The purpose of this workshop is to bring together scientists with different backgrounds and expertise to discuss open problems, recent developments and future directions in axion physics, a field that is notoriously replete with interdisciplinary connections. The aim is to foster a fruitful cross breeding between different theoretical areas, with a focus on certain open issues in axion particle physics, astrophysics and cosmology. Quantitative assessments of the axion contribution to Cold Dark Matter (CDM) involve top-notch lattice simulations of non- perturbative QCD effects, as well as of the cosmic evolution of axionic topological defects. Astrophysical observations provide strong bounds on axion properties because stellar evolution would be affected by the existence of axions and, intriguingly, some excesses in star energy losses have been reported. Cosmological scenarios in which the PQ symmetry is broken before inflation foresee axions imprints in the CMB, while in post-inflationary scenarios axion miniclusters, with overdensities several orders of magnitude larger than the local density of CDM, are expected to form, and a reliable assessment of their properties is of utmost importance. From the experimental side, a blossoming of potentially game-changing ideas, with an exciting crossover from experimental particle physics to materials science and cutting-edge technologies is inspiring new methods for axion searches. Novel techniques have been put forth that, besides exploiting the axion- photon coupling, aim to reveal axions via their couplings to nucleons and electrons. The interaction between the experimental and theoretical communities will foster the merging of `how to search’ with `where to search’ into optimized strategies to hunt for the axion.

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 eighth of a series of conferences devoted to endorsing and promoting scientific and technical activities based on nuclear instrumentation and measurements.

Cosmic-ray muons, continuosly reaching the Earth soil with an almost constant and well known rate, are exploited as tool to probe the interior of large scale objects up to the kilometer scale. Muon radiography is reaching promising results in several applications where other thecniques are not suitable. The International workshop on muography is a conference series, intended as an opportunity to share the knowledge and the most recent progresses within the muon radiography community and other interested scientists.
