In these last years, there is an unprecedented world-wide consensus on the next steps to be taken in the construction of major “energy frontier” accelerator facilities. The main threads for the ...future of world particle physics seem clear: the first priority is the completion and commissioning of the large hadron collider (LHC), the next priority is the construction of the TeV-energy LC, with a significant period of overlap with LHC running.
If the “energy frontier” for the future activities in particle physics seems to be well defined, it is becoming more and more relevant and urgent to underline the importance of other facilities for particle physics. This Report focuses the importance of a diversified experimental program in flavour physics during the LHC era. In particular this Report presents the great opportunities, offered by flavour physics, on a number of fronts within the quark flavour sector, K and charm physics, as well as within neutral and charged-lepton sector, neutrino physics and physics of lepton flavour violation. Finally it is briefly illustrated how future high intensity facilities may also offer an opportunity to perform frontier experiment in nuclear physics.

A sample of ASIC prototypes of the first-level trigger front-end device for the muon barrel drift chambers of CMS was tested on a full size chamber prototype. Tests were performed at several incident ...angles on cosmic rays and at normal incidence using a muon beam. The chamber was irradiated using a

Three simplified prototypes of the first-level trigger front-end device for the muon barrel drift chambers of CMS were tested on a chamber prototype. Tests were performed at several incidence angles ...of a muon beam and with different magnetic field configurations.
The recorded drift times were also used to test a full software model reproducing the actual algorithm applied in the final ASIC being produced.
The efficiency performance of this software model and of the tested prototype are presented in this paper.
A lead scintillator sandwich sampling calorimeter has been installed in the HERA tunnel 105.6 m from the central ZEUS detector in the proton beam direction. It is designed to measure the energy and ...scattering angle of neutrons produced in charge exchange ep collisions. Before installation the calorimeter was tested and calibrated in the H6 beam at CERN where 120 GeV electrons, muons, pions and protons were made incident on the calorimeter. In addition, the spectrum of fast neutrons from charge exchange proton-lucite collisions was measured. The design and construction of the calorimeter is described, and the results of the CERN test reported. Special attention is paid to the measurement of shower position, shower width, and the separation of electromagnetic showers from hadronic showers. The overall energy scale as determined from the energy spectrum of charge exchange neutrons is compared to that obtained from direct beam hadrons.
The barrel muon chambers of the CMS detector consist of three sets of four layers of rectangular drift tubes. The performance of several prototypes was measured in a muon beam for various ...experimental conditions. Special emphasis was given to study performance aspects related to the trigger capability of the chambers.
