Abstract

The TOTEM (TOTal cross section, Elastic scattering and diffractiondissociation Measurement at the LHC) experiment, located at theinteraction point 5 of the LHC, has measured the total, elastic andinelastic proton-proton cross-sections, using a luminosity independentmethod, based on the optical theorem, in a center-of-mass energy rangefrom 2.76 to 13 TeV. The elastic scattering was investigated in a widerange of the squared four-momentum transfer $|t|$ allowing studyof the Coulomb-nuclear interference region down to $|t| \sim 8\times10^{-4}$ GeV$^{2}$. This made possible the first measurement of the $\rho$parameter at $\sqrt{s} = 13$ TeV, $\rho$ being the ratio between the realand the imaginary part of the nuclear elastic scattering amplitude at$t = 0$. This measurement, combined with the total cross-sectionresults, led to the exclusion of all the models classified andpublished by the COMPETE Collaboration. The results obtained by TOTEMare indeed compatible with predictions of a colourless 3-gluon boundstate exchange in the t-channel of proton-proton elastic scattering,as postulated by alternative theoretical models both in the Regge-likeframework and in the modern QCD framework.In this contribution the TOTEM experiment detectors and results willbe described, along with the actual experiment status, the futurephysics program for the LHC Run~3.

Abstract

The Extreme-Energy Cosmic Rays (EECR), with energy above 5∙1019 eV, are very interesting objects to study that can provide new information about our universe. At the same time EECRs are exceptionally challenging to study because they are so rare. To obtain a reasonably large statistical sample, the JEM-EUSO collaboration aims to place a telescope into space. Various technologies are being developed and studied to achieve this goal. Several pathfinders are used for validation and testing. In particular, during 2017 a long-duration super-pressure balloon flight will observe the first high energy cosmic rays from above using the fluorescence technique, and a small test unit, Mini-EUSO, will be sent to ISS to measure the UV-background from Earth night side. In addition, these missions will provide various scientific results.

Abstract

The precise knowledge of the proton-proton cross section is extremely important to model the development, in the atmosphere, of the showers induced by the interaction of ultra high energy cosmic rays. The TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement at the LHC) experiment, located at the interaction point 5 of the LHC, has measured the total, elastic and inelastic proton-proton cross-sections, using a luminosity independent method, based on the optical theorem, in a center-of-mass energy range from 2.76 to 13 TeV. The elastic scattering was investigated in a wide range of the squared four-momentum transfer |t| allowing the study of Coulomb-nuclear interference region down to |t| ~8 x \(10^{-4} GeV^{2}\). This made possible the first measurement of the rho parameter at \(\sqrt{s} = 13 TeV\), rho being the ratio between the real and the imaginary part of the nuclear elastic scattering amplitude at t = 0. This measurement, combined with the total cross-section results, led to the exclusion of all the models classified and published by the COMPETE Collaboration. The results obtained by TOTEM are indeed compatible with predictions of a colorless 3-gluon bound state exchange in the t-channel of proton-proton elastic scattering, as postulated by alternative theoretical models both in the Regge-like framework and in the modern QCD framework. In this contribution the latest TOTEM will be given, along with the actual experiment status and the future physics program for the LHC run 3.

Abstract

New results on the galactic cosmic ray (GCR) short-term intensity variation associated with Forbush decrease and co-rotating interaction regions (CIRs) measured by the PAMELA instrument between November 2006 and March 2007 are presented. Most of the past measurements on Forbush decrease events were carried out with neutron monitor detector. This tecnique allows only indirect detection of the overall GCR intensity over an integrated energy range. For the first time, thanks to the unique features of the PAMELA magnetic spectrometer, the Forbush decrease associated with the December 13th coronal mass ejection (CME) was studied in a wide rigidity range (0.4-20 GV) and for different species of GCRs detected directly in space. Using GCR protons, the amplitude and the recovery time of the Forbush decrease were studied for ten rigidity interval with a temporal resolution of one day. For comparison the helium and the electron intensity over time were also studied. The temporal evolution of the helium and proton intensity was found in good agreement while the electrons show, on average, a faster recovery time. This was interpreted as a charge-sign dependence introduced by drift motion experienced by the low rigidity (

Abstract

EUSO-Balloon is a pathfinder mission for JEM-EUSO, the near-UV telescope proposed to be installed on board the ISS in 2017. The main objective of this pathfinder mission is to perform a full scale end-to-end test of all the key technologies and instrumentation of JEM-EUSO detectors and to prove the entire detection chain. EUSO-Balloon will measure the atmospheric and terrestrial UV background components, in different observational modes, fundamental for the development of the simulations. Through a series of flights performed by the French Space Agency CNES, EUSO-Balloon also has the potential to detect Extensive Air Showers (EAS) from above. EUSO-Balloon will be mounted in an unpressurized gondola of a stratospheric balloon. We will describe the instrument and the electronic system which performs instrument control and data management in such a critical environment. © 2013 Elsevier B.V.

