“…This Magnetic Angle Changing (MAC) device has now successfully been used in elastic and inelastic angular cross section studies from a number of different targets [21][22][23][24][25] and has also been used in (e,2e) ionization studies in a coplanar asymmetric geometry [26][27][28].…”

Super-elastic scattering processes can be considered as the 'time reversal' of electron-photon coincidence measurements, with the advantage that data are accumulated thousands of times faster. This allows a far more extensive and accurate study of electron excitation of atoms which can also be excited using laser radiation. The application of a newly invented magnetic angle changing (MAC) device to these experiments has allowed the complete scattering geometry to be accessed for the first time, and experimental methods adopted in these new experiments are discussed here. Data are presented for excitation of the 4 1 P 1 state of calcium by electron impact at scattering angles from near 0 • to beyond 180 • , with incident energies of 45 eV and 55 eV. The results are compared to the DWBA theory of Stauffer and colleagues, with generally excellent agreement.

“…One solution to this problem, developed by Cubric et al [5], is to incorporate a softiron core within the solenoids of the MAC. This significantly increases the magnetic field in the device, and hence greatly extends the range of electron energies that can be used.…”

The measurements of the angular distributions of charged particles have a long history in atomic and molecular collision studies. To detect all electrons originating from collision has great importance in experimental studies. Due to the physical constraints of the experimental instruments, electrons in definite angles can be detected. Magnetic angle changer is designed to steer electrons scattered at undetectable angles. The magnetic angle changer is a source of the localized magnetic field. A well-controlled magnetic field in the interaction region changes the angles of the electron trajectories. In this study, artificial neural networks have been performed to obtain variation of the magnetic field strength as a function of radial distance calculated from boundary element method. A stringent quality filter is used for data to produce more robust artificial neural network based prediction. The results indicate that the well-trained artificial neural networks can predict the effect on the radial dependence of the localized magnetic field with tremendous precision. It is believed that this study will introduce a new insight into collision studies.
