Low Emittance Rings 2014 Workshop

17 Sept 2014, 08:00 → 19 Sept 2014, 19:00 Europe/Rome

Aula B. Touschek, Bldg 36 (INFN-LNF)

The 4th Low Emittance Rings Workshop (LOWεRING 2014) will be held in Frascati, INFN-LNF on 17-19 September 2014, supported by the EuCARD-2 project.

The goal of the workshop is to bring together experts from the scientific communities working on low emittance lepton rings. This community, represented in the LOWεRING network and the Ultimate Storage Ring workshops collaboration, includes light source storage rings, linear collider damping rings and future e+/e‐ circular collider projects.

The workshop is the fourth in a series of workshops initiated in 2010:
LER2010
LER2011
LER2013

The theme will be beam dynamics and technology challenges for producing and controlling ultra‐low emittance beams and the participants will benefit from the experience of colleagues who have designed, commissioned and operated such rings.

Workshop sessions will include:
‐ Low Emittance optics design and tuning (LERD)
- Collective Effects and beam instabilities (IICE)
- Low Emittance Ring Technology (LERT)

Students are encouraged to participate and present posters. A prize will be awarded to the best student poster for participation in a major conference presenting work related to Low Emittance Rings.

Proposals for contributions to the workshop should be addressed to:

Riccardo Bartolini, riccardo.bartolini@diamond.ac.uk, JAI and Diamond Light Source
Yannis Papaphilippou, ioannis.papaphilippou@cern.ch, CERN
Susanna Guiducci, susanna.guiducci@lnf.infn.it, INFN-LNF

Participants in the Workshop are invited to register via web using the online registration form.

REGISTRATION DEADLINE: 20 July 2014
HOTEL ACCOMMODATION DEADLINE: 31 May 2014

EuCARD-2 is co-funded by the partners and the European Commission under Capacities 7th Framework Programme, Grant Agreement 312453.
