Luminosity LHC Crab Cavities / Cano-Pleite, Eduardo (CERN) ; Amorim Carvalho, Alexandre (CERN) ; Artoos, Kurt (CERN) ; Calaga, Rama (CERN) ; Capatina, Ofelia (CERN) ; Capelli, Teddy (CERN) ; Carra, Federico (CERN) ; Dassa, Luca (CERN) ; Garlasché, Marco (CERN) ; Leuxe, Raphael (CERN) et al.
One of the key devices of the HL-LHC project are SRF crab cavities. A cryomodule with two Double Quarter Wave (DQW) crab cavities has been successfully fabricat-ed and tested with beam at CERN whereas the Radio Frequency Dipole (RFD) crab cavities are currently on its fabrication process. [...]
