Forming limit diagram of annealed copper OFE thick sheets for optimized hydroforming of superconducting RF cavities / Gallifa-Terricabras, Adrià (CERN) ; Swieszek, Joanna Sylwia (CERN) ; Smakulska, Dorota (CERN) ; Ruiz-Palenzuela, Berta (CERN) ; Garlaschè, Marco (CERN)
Coated superconducting radio-frequency (SRF) cavities are planned to be implemented in the Future Circular Collider (FCC) at the European Organization for Nuclear Research (CERN). The interest in industrialized and high-performance processes for fabrication of the corresponding copper substrates has thus risen. [...]

Novel Approaches in Characterization and Modelling of Fabrication Processes for SRF Components / Swieszek, Joanna (CERN ; U. Heidelberg (main)) ; Gallifa Terricabras, Adrià (CERN) ; Garlasché, Marco (CERN) ; Smakulska, Dorota (CERN)
In the past years, Finite Element Methods have been increasingly applied at CERN, with the aim of modelling fabrication processes for SRF components. Currently, many large deformation processes such as deep drawing, forging, hydroforming, and spinning, are being simulat-ed. [...]

Optimizing the Manufacture of High-Purity Niobium SRF Cavities Using the Forming Limit Diagram: A Case Study of the HL-LHC Crab Cavities RFD Pole / Gallifa Terricabras, Adrià (CERN) ; Aviles Santillana, Ignacio (CERN) ; Barrière, Simon (CERN) ; Cano-Pleite, Eduardo (Carlos III U., Madrid) ; Garlasché, Marco (CERN) ; Narduzzi, Manuele (Fermilab) ; Pfeiffer, Stephan (CERN) ; Prever-Loiri, Laurent (CERN) ; Swieszek, Joanna (CERN ; U. Heidelberg (main))
The Crab Cavities are key components of the High Luminosity Large Hadron Collider (HL-LHC) project at CERN, which aims to increase the integrated luminosity of the LHC, the world’s largest particle accelerator, by a factor of ten. This paper explores the application of the Forming Limit Diagram (FLD) to enhance the manufacturing process of complex-shape Nb-based cavities, with a focus on the formability challenges experienced with the pole of the Radio Frequency Dipole (RFD) Crab Cavities.

Flux Expulsion Lens: Concept and Measurements / Koettig, T (CERN) ; Turner, Daniel (CERN) ; Gallifa Terricabras, Adrià (CERN) ; González Díaz-Palacio, Isabel (U. Hamburg (main)) ; Hillert, Wolfgang (U. Hamburg (main)) ; Koettig, Torsten (U. Hamburg (main)) ; Macpherson, Alick (CERN) ; Rosaz, Guillaume (CERN) ; Stapley, Niall (CERN) ; Wenskat, Marc (U. Hamburg (main))
A magnetic flux expulsion lens (MFEL) has been designed and built at CERN. This device uses closed topology conduction cooling of samples to quantify magnetic flux expulsion of superconductors, and allows for systematic measurements of the cooling dynamics and the magnetic response during the superconducting transition.

HOM Couplers and RF Antennas for HL-LHC Crab Cavities: Developments for Manufacturing / Barrière, Simon (CERN) ; Atieh, Said (CERN) ; Bulat, Bartosz (CERN) ; Calaga, Rama (CERN) ; Calvo, Sebastien (CERN) ; Capatina, Ofelia (CERN) ; Demazière, Thomas (CERN) ; Favre, Gilles (CERN) ; Gallifa Terricabras, Adrià (CERN) ; Garlasché, Marco (CERN) et al.
Superconducting RF crab cavities are being manufactured as part of the High-Luminosity LHC project at CERN. Amongst its related ancillaries, radiofrequency HOM (High Order Modes) couplers and field antennas are essential for reaching nominal performance during operation with high energy beams, as they monitor and control the electromagnetic fields in the cavities.

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. [...]
