Description
This first Annual Meeting of the Future Circular Collider study is an important milestone to conclude the first, exploratory phase, leading to the identification of the baseline for the further study. Organized as an IEEE conference, it will provide the opportunity for re-enforcing the cohesion of the community and to catalyse cross-fertilization within the FCC study.
This meeting also constitutes the preparatory event of the EuroCirCol H2020 project, which has been approved by the EC on January 28th, 2015. Dedicated working groups on schedule, communications and gender equality will be organised and the governance bodies will be compiled at the occasion.
The event will follow the traditional layout of plenary and parallel sessions with invited contributions. Plenary sessions will give an overview about the ongoing activities across all parts of the study and serve informing study members about the main boundary conditions and working hypothesis. Parallel sessions will focus on specific areas of the study and a limited number of contributed 10’ presentations are foreseen, to enable communication of key findings of ongoing work with significant impact on the subsequent study phases in an efficient way. We encourage submission of proposals which will be reviewed by the organising committee.
Satellite meetings for related projects and governance bodies will be included the program. Participation of industry is highly encouraged and supported via a dedicated industry track and a micro exhibition, focusing on superconducting cable technology. Communication and equal opportunity aspects will be addressed in dedicated working group meetings.
Plenary and parallel session contributions are by invitation only.
An open scientific fast track provides the opportunity to present findings of ongoing work with significant impact on the further study and of high importance to the FCC study community.

Ultraefficient superconducting RF cavities for FCCRecent Fermilab discoveries of nitrogen doping and effective magnetic flux expulsion allow quality factors in bulk niobium SRF cavities several times higher than the previous state-of-the-art from only two years ago. The combined approach using both of these techniques allows to minimize both residual and BCS surface resistances leading to the world-record quality factors of >2e11 corresponding to surface resistance of <1.5 nOhm up to the highest fields of 20+MV/m. Possibility of such high quality factors holds the potential to dramatically decrease a dynamic heat load and affect the choice of the optimal operating temperature of FCC. In this contribution I will briefly review these recent developments and outline their potential impact on the design of FCC. The plans for Fermilab Nb3Sn SRF cavity work for future 4.2K industrial (and potential FCC) applications will be discussed as well.Speaker: Alexander Romanenko (FNAL)

Advances in development of diffused Nb3Sn cavitiesRecent advances at Cornell University in the development of Nb3Sn cavities have demonstrated the huge potential of this alternative material for very high efficient SRF acceleration. Nb3Sn has a critical temperature of 18 K, approximately twice that of niobium, allowing Nb3Sn cavities to have exceptionally high intrinsic quality factor Q0—which indicates extremely small cryogenic dissipation—at a given temperature. Single cell 1.3 GHz cavities now reach medium fields with quality factors Q0 above 1E10 at 4.2K, with the potential of exceeding 4E10 at 4.2K with reduced residual resistance. At a lower RF frequency of 800 MHz, quality factors at 4.2K in the 1E11 range are possible, making Nb3Sn a very attractive option for the SRF cavities in the FCC.Speaker: Matthias Liepe (Cornell Univ.)

Interaction region designThe FCC experimental insertion region design is critical for achieving the required luminosity and to control the beam background conditions for the FCC experiments. The main goal of the starting design work is to optimise the luminosity per beam current to ensure that beam induced radiation does not compromise the experiments or affect collider operation. The design work will aim to achieve the following objectives: a) develop a baseline conceptual design of the IR, consistent with machine and detector requirements; b) specify functions and key performances of key beamline elements; c) develop a machine detector interface concept. The core design activity, within the EU funded design study, will be performed by collaboration of JAI/Oxford, STFC and Cockcroft Institute/Manchester, INFN, EPFL and CERN, in close collaboration with JAI/RHUL and many other partners. The particular design tasks of IR work package include a) development of the interaction region lattice (led by JAI/Oxford); b) design of machine detector interface (led by STFC/CI/Manchester); c) study of beam-beam interaction (led by EPFL). In this talk, after brief overview of FCC IR design goals, we will discuss the planned design approaches and present status of the work for the three components IR optical lattice, MDI and beam-beam effects. We will present the teams engaged into the study, describe their past relevant experience, available design tools, and relevant plans for team development and expansion needed for fulfilling the planned activities.Speaker: Andrei Seryi (JAI)

