Several new experimental concepts in high-energy particle physics have been proposed recent years. The physical goals include precisely measuring the properties of particles such as Higgs, Z and W, even looking for signs at future colliders. To meet evolving requirements track detector, Time Projection Chamber (TPC) detector prototype integrated with a UV laser system was developed main Circula...

The Silicon Tracking System (STS) is the central detector of the CBM experiment. It serves for track reconstruction with good momentum measurement (of about of 1%) of all charged particles produced in high multiplicity nuclear reactions at the target [1]. For this task a lowmass silicon tracking detector system of high granularity is needed. We are currently studying the arrangement of the trac...

This report outlines the analytical procedures for bounding the performance of the ACF track functions. The open-loop bearing, time-delay, and frequency interpolation algorithms are rigorously analyzed by developing a probabilistic description for the coarse estimation errors as a function of the input signal-to-noise ratio and the interpolation parameters for both an energy detector (full-aper...

Background: Separate radon and thoron measurements in soil are very important in assessment of internal exposure due to inhalation of such radioactive gases. Materials and Methods: In this study, a low cost, small size, passive diffusion chamber has been developed for simple measurement of Radon-222 and Radon-220(Thoron) gases separately in soil. The diffusion chamber consists of two films and ...

In a detection&#10 network, the final decision is made by fusing the decisions from local detectors. The objective of that decision is to minimize the final error probability. To implement and optimal fusion rule, the performance of each detector, i.e. its probability of false alarm and its probability of missed detection as well as the a priori probabilities of the hypotheses, must be known. H...

The LHCb experiment is primarily dedicated to the study of new physics through the heavy flavour decays. The tracking system of LHCb is composed of a silicon micro-strip vertex detector, two silicon strip tracker detectors and a set of straw-tube drift chambers in front of and behind a dipole generating a magnetic field. This system provides precise measure of the vertex position and high momen...

Seasonal Variations in Muon Rate are caused by large scale changes in atmospheric conditions throughout the year. As atmospheric temperature and density vary across the seasons, so do the absorption rates of cosmic ray secondaries in the atmosphere. The IceCube neutrino detector array can track both large and small scale variations in atmospheric muon rate and daily, detailed weather data is av...

A Kalman filter package has been developed for reconstructing muon (μ) tracks (coming from the neutrino interactions) in ICAL detector. Here, we describe the algorithm of muon track fitting, with emphasis on the error propagation of the elements of Kalman state vector along the muon trajectory through dense materials and inhomogeneous magnetic field. The higher order correction terms are includ...

We present an interim report on Chandra HRC-S calibration observations of Vega, an Xray–dark and UV-bright star. The purpose of the observations is to monitor the UV response of the detector, and recently it has acquired further importance as a means to track the effects of increased radiation dosage on the UV/ion-shield of the detector. We find no conclusive evidence that leaving the HRC door ...

The alignment uncertainties of the CMS Tracker detector, made of a huge amount of independent silicon sensors with an excellent position resolution, affect the performances of the track reconstruction, the track parameters measurement and the vertex reconstruction. In order to study the impact of the mis-alignment of the CMS tracking devices on the previous procedures, realistic estimates for t...
