ML Track Fitting in Nuclear Physics

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...

Track 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...

A Track Physics Retrospective

Many condensed matter dosimeters and detectors respond to the perspectives of track physics, a parametric model which relates their response to gamma rays to their response to heavy ions through the radial distribution of dose about a heavy ion’s path. Most dosimeters are treated as 1-hit detectors, a classification which includes emulsions, scintillators, TLDs, the Fricke dosimeter, alanine, a...

Frontiers in Nuclear Physics

These are the proceedings of the symposium on “Frontiers in Nuclear Physics” held at the Physikzentrum Bad Honnef from June 18 to 20, 2009. The workshop concentrated on recent advances in the understanding of the nuclear forces, fewnucleon systems and related topics. Included are a short contribution per talk. ∗ This symposium was supported in parts by funds provided from the Helmholtz Associat...
