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. [...]

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. [...]

Tech.) ; Bogacz, Alex (Jefferson Lab) ; Bousson, Sébastien (Orsay, IPN) ; Brüning, Oliver (CERN) ; Calaga, Rama (CERN) ; Chaikovska, Iryna (Orsay, LAL) ; Dassa, Luca (CERN) ; Gerigk, Frank (CERN) ; Hounsell, Benjamin (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech. ; Orsay, LAL) et al.
PERLE is a proposed high power Energy Recovery Linac, designed on multi-turn configuration, based on SRF technology, to be hosted at Orsay-France in a collaborative effort between local laboratories: LAL and IPNO, together with an international collaboration involving today: CERN, JLAB, STFC ASTeC Daresbury, Liverpool University and BINP Novosibirsk. PERLE will be a unique leading edge facility designed to push advances in accelerator technology, to provide intense and highly flexible test beams for component development. [...]

Assessment of the Mechanical Properties of Ultra-High Purity Niobium after Cold Work and Heat Treatment with the HL-LHC Crab Cavities as Benchmark
/ Gallifa Terricabras, Adria (CERN) ; Amorim Carvalho, Alexandre (CERN) ; Aviles Santillana, Ignacio (CERN) ; Barriere, Simon (CERN) ; Calaga, Rama (CERN) ; Cano Pleite, Eduardo (CERN) ; Capatina, Ofelia (CERN) ; Crouvizier, Mickael Denis (CERN) ; Dassa, Luca (CERN) ; Meyer, Mickael Sebastien (CERN) et al.
The High Luminosity Large Hadron Collider (HL-LHC) is the upgrade of the world’s largest particle collider; it will allow the full exploitation of the LHC potential and its operation beyond 2025. An essential part of the HL-LHC project are the Crab Cavities, that are particle de-flecting SRF cavities of non-axisymmetric shape made of bulk ultra-high purity Nb. [...]

Sub-micro-Tesla Magnetic Shielding Design for Cryomodules in the High-gradient Program at CERN
/ Papadopoulos, Sotirios (CERN) ; Dassa, Luca (CERN) ; Dequaire, Julien (CERN) ; Gerigk, Frank (CERN) ; Pillon, Francois (CERN) ; Ramberger, Suitbert (CERN) ; Yilmazer, Pinar (CERN)
In the framework of the High-Gradient R\&D; program at CERN a cryomodule, consisting of four superconducting 5-cell cavities, has been designed. In order to reduce flux trapping in the surface of the superconductor and to minimize Q degradation during a quench, highly effective magnetic shielding is needed. [...]
