This is a critical restriction in the context of galactic cosmic rays, which have a power-law spectrum extending up to a relativistic factor of 1 million. If they are to produce particles with higher relativistic factors, the losses due to inverse Compton scattering of the electromagnetic radiation in them outweigh the acceleration, and this violates the assumptions of the theory. It is shown that any isotropic synchrotron or Compton reactors with reasonable astrophysical parameters can yield particles with a maximum relativistic factor of only about 10,000. The 'reactor' theories of Tsytovich and collaborators (1973) of cosmic-ray acceleration by electromagnetic radiation are examined in the context of galactic cosmic rays. We propose that U as a doubly magic nucleus by the RMF model is not affected by the inclusion of isoscalar-isovector and electromagnetic exchange couplings.ĭoes electromagnetic radiation accelerate galactic cosmic rays We investigate a possible new doubly magic heavy nucleus by using a relativistic mean-field (RMF) model with the addition of a cross interaction term of omega-rho mesons and an electromagnetic exchange term.

VMS, UNIX, and DOS versions are supported, with migration underway toward windows environments. Post-processors compute and display beam properties including geometric, normalized, and slice emittances, and phase-space parameters, and video. Interfaces have been added to receive electromagnetic field information from the Poisson group of codes and from EGUN and to send beam information to PARMELA for subsequent tracing of bunches through beam optics. The recent addition of an export/import feature now allows long devices to be modeled in sections. An axial filter in SOS accelerates simulations in cylindrical coordinates. Two new field algorithms allow improved control of computational numerical noise and selective control of harmonic modes in RF cavities.
Algorithmic improvements for PIC have been developed and added to MAGIC and SOS to facilitate these modeling efforts.
Examples include high brightness electron guns, beam-RF interactions in klystrons, cold-test modes in an RFQ and in RF sources, and a high-quality, flexible, electron gun with operating modes appropriate for gyrotrons, peniotrons, and other RF sources. MAGIC and SOS have been applied to investigate a variety of accelerator-related devices.
