Power supply system for the TRIUMF KAON factory
The TRIUMF KAON factory consists of five rings, three of which are DC powered, and two synchrotrons running at 50 Hz and 10 Hz, respectively. The author deals with the power supply system envisaged for the accelerator as well as the experimental results obtained using DC-biased single- and dual-frequency resonant magnet excitation for the booster and driver synchrotrons. Test results show that due to the high Q of the circuits, a relatively small mismatch effectively doubles the current requirements from the power supply feeding the pulsed forming network. This implies that the nominal rating of the supply must be significantly higher than that required for optimum tune.<<ETX>>
A 50 Hz dipole magnet for the TRIUMF KAON factory booster ring
The 3-GeV booster synchrotron for TRIUMF's KAON Factory will need 24 dipole magnets each 3.0-m long operating with a resonant power system designed to give a 50-Hz AC field superimposed onto a DC field. The maximum and minimum field levels are 1.118 and 0.295 T, respectively. The magnet design is presented and compared with measured results from a prototype which was constructed to evaluate fabrication procedures and to verify the AC loss calculations. The experiences gained from this fabrication are described. The prototype magnet measured parameters were very close to the design values, giving confidence in the methods of calculation and fabrication techniques. The prototype also served as a test of the power supply and its components and highlighted some of the control aspects that must be incorporated for a working synchrotron ring. >
The unfolded universe of elementary particles. A geometric explanation of the standard model structure
We propose a geometric explanation of the standard model of Glashow, Weinberg and Salam for the known elementary particles. Our model is a generic Quantum Field Theory in dimension four, obtained by developing along a Lorentz sub-manifold the lagrangian of Einstein and Dirac in dimension twelve. The main mechanism which gives birth to the standard model is a certain gauge fixing of triality, which permits to identify the multiplicity of fermions, as seen from the four dimensional world, with the eight unseen dimensions of the generating universe. In this way we get the known tables of particles, explaining the series of fermions and the gauge bosons. We suggest that the Higgs field dynamics could appear through a bosonization of the right handed neutrino and correspond to a displacement in the unseen dimensions. We also propose hypotheses for dark matter, and perhaps dark energy. Then we suggest predictions to go beyond the standard model.
