Hardware Tracking Related to Compact Medical Pulse Synchrotron

A compact 200 MeV proton synchrotron for the radiotherapy is being developed. Dipole and quadrupole magnets were already manufactured and their field measurement is now going on under the pulse excitation. Preliminary field measurement was already done on the prototype dipole. Small RF cavity with a wide bandwidth (2∼ 18 MHz) was successfully developed. Concerning to the simultaneous pulse operation of these components, there are some issues to be solved beforehand. These are the tracking between dipole field and the quadruple field gradient and the RF frequency generation sensing the dipole current (or field). These problems are being studied experimentally and numerically referring to the dipole current which plays an important role in the simultaneous operations of the synchrotron components.
