Ranging from low-energy factories like DAFNE and BEPC, to record-luminosity machines such as Super KEKB, and the proposed high-energy future circular electron positron colliders CEPC/FCC-ee, lepton colliders have been for a long time the most widely used collider species, found all around the world.
Recently, the commissioning of Super KEKB has started, BEPC-II achieved its design luminosity, CEPC and FCC-ee have made great strides forward approaching a complete design, while accelerator-design breakthroughs combined with physics prospects have sparked a renewed interest in super tau-charm factories.
Many design challenges of e+e- colliders are shared with the ever more ambitious plans for storage ring light sources. ICFA is encouraging the global coordination of, and joint research on, factory-like circular colliders. The eeFACT2016 workshop held in Daresbury, UK, from 24 to 27 October 2016, will cover the full scope of circular lepton colliders over a wide range of energies, and address complementary physics. Topical working groups including contributions from the light-source community are foreseen.
eeFACT2016 will address all aspects of present and future e+e- factories, through plenary talks and 13 dedicated working groups covering physics landscape and motivations, design concepts, optics issues, interaction region and machine detector interface, beam-beam issues, injectors and beam injection, impedance issues and beam instabilities, emittance control, polarization, beam instrumentation and beam diagnostics, superconducting RF, other technologies, and energy efficiency.
The goals of the eeFACT16 workshop are:
Reviewing and documenting the state of the art in e-e+factory design.
Preparing plans for the commissioning of SuperKEKB and advancing contributions to the FCC,CEPC & tau-charm design efforts.
Fostering synergies and new collaborations across communities, in particular with the low-emittance light sources.
Jointly developing novel solutions to outstanding problems.

Enter the title of the abstract, using initial capital letters only,
The default for all contributions is talk.
To complete submission of an abstract, authors are required to select a classification. Invited Plenary and Summary Speakers have been assigned a separate classification. All other classifications are based on the program tracks for the Workshop. Authors are responsible for properly classifying their abstracts to ensure that, if accepted for presentation, their papers are properly placed within the conference program.
Abstract text should not exceed 1200 characters. An abstract is a concise summary of a paper. It should describe the paper and include a statement of the issue, research methods, and significant findings. Abstracts should be written as one continuous paragraph. Since electronic submission over the web does not allow a simple, straightforward system to enter symbols, superscripts or subscripts, authors are requested not to use them. Also, equations and footnotes are not acceptable within the body of abstracts and will be removed by the proceedings editor. Use one or more asterisks (*, **, etc.) to indicate footnotes to be entered in the footnotes field (see below).
Footnotes not exceeding 200 characters may be inserted in the footnote field for references to co-authors, institutions, etc.
References to funding agencies may also be included and should not exceed 200 characters.
Once the abstract text is entered, click the "Submit" button. Confirmation of submission will be sent by email.
The next immediate step is to enter information regarding co-authors.