FCC-hh as a heavy-ion colliderLike the LHC, the FCC-hh could provide nucleus-nucleus and proton-nucleus collisions at unprecedented energies of 38.5 and 62 TeV per colliding nucleon pair. First studies have shown that an efficient new collider regime with emittance evolution governed by strong synchrotron radiation damping can be fully exploited to yield high integrated luminosity, even using the present LHC Pb beams. Upgrades to the heavy-ion injectors require further study but could yield still higher performance. If foreseen from the beginning, the modifications to the collider rings seem modest: certain requirements on the RF and beam instrumentation and some additional collimators. The advantages of switching from lead to other species are discussed. Requirements for further work are outlined.Speaker: John Jowett (CERN)

IR designs & dynamic apertureFCC-ee is an electron positron collider in the range of 90 GeV to 350 GeV central mass energy. Collider’s usual goal of achieving maximum luminosity is hindered by large amount of synchrotron radiation energy loss with chosen limit of 50 MWt per beam. The first part of the presentation compares three collision schemes: head-on (base line), small crossing angle with crab cavity, crab waist with respect to luminosity and necessary beam parameters. The second part describes interaction region lattice for crab waist collision scheme and discusses needed changes to make it suitable for other schemes. The lattice greatly depends on design of the final focus quadrupoles, therefore two possible solutions of the final focus quadrupole are presented. The third part shows results and recommendations of the dynamic aperture and energy acceptance studies of one quarter of the whole ring.Speaker: Roman Martin (Humboldt-Universitaet zu Berlin (DE))

Muon detection and identification challengesThe design of the Muon Systems for FCC-hh poses interesting problems. Preliminary estimations of the background rate, and limits on the required time and space resolution, together with the necessary aging tolerance, are significantly more challenging that the ones foreseen for the experiments at HL-LHC. Given the requirements on the system that are presently known, it is difficult to think that one single detector technology can be successfully used everywhere in it. In this talk, the present technologies will be reviewed, trying to figure out which could be their possible evolution in the next twenty years, with a view to achieve those goals. Emphasis on the necessary synergies across R&D on different detector types will be put, and the relevant fields for a common effort outlined.Speaker: Marcello Abbrescia (INFN Bari)

Scaling behavior of circular collidersThe natural next future circular collider is an e+e- Higgs Factory and, after that, a post-LHC p,p collider in the same tunnel. For now the single most important parameter is the ring radius R, since all other parameters can be established later. Using only scaling laws to exptrapolate from existing colliders, this paper investigates ring circumferences two, or three, or four times greater than LEP's. The paper shows that "bigger is better", both for e+e- and (obviously) p,p. For a radiation dominated collider like the Higgs Factory, and arguably also for FCC-pp, the luminosity is shown to depend on R and the rf power P only through their product RP. This makes it possible for the same tunnel circumference to be optimal for both e+e- and p,p, without much increase in initial cost. For example, doubling R, compared to what might be marginally adequate for single Higgs production, and cutting P in half, say from 50 MW to 25 MW. The increase in start up cost associated with the increase in R is largely compensated by the decrease in cost associated with the reduction in P. This is especially true for yearly power costs. Other scaling laws are also derived, and their luminosity implications discussed.Speaker: Richard Talman (Cornell)

Industry response to the FCC specifications (Bruker)Magnets currently discussed for the FCC require Nb3Sn conductors in extremely large quantities as well as performance levels that have never been produced before. Bruker supplies Nb3Sn strand made by the Powder-In-Tube (PIT-) approach for HEP magnet applications. For FCC, specifically dedicated R&D will be required to satisfy the ambitious specifications which are currently in preparation. Bruker will give an outlook on how conductor R&D can improve performance from state of the art towards the desired objectives.Speaker: K. Schlenga (Bruker)
