Description

Following the successful 2011 and 2012 meetings, we propose a new edition of LHC LumiDays, dedicated to luminosity and emittance measurements during Run 2. The goal is to review the progress, over the last 4 years, in the determination of the LHC luminosity, the measurement and understanding of  the emittance, and the modeling of the luminosity based on the measured or calculated evolution of single-beam parameters.

This workshop will focus on the Run-2 results and will be followed by another one in early to mid  2020 to discuss in detail the strategy for Run-3.

A list of useful references and documents of relevance for the workshop can be found here, as well as in the proceedings of the past workshop available from
http://cdsweb.cern.ch/record/1347440

Program organization:

Exp: F. Alessio, V. Balagura, J. Contreras-Nuno, A. Dabrowski, M. Gagliardi, R. Hawkings, W. Kozanecki, R. Matev, A. Polini, D. Stickland

Accel: H. Burkhardt, I. Efthymiopoulos, S. Fartoukh, R. Jones, T. Lefevre, Y. Papaphilippou, G. Sterbini, R. Tomas-Garcia, G. Trad, J. Wenninger

Proceedings
Speakers should write-up their contributions (1 paper per talk, no page limit but recommended length approx. 5 pages) by using the JACoW templates.
All papers (format ps and word or LATeX with images, no pdf files) are to be uploaded directly the indico timetable, with initial target 
date end of October 2019.
