Abstract:
A fast method of retracing orbits through a large, inhomogeneous magnetic field has been developed for applications in particle-physics experiments. The momenta of particles are found by simple linear interpolation in a mesh of previously calculated representative orbits. The essential feature of the scheme is to perform a transformation on the set of observables defining the orbit before doing the interpolation. This is done to reduce both interpolation errors and the required number of mesh points. A detailed development of the method is presented for an actual apparatus. For this apparatus particles were retraced in 0.6 msorbit using a CDC 6600 computer, and for 100 mesh points interpolation errors were found to be smaller than experimental errors by more than an order of magnitude.
