The 11th workshop on picosecond timing detectors, electronics and applications will take place in Torino, Italy, on May 16-18 2018, at the University of Torino, Italy. It will start on May 16 after lunch and will finish on May 18 in the evening. It will take place in the conference hall at the University. This workshop will address particularly the latest developments on Ultra Fast timing from 1-50 picosecond levels becoming achievable with the new technological development around recent photodetectors like solid state photodetectors (SiPM) and Multichannel Plates Photodetectors devices (MCP) but also new development with gaseous detectors like RPC and MGPD However, there are many challenging issues at many levels. The aim of this international workshop is to review the status of the various research and development aspects in a convivial and open-minded way with experts of these various developments and discuss the possible applications in a multidisciplinary environment from fundamental Physics (LHC and Super LHC, B factories, neutrino experiments, ILC and beyond) to medical applications on PET and particle therapy. The philosophy of this workshop follows the ones organized in Saclay (2007), Chicago (2005, 2006, 2008 and 2011), Clermont Ferrand (2009), Cracow (2010), Clermont-Ferrand (2014), Prague (2015), and Kansas City (2016).