Abstract

The LHC energy begins to overlap with the energy range where extreme energy cosmic-ray showers are studied. Investigations of proton-proton interactions at the LHC are therefore of high importance for the study of the development of cosmic-ray showers in the atmosphere and thus for the measurements of the high-energy cosmic-ray spectra and composition. The TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement at the LHC) experiment at LHC, has been designed to measure the total proton-proton cross-section with a luminosity independent method, based on the optical theorem, and study the elastic and diffractive scattering at the LHC energy. This method relies on the capability of the simultaneous measurements of inelastic and elastic rates; in the TOTEM experiment this is possible thanks to two forward inelastic telescopes, covering the pseudorapitidy range 3.1 < |h| < 6.5, and Roman Pot detectors, that can be inserted down to few hundred microns to the beam centre. Thanks to dedicated runs, taken between 2011 and 2012, with special beam optics, TOTEM experiment was able to measure the elastic, inelastic and total cross-section at ps = 7 TeV and 8 TeV, using the luminosity independent method, along with the pseudorapidity distribution of charged particles. In this contribution the latest results of the TOTEM experiment will be described along with its performance and the future physics program for the LHC run 2.

Abstract

For the JEM-EUSO Collaboration; The EUSO-Balloon is a pathfinder of the JEM-EUSO mission, designed to be installed on-board the International Space Station before the end of this decade. The EUSO-Balloon instrument, conceived as a scaleddown version of the main mission, is currently developed as a payload of a stratospheric balloon operated by CNES, and will, most likely, be launched during the CNES flight campaign in 2014. Several key elements of JEM-EUSO have been implemented in the EUSO-Balloon. The instrument consists of an UV telescope, made of three Fresnel lenses, designed to focus the signal of the UV tracks, generated by highly energetic cosmic rays propagating in the earth's atmosphere, onto a finely pixelized UV camera. In this contribution, we review the main stages of the signal processing of the EUSO-Balloon instrument: the photodetection, the analog electronics, the trigger stages, which select events while rejecting random background, the acquisition system performing data storage and the monitoring, which allows the instrument control during operation.

Abstract

The PAMELA satellite borne experiment is designed to study cosmic rays with great accuracy in a wide energy range. One of PAMELA's main goal is the study of the antimatter component of cosmic rays. The experiment, housed on board the Russian satellite Resurs-DK1, was launched on June 15th 2006 and it is still taking data. In this work we present the measurement of galactic positron energy spectrum in the energy range between 500 MeV and few hundred GeV., Comment: 4 pages, 4 figures, v2: MLP variable description added, bibliography updated. A revised version will appear in proc. 33rd International Cosmic Ray Conference, Rio de Janeiro 2013

Abstract

Imaging calorimeter of the PAMELA instrument on board the Resurs DK satellite has high spatial resolution and allows to measure separately electromagnetic showers from electrons and positrons and their bremsstahlung produced in ToF detectors of the instrument. Measuring events with two showers provides proton rejection coefficient more than 104 at energy between 0.5 and 3 GeV. Results of positrons fractions obtained by this method are in agreement with previously published data of the PAMELA experiment at low energy. It confirms in independent way strong positron modulation during period of negative polarity of the Sun magnetic field © 2013 Sociedade Brasileira de Fisica. All Rights Reserved.

Abstract

Data from the PAMELA satellite experiment were used to measure the geomagnetic cutoff for high-energy ( 80 MeV) protons during the solar particle events on 2006 December 13 and 14. The variations of the cutoff latitude as a function of rigidity were studied on relatively short timescales, corresponding to single spacecraft orbits (about 94 minutes). Estimated cutoff values were cross-checked with those obtained by means of a trajectory tracing approach based on dynamical empirical modeling of the Earth's magnetosphere. We find significant variations in the cutoff latitude, with a maximum suppression of about 6 deg for 80 MeV protons during the main phase of the storm. The observed reduction in the geomagnetic shielding and its temporal evolution were compared with the changes in the magnetosphere configuration, investigating the role of IMF, solar wind and geomagnetic (Kp, Dst and Sym-H indexes) variables and their correlation with PAMELA cutoff results.
