Track Fitting and Antennas
The problem of tting track data is transformed into a problem in antenna theory. This latter well-studied problem is characterized as an antenna array that is receiving a narrow band signal from multiple distant sources. The goal here is to count the number of sources and determine the angle of each source relative to the array. Similarly, the original problem of track tting is to count the num...
متن کاملTrack fitting in slightly inhomogeneous magnetic fields
A fitting method to reconstruct the momentum and direction of charged particles in slightly inhomogeneous magnetic fields is presented in detail. For magnetic fields of the order of 1 T and inhomogeneity gradients as large as 1 T/m the typical momentum bias due to the proposed approximations is of the order of few MeV, to be compared with scattering components of the order of 20 MeV or even lar...
متن کاملCovariance Matrices for Track Fitting with the Kalman Filter
We present a simple and intuitive derivation of the track parameter covariance matrix due to multiple Coulomb scattering for use in track fitting with the Kalman filter. We derive all the covariance matrix elements for two experimentally relevant track parameterizations (i.e. x and y slopes and intercepts, and direction cosines and intercepts) in the presence of thin scatterers and absence of m...
متن کاملThe Kalman Filter Technique Applied to Track Fitting in Glast
Using the iterative property of the Kalman Filter technique an estimate of the track parameter resolution for the case of the GLAST design (straight line tracks and periodic hits measurements) has been computed at the vertex position.
متن کاملError propagation of the track model and track fitting strategy for the Iron CALorimeter detector in India-based neutrino observatory
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...
