Three Approaches for Complete Measurement of the Transverse Beam Optics Along the Fermilab Muon Campus Extraction Line

Traditionally, the process of measuring the optical parameters of a beamline has employed the use of one of two standard methods, namely the three-screen method or a quadrupole magnet scan. Both require either an area of zero dispersion to perform the measurements or knowledge of the dispersion function and momentum spread beforehand in order to provide accurate results. There is however a third method that can be used to measure the standard optical parameters, the beam parameters, the dispersion function, and the momentum spread simultaneously. This method, aptly named the six-screen method, is an extension of the more standard three-screen method. Utilizing the simulation environment of G4beamline, we simulated the 8 GeV proton beam in the M4 beamline and measured the optical and beam parameters using the two standard approaches. Those results were then used as a reference to check the viability of employing the less standard six-screen method in the M4 line. If shown to be a viable option, the six-screen method could be used to retrieve the dispersion function and momentum spread of the beam without needing to change the energy of the beam.

Muon Collider Pulsed Synchrotron Parameters

I work out approximate parameters for an acceleration scenario from 63 GeV to 1500 GeV using pulsed synchrotrons. I used parameters arrived at for MAP design studies. I ignore straight lengths for quadrupoles and inter-magnet spacing. Acceleration from 63 GeV to 750 GeV will be accomplished using two machines in a common tunnel: a non-hybrid pulsed synchrotron from 63 GeV to an intermediate energy, followed by a hybrid pulsed synchrotron to 750 GeV. Acceleration to 1500 GeV will be accomplished with a hybrid pulsed synchrotron. All acceleration is accomplished with 1300 MHz RF.
