In response to the 2013 Update of European Strategy for Particle Physics, Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This covers a highest-luminosity high-energy lepton collider (FCC-ee) and energy-frontier hadron (FCC-hh), which could, successively, be installed in same 100 km tunnel. The scientific capabilities integrated FCC programme would serve worldwide community throughout 21st century. also investigates LHC energy upgrade,...

A new Micromegas manufacturing technique, based on kapton etching technology, has been developed recently, resulting in further improvement of the characteristics detector, such as uniformity and stability. Excellent energy resolution obtained, reaching 11% FWHM for 5.9 keV photon peak the55Fe X-ray source 1.8% (with possible evidence less than 1%) 5.5 MeV alpha 241Am source. The Microbulk detector shows several advantages like flexible structure, low material high radio-purity, opening thus...
We review the physics potential of a next generation search for solar axions: International Axion Observatory (IAXO) . Endowed with sensitivity to discover axion-like particles (ALPs) coupling photons as small gaγ∼ 10−12 GeV−1, or electrons gae∼10−13, IAXO has find QCD axion in 1 meV∼1 eV mass range where it solves strong CP problem, can account cold dark matter Universe and be responsible anomalous cooling observed number stellar systems. At same time, will have enough detect lower axions...
A bstract This article describes BabyIAXO, an intermediate experimental stage of the International Axion Observatory (IAXO), proposed to be sited at DESY. IAXO is a large-scale axion helioscope that will look for axions and axion-like particles (ALPs), produced in Sun, with unprecedented sensitivity. BabyIAXO conceived test all subsystems (magnet, optics detectors) relevant scale final system thus serve as prototype IAXO, but same time fully-fledged physics reach itself, potential discovery....
The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in 2030s. ILC addresses key questions for our current understanding of particle physics. It based proven technology. Its experiments will challenge Standard Model physics and provide window to look beyond it. This document brings story up date, emphasizing its strong motivation, readiness construction, opportunity it presents US community.
Khufu's Pyramid is one of the largest archaeological monument all over world, which still holds many mysteries. In 2016 and 2017, ScanPyramids team reported on several discoveries previously unknown voids by cosmic-ray muon radiography that a non-destructive technique ideal for investigation large-scale structures. Among these discoveries, corridor-shaped structure has been observed behind so-called Chevron zone North face, with length at least 5 meters. A dedicated study this was thus...
Muon tomography is a consolidated technique to investigate the internal components of high-opacity objects. With use detectors with high angular and spatial resolution (usually referred as “muon telescopes”), track reconstruction atmospheric muons after they have crossed object provides muography images, also called radiographs.” This work presents (or muon radiography) French historical UNGG (natural-uranium, graphite, gas) nuclear reactor: G3 reactor, located at CEA Marcoule. A measurement...
In this document, we present the Technical Design Report of Upgrade T2K Near Detector ND280. The goal upgrade is to improve performance measure neutrino interaction rate and constrain cross-sections so that uncertainty in number predicted events at Super-Kamiokande reduced about 4%. This will allow physics reach T2K-II project. achieved by modifying upstream part detector, adding a new highly granular scintillator detector (Super-FGD), two TPCs (High-Angle TPC) six TOF planes.

The inspection of very large or thick structures represents one the biggest challenges for nondestructive techniques. For such objects, a particularly powerful technique is muography, which makes use free, natural cosmic-ray muons. Among other applications, this has been applied to provide two-dimensional (2D) images nuclear reactors, pyramids, volcanos. Recently, 3D algorithms developed medical applications were adapted special case muon imaging derive density maps. main difficulties relate...
On Oct. 17, 2002, the ESA INTEGRAL observatory was launched into a highly elliptical orbit. SPI, high resolution Ge spectrometer covering an energy range of 20–8000 keV, is one its two main instruments. We use data recorded early in mission (i.e. March 2003) to characterize instrumental background, particular many gamma-ray lines produced by cosmic-ray interactions instrument and spacecraft materials. More than 300 spectral features are observed, for about 220 which we provide...
Three calibration campaigns of the spectrometer SPI have been performed before launch in order to determine instrument characteristics, such as effective detection area, spectral resolution and angular resolution. Absolute determination area has obtained from simulations measurements. At 1 MeV, is 65 cm^2 for a point source on optical axis, ~2.3 keV. The better than 2.5 deg separation capability about deg. Some temperature dependant parameters will require permanent in-flight calibration.
In this paper we discuss the methods developed for production of INTEGRAL/SPI instrument response. The response files were produced using a suite Monte Carlo simulation software at NASA/GSFC based on GEANT-3 package available from CERN. also required development detailed computer mass model SPI. We our extensive investigations into to reduce both computation time and storage requirements SPI corrections simulated comparison ground inflight calibration data with MGEANT simulations.
