ALPS II is a light shining through a wall style experiment that will use optical cavities to resonantly enhance the coupling between photons and axion-like particles in the mass range below 0.1 meV. In the last year there has been significant experimental progress in the development of the optical system and the single photon detection schemes, as well as progress related to the preparation of the magnets and the on site infrastructure.

We present the project to install new forward proton detectors in the CMS and ATLAS experiments called PPS and AFP respectively.

Radiation damage effects represent one of the limits for technologies to be used in harsh radiation environments as space, radiotherapy treatment, high-energy phisics colliders. Different technologies have known tolerances to different radiation fields and should be taken into account to avoid unexpected failures which may lead to unrecoverable damages to scientific missions or patient health.

The purpose of the paper is the development of the formalism for the treatment of rare events especially, when one applies active correlation method to suppress background products in the heavy ion induced complete fusion nuclear reactions. This formalism in fact is an extension of classical background signal combinations formalism for the case of time multi intervals.

In this paper we model by using the Monte Carlo simulation code PENELOPE [1, 2] a Broad Energy Germanium (BEGe) detector and determine its efficiency. The simulated geometry consists of a point source located close to the detector as well as volume sources with cylindrical geometry. A comparison of the simulation is made to experimental results as well as to analytical calculations.

This article is a short summary of the talk presented at 2014 Instrumentation Conference in Novosibirsk about Fermilab's experimental program and future plans. It includes brief description of the P5 long term planning progressing in US as well as discussion of the future accelerators considered at Fermilab.

A simple model is explored mainly analytically to calculate and understand the PHS of single and multi-layer thermal neutron detectors and to help optimize the design in different circumstances. Several theorems are deduced that can help guide the design.

We used the Geant4 simulation toolkit to estimate the light collection in a LYSO crystal by using cosmic muons and E=105 MeV electrons. The light output as a function of the crystal length is studied. Significant influence of the crystal wrapping in the reflective paper and optical grease coupling to the photodetectors on the light output is demonstrated.

The CALICE Collaboration

We present an overview of the CALICE activities on calorimeter development for a future linear collider. We report on test beam analysis results, the status of prototype development and future plans.

We report on the development of an GRPCs (Glass Resistive Plate chambers) Semi- Digital hadron calorimeter for the future International Linear Collider (ILC).Two types of GRPCs (small and 1m2) were tested in PS beam at CERN. Detector performances are presented here in terms of efficiency, pad multiplicity, homogeneity and stability in time.

Despite an already long and fruitful history, gaseous elementary-particle detectors remain today an important mainstay of high-energy and nuclear physics experiments and of radiation detection in general. In here we briefly describe some of the gaseous detector's main technologies and applications, along with some unsolved gas-discharge physics aspects of practical relevance.

Simulated calorimeter performance in the SiD detector is examined. The software calibration procedures are described, as well as the perfect pattern recognition PFA reconstruction. Performance of the SiD calorimeters is summarized with jet energy resolutions from calorimetry only, perfect pattern recognition and the SiD PFA algorithm. Presented at LCWS08[1].

The parametric formulas are obtained whereby the refractive index and the light group velocity could be calculated for any water state (salinity, pressure, temperature) inside of the light wavelength region from 200 nm to 1200 nm. These formulas are suitable to be used in underwater neutrino telescope activity.

We study the thermal-noise spectrum of multi-loop pendulum suspensions for test masses in interferometric gravitational-wave detectors. The dependence of the thermal noise on suspension parameters and on properties of the wire material is discussed for the situation in which the losses are dominated by the internal friction in the pendulum wires.

We report on a technique developed to diagnostic for non working readout channels of the Transition Radiation Tracker (TRT), one of the three inner detectors of the ATLAS experiment. From a detailled study, we show that 99.6 % of the readout channels of the TRT endcap-detector are perfectly operational.

A. Andronic

We present the electron/pion identification performance measured with prototypes for ALICE TRD. Measured spectra of energy deposit of pions and electrons as well as their average values are presented and compared to calculations. Various radiators are investigated over the momentum range of 1 to 6 GeV/c. The time signature of TR is exploited in a bidimensional likelihood mothod.

The results of tests of more than 2200 ETL9351 type PMTs for the Borexino detector with the PMT test facility are presented. The PMTs characteristics relevant for the proper detector operation and modeling are discussed in detail.

A Time to Digital Converter was designed (CMOS 0.35 $\mum) in order to be used in Liquid Xenon PET prototype. The circuit proved to be able to work at -120 degrees C, while showing a resolution of 250 ps. The circuit enables a low readout dead time (<90 ns) and provides a fully synchronous digital interface for easy data retrieval.
