Learning Objectives

  • Apply key concepts in E&M and basic analog circuits, introduced earlier in the electrical engineering curricula.
  • Analyze, design and optimize using theory presented in class. Use computer-aided design tools such as SIMION, Maxwell, HFSS, circuit simulators, Autodesk, Solidworks to confirm basic analytical predictions.
  • Understand how accelerator physics influences the design of various subsystems in a cyclotron.
  • After selecting an appropriate design problem, partition and distribute design tasks within each team.
  • Student groups will communicate to the class both mid-semester preliminary design problems as well as final projects results.
