The instantaneous luminosity of the Large Hadron Collider at CERN will be increased up to a factor five with respect present design value by undergoing an extensive upgrade program over coming decade. most important project for ATLAS Muon System is replacement first station in forward regions so-called New Small Wheels (NSWs). NSWs installed during LHC long shutdown 2018/19. Small-Strip Thin Gap Chamber (sTGC) detectors are designed provide fast trigger and high precision muon tracking under...
For the Phase-II Upgrade of ATLAS Detector [1], its Inner Detector, consisting silicon pixel, strip and transition radiation sub-detectors, will be replaced with an all new 100% tracker, composed a pixel tracker at inner radii outer radii. The future include 11,000 sensor modules in central region (barrel) 7,000 forward (end-caps), which are foreseen to constructed over period 3.5 years. construction each module consists series assembly quality control steps, were engineered identical for...
The smuggling of illicit Special Nuclear Materials (SNM) and Radiological (RM) is a major security concern. Current radiation detection systems for cargo are not sensitive to well-shielded nuclear materials. Muon Scattering Tomography (MST) method that we developing might be solution this problem. It based on the measurement multiple scattering cosmic ray-induced muons, traversing high-Z materials such as uranium plutonium. This possible due muons' highly penetrating nature. technique...
In the last decade, many groups around world have been exploring different ways to probe transport containers which may contain illicit Special Nuclear Materials such as uranium. The muon tomography technique has proposed a cost effective system with an acceptable accuracy. A group of Canadian institutions (see above), funded by Defence Research and Development Canada, is testing technologies track cosmic muons. One candidate single wire Drift Chamber. With capability 2D impact position...
The CRIPT Cosmic Ray Imaging and Passive Tomography system began data taking in September 2012. is a “proof of principle” muon tomography originally proposed to inspect cargo shipping containers determine the presence special nuclear materials. uses 4 layers 2 m x scintillation counter trackers, each layer measuring two coordinates. Two are used track incoming for outgoing allowing trajectories be determined. target volume divided into voxels, Point Closest Approach algorithm number...
The Cosmic Ray Inspection and Passive Tomography (CRIPT) collaboration has completed the testing of small muon detector prototypes commenced construction a 12 layer, 4m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> prototype scattering tomography system. Three areas CRIPT's progress are reported: (1) results from one drift chamber prototypes; (2) algorithms for momentum estimation tomographic image reconstruction; (3) status large...
Muons, which are produced naturally in the upper atmosphere, can be used to scan cargo for special nuclear materials (SNM). Preliminary simulated results show that detecting presence of these accomplished by measuring scattering cosmic ray muons. Machine learning tools have been on data classify it as SNM or not. The muon exists long enough, and is penetrating passively detect SNM. By deflection angles muons after they exit a container, one determine whether not present. Different detector...
The Cosmic Ray Inspection and Passive Tomography (CRIPT) project is investigating muon scattering tomography (MST) for applications in border security, nuclear non-proliferation, waste characterization. construction of the full-scale prototype MST system began Summer 2011 was completed September 2012. CRIPT detector employs 12 layers scintillator to track atmospheric muons before after passage through a volume interest, estimate each muon's momentum. total height 5.5 m its weight 20 tonnes....
The CRIPT project brings together several Canadian institutions, concerned with the detection of Special Nuclear Materials (SNM), addressing a requirement at ports-of-entry for SNM in many thousands containers that flow into and out Canada every day, while same time providing way monitoring contents nuclear waste storage containers, management non-proliferation reasons. scale these applications is large - typically tens cubic metres, requiring detectors can cover area minimum cost....
