The rapid cycling synchrotron of the intense pulsed neutron source at Argonne National Laboratory normally operates at an average beam current of 14 to 15 μA, accelerating protons from 50 to 450 MeV 30 times per second. The beam current is limited b

Focusing and accelerating fields in a radiofrequency quadrupole (RFQ) accelerator are usually obtained from a potential function limited to two terms. The higher order multipole terms are not included because they are difficult to calculate and their

The intense pulsed neutron source (IPNS) rapid cycling synchrotron (RCS) is used to accelerate protons from 50 MeV to 450 MeV, at a repetition rate of 30 Hz. The original ring design included two identical rf systems, each consisting of an accelerati

The IPNS RCS is a rapid cycling synchrotron used to accelerate protons from 50 MeV to 450 MeV, 30 times per second. Currently, two single-gap, ferrite-loaded coaxial cavities, located 180/spl deg/ apart, provide a total peak accelerating voltage of a

In the Intense Pulse Neutron Source (IPNS) a 50-MeV Alvarez drift-tube linac has been in operation since 1961 when it was commissioned as the injector for the Zero Gradient Synchrotron. In 1983, the original IPNS H/sup s/ource was converted to a groo

The Intense Pulse Neutron Source (IPNS) Rapid Cycling Synchrotron (RCS) accelerates 50 MeV protons to 450 MeV 30 times per second for spallation neutron production. Average current from the RCS has recently exceeded 16 {micro}A with peak instantaneou

Phase modulation (PM) is used to increase the current limit in the IPNS RCS. A device referred to as a scrambler introduces a small oscillating phase between the two RCS rf cavities at approximately twice the synchrotrons frequency, f{sub s}. The mod

The use of Second Harmonic (SH) rf is being investigated to increase the RCS current limit. Hofmann-Pedersen distributions are employed to provide analytical guidance. The SH phase θ, is optimized using a numerical analysis to maximize transmission
