Physics with the KLOE-2 experiment at the upgraded DAϕ\phiNE

Investigation at a $\phi$--factory can shed light on several debated issues in particle physics. We discuss: i) recent theoretical development and experimental progress in kaon physics relevant for the Standard Model tests in the flavor sector, ii) the sensitivity we can reach in probing CPT and Quantum Mechanics from time evolution of entangled kaon states, iii) the interest for improving on the present measurements of non-leptonic and radiative decays of kaons and eta/eta$^\prime$ mesons, iv) the contribution to understand the nature of light scalar mesons, and v) the opportunity to search for narrow di-lepton resonances suggested by recent models proposing a hidden dark-matter sector. We also report on the $e^+ e^-$ physics in the continuum with the measurements of (multi)hadronic cross sections and the study of gamma gamma processes.Comment: 60 pages, 41 figures; added affiliation for one of the authors; added reference to section

Elemental Spectra from the CREAM-I flight

The Cosmic Ray Energetics And Mass (CREAM) instrument is a balloon-borne experiment designed to measure the composition and energy spectra of cosmic rays of charge Z = 1 to 26 up to an energy of ~ 10^15 eV. CREAM had two successful flights on long-duration balloons (LDB) launched from McMurdo Station, Antarctica, in December 2004 (CREAM-I) and December 2005. CREAM-I achieves a substantial measurement redundancy by employing multiple detector systems, namely a Timing Charge Detector and a Silicon Charge Detector (SCD) for particle identification, and a Transition Radiation Detector and a sampling tungsten/scintillating-fiber ionization calorimeter (CAL) for energy measurement. In this paper, spectra of various elements measured with SCD/CAL during the first 42-day flight are presented, along with spectral shapes and relative abundances

H and He spectra from the 2004/05 CREAM-I flight

The balloon-borne Cosmic Ray Energetics And Mass (CREAM) payload flew for a record-breaking 42 days during the 2004/05 Antarctic season. The instrument incorporates a tungsten/scintillating-fiber sampling calorimeter and graphite targets to measure energies of nuclei. A finely segmented Silicon Charge detector (SCD) located above the targets is used for charge measurements. The position of the primary particle in the SCD is determined by backward extrapolation of the reconstructed shower axis in the calorimeter. The flight data have been analyzed using the latest calibration of the calorimeter. The energy spectra of proton, helium and their ratios will be presented in this paper

However, in the presence of a calorimeter, the standard method of pulse charge integration over a time longer than a PMT pulse is hampered by abundant albedo particles. The Cosmic Ray Energetics and Mass (CREAM) instrument surmounts this problem by measuring the peak voltage of the PMT pulse within ~3ns of a threshold crossing in the readout of a timing charge detector (TCD). The design and performance of the TCD is presented. A charge resolution of 0.2e for oxygen and 0.4e for iron is obtained for through-going cosmic-ray particles

Healthy Universities: taking the University of Greenwich Healthy Universities Initiative forward

This paper aims to use and expand on the important work of the Healthy Universities' approach within higher education and the role the University can have in promoting health and well-being among staff, students and the local community. It focuses upon what we perceive to be important policy and practice developments to take forward the University of Greenwich Healthy Universities' pilot initiative (part of the national strategy). It sets out the background to the national Healthy Universities' strategy within the settings-based approach and briefly outlines the University of Greenwich Healthy Universities' pilot initiative; it then proceeds to outline three distinct but connected social and policy contexts that can be argued for to take forward and embed the initiative within the University. First, we focus on developments in current government policy, which emphasise the need to include concepts of health and well-being throughout policy and practice as a strategic and outcome tool. Second, we locate the initiative within ideas around community action and engagement, emphasising the need for it to be embedded locally; and third, we locate the local initiative within the wider setting of global and technological changes to strengthen the case for continued development

Timing charge and position analysis from the first CREAM flight

The first flight of the Cosmic Ray Energetics And Mass (CREAM) balloon experiment employed a Timing Charge Detector (TCD) and a Calorimeter. For high energy events a large background of back splash particles are created in the Calorimeter, which wash out the low Z charge peaks in the TCD. Traditionally, highly pixelated detectors are used in this situation in order to reduce the effects of the background. However, CREAM employed ultra fast photomultipliers and electronics in order to measure the rise time of the charge peak, which should be proportional to the amplitude of the charge peak and provide the charge of low Z cosmic rays when the peak detectors are saturated. These fast detectors also provide useful lateral tracking information along the direction of the scintillation paddle. These analysis techniques will be presented

GEANT4-Based Model of the CREAM Timing Charge Scintillation Detector

The CREAM instrument is a balloon-borne detector designed to measure the cosmic-ray spectrum in the 1-1000TeV energy range, with good charge resolution from protons to iron (Z = 1 to 26). The CREAM instrument has had two successful flights, both from McMurdo Station, Antarctica. CREAM-I was flown in the 2004-2005 Antarctic summer campaign and CREAM-II in 2005-2006, with a combined flight duration of approximately 70 days. The CREAM-I instrument consisted of a fast scintillation-based Timing Charge Detector (TCD), a Transition Radiation Detector and a sampling calorimeter. Here we describe a GEANT4-based model for a CREAM TCD scintillation counter, used in characterizing the charge and timing response of the counters to various incident particles. The model incorporates all counter components, including the scintillator, light guides and an approximation of the PMT readout. We compare the simulated output results to actual event signals
