Due to the effects of eddy currents and parasitic capacitance, the electrical characteristics of superconducting magnets are not completely inductive; instead, they are frequency dependent functions. This paper develops a method of accurately measuri

A method of expanding the 1700 MeV, 100 mA proton beam of the APT linear accelerator onto the 19 by 190 cm target has been devised using eight ferrite dipole magnets. These magnets deflect the beam in the x and y-plane, and thereby paint the target a

The beam diagnostics for the Los Alamos Proton Storage Ring (PSR) are being upgraded in several areas, including the closed-orbit beam-position system, the high-frequency longitudinal and transverse beam diagnostics, and the extraction-line beam-posi

A logarithmic-ratio beam position monitor (BPM) circuit has been designed that operates directly from radio frequency signals in the 100-MHz to 500-MHz frequency range. The circuit uses four logarithmic amplifiers, a pair for each channel. One amplif

The logarithmic ratio of the signal amplitudes from beam-position probe-electrodes provides a normalized real-time analog signal that is more linear in beam displacement than other signal-processing techniques for circular cross-section, beam-positio

This paper describes a simple 2D beam-rastering system to uniformly spread a 100-mA 6.7-MeV CW proton beam over a 50-cm by 50-cm beam stop. The basic circuit uses a 20-mF capacitor bank, a IGBT (insulated gate bipolar transistor) full-wave inverter,
