An enhanced Racetrack Model Coil (eRMC) using Nb3Sn superconductor was built at CERN; an important step in the road to a final prototype of a 16T magnet for the 100 TeV future circular proton collider.
Researchers and industrial partners from Europe, USA, Russia, Japan and Korea push the limits of superconductors and develop new techniques that could allow large-scale industrialization of the technology. In parallel, high-temperature superconductors materials given their potential impact in HEP and beyond.

Preliminary design of a future detector for a precision-frontier lepton circular collider (FCC-ee). Two different concepts are currently under development profiting from global synergies and joint R&D efforts. 
First prototype of a dipole magnet for a future lepton collider (FCC-ee). Thanks to the most efficient design compared to the magnets previously used at LEP an energy saving of 20-30% is possible. The magnet was built and tested at CERN. 
FCC-ee quadrupole test magnet installed on the magnetic measurement bench in the laboratory 311 at CERN. The magnetic coupling between the two apertures brings a 50% saving in power consumption with respect to a traditional design

The photo shows one of the first prototypes produced for the FCC beam screen system. A robust beam screen system is key to cope with the more energetic beams of FCC and to ensure high-vacuum conditions. Currently prototypes are tested and the first results will inform the final design.

The kick-off meeting of the FCC study took place in 2014 in the University of Geneva. Four years after the FCC collaboration successfully submitted its four-volume CDR; a collective work of more than 1300 contributors from 135 universities in 35 countries. 
Drawing of TEVATRON, LEP & LHC and the foreseen plans for a future circular collider in a 90-100 km tunnel.
You can see the circumference of each of these circular colliders as well as the energy reach for different types of particle collisions.
Cryogenic and cooling technologies are key for the successful operation of a future energy-frontier collider. More efficient cryogenics and new coolants are explored in collaboration with research centres and universities and the early involvement of the industry. EuroCirCol and EASITrain H2020 projects also support the activity on high-performant cryogenic refrigeration; a technology with many applications outside particle physics. 
Sarah Aull is one a CERN Fellow working in the development of Superconducting RF cavities. The FCC study provides a number of opportunities for training - particularly in the novel technologies that are currently tested - to young scientists and engineers. 
The FCC study prepared a conceptual design of a 100km long ring accelerator, that uses CERN's existing accelerator infrastructure. 
The photo shows one of the techniques used for thin-film coating of surfaces (ie. magneto-spattering). Of special interest is the application for covering RF copper cavities with a thin superconducting layer that could boost their efficiency. Further developments of this technique could allow the large-scale production of superconducting RF cavities which can then find application in the industry, medical field and even in quantum computing.

An important aspect of designing future accelerators that will reach higher-energy frontiers is the further improvement of RF cavities, which are used to accelerate charged particles.
The study of superconducting radio-frequency (SRF) cavities remains one of the most active fields of research, given the global interest for accelerators capable of accelerating different species of particles with higher efficiency. SRF cavities are also essential for numerous applications that accelerators find in industry, medical imaging and treatment, as well as for future promising applications.
The photo shows a Nb3Sn Rutherford cable for high-field magnets to be used in HL-LHC as well as for future colliders covered by the FCC study.
A crucial first step in the development of new superconducting materials is the specification and purchase of significant quantities of high performance material for assembly into cables for use in the Hi-Lumi magnets that will be an important milestone paving the way for using this material in future circular colliders. 
High-efficiency RF cavities require novel production techniques to achieve seamless surfaces and reduce impurities.
