Borexino, a liquid scintillator detector at LNGS, is designed for the detection of neutrinos and antineutrinos from the Sun, supernovae, nuclear reactors, and the Earth. The feeble nature of these signals requires a strong suppression of backgrounds below a few MeV. Very low intrinsic radiogenic contamination of all detector components needs to be accompanied by the efficient identification of ...

A description, results and the current status of the track-finding routines developed for the Transition Radiation Detector (TRD) of the CBM experiment are presented. The trackfinding algorithm is based on the Kalman Filter and track following methods. Two different approaches have been used: a standalone TRD track-finder (using only TRD information) and an algorithm based on the information fr...

The HERA–B experiment at DESY has acquired a data-set of approximately 300,000 decays J/ψ→ l+l− during its 2002/2003 data-taking period. These data are used to analyze the production of heavy quarks in proton-nucleus interactions at a center-of-mass energy of 41.6 GeV. In this article, preliminary results of two measurements are discussed, a measurement of nuclear effects in the production of J...

Development of novel approaches linking the physical characteristics of particles with biological responses are of high relevance for the field of particle therapy. In radiobiology, the clonogenic survival of cells is considered the gold standard assay for the assessment of cellular sensitivity to ionizing radiation. Toward further development of next generation biodosimeters in particle therap...

We have studied the impact of charged track resolution on Higgs mass and production cross section measurement in the process ee → ZH,Z → ll,H → X for Higgs masses between 120 and 160 GeV, and on smuon mass measurement using smuon pair production for three different mass pairs, assuming the International Linear Collider(ILC) is operated at 500 GeV center of mass energies (CME) with integrated lu...

The successful application of the TRD tracking algorithms [1] lead to the idea to generalize and optimize those algorithms in a flexible way in order to make them applicable for other, similar detectors. In this contribution we present how this idea was realized and applied for the TRD layout optimization and for track finding in the MuCh detector. Since both tracking detector setups (TRD and M...

The effect of annealing on track density in unirradiated CR-39 and gamma irradiated CR-39 neutron detectors was investigated. One group of CR-39 detectors (25.4 x 12.7 x 0.635 mm) was irradiated with 1.3 kGy of 6oCo gamma rays. The other group of detectors was not irradiated with gamma radiation. The two sets of detectors were then annealed at temperatures ranging from room temperature (2OOC) t...

This paper describes a new method for momentum reconstruction of charged particles using multiple Coulomb scatterings in nuclear emulsion detector with layered structure films and target materials. The utilizes the scattering angles precisely measured films. is based on maximum likelihood to newly include information decrease energy as particle travels through detector. According Monte Carlo si...
