2. TWEPP2013: Topical Workshop on Electronics for Particle Physics
23-27 September 2013, Perugia, IT The workshop will cover all aspects of electronics for particle physics experiments, and accelerator instrumentation of general interest to users. LHC experiments (and their operational experience) will remain a focus of the meeting but a strong emphasis on R&D for future experimentation will be maintained, such as SLHC, CLIC, ILC, neutrino facilities as well as other particle and astroparticle physics experiments. Contributions: 167 Posters, Oral presentations, Reviews, Articles…
