MOPOB12	A High Bandwidth Bipolar Power Supply for the Fast Correctors in the APS Upgrade	ion, power-supply, controls, ISOL	96
	J. Wang, G.S. Sprau ANL, Argonne, Illinois, USA
	Funding: Work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under Contract No. DE-AC02-06CH11357. The APS Upgrade of a multi-bend achromat (MBA) storage ring requires a fast bipolar power supply for the fast correction magnets. The key performance requirement of the power supply includes a small-signal bandwidth of 10 kHz for the output current. This requirement presents a challenge to the design because of the high inductance of the magnet load and a limited input DC voltage. A prototype DC/DC power supply utilizing a MOSFET H-bridge circuit with a 500 kHz PWM has been developed and tested successfully. The prototype achieved a 10-kHz bandwidth with less than 3-dB attenuation for a signal 0.5% of the maximum operating current of 15 amperes. This paper presents the design of the power circuit, the PWM method, the control loop, and the test results.

TUPOA24	Beam Intensity Monitoring System for the PIP-II Injector Test Accelerator	ion, pick-up, FPGA, linac	330
	N. Liu, J.S. Diamond, N. Eddy, A. Ibrahim, N. Patel, A. Semenov Fermilab, Batavia, Illinois, USA
	Funding: This work was supported by the U.S. Department of Energy under contract No. DE-AC02-07CH11359. The PIP-II injector test accelerator is an integrated systems test for the front-end of a proposed CW-compatible, pulsed H⁻ superconducting RF linac. This linac is part of Fermilab's Proton Improvement Plan II (PIP-II) upgrade. This injector test accelerator will help minimize the technical risk elements for PIP-II and validate the concept of the front-end. Major goals of the injector accelerator are to test a CW RFQ and H⁻ source, a bunch-by-bunch MEBT beam chopper and stable beam acceleration through low-energy superconducting cavities. Operation and characterization of this injector places stringent demands on the types and performance of the accelerator beam diagnostics. This paper discusses the beam intensity monitor systems as well as early commissioning measurements of beam transport through the Medium-Energy Beam Transport (MEBT) beamline.

	P. Piot Fermilab, Batavia, Illinois, USA A. Halavanau Northern Illinois University, DeKalb, Illinois, USA
	This paper discusses the implementation of a PYTHON-based high-level interface to the Fermilab ACNET control system. We will especially present examples of applications which include the interfacing of an ELEGANT beam-dynamics model to assist lattice matching and an automated emittance measurement via the quadrupole-scan method.

TUPOB21	MuSim, A Graphical User Interface for Multiple Simulation Codes	ion, simulation, resonance, proton	535
	T.J. Roberts, Y. Bao Muons, Inc, Illinois, USA Y. Bao UCR, Riverside, California, USA
	MuSim is a user-friendly program designed to interface to many different particle simulation codes, regardless of their data formats or geometry descriptions. It presents the user with a compelling graphical user interface that includes a flexible 3-D view of the simulated world plus powerful editing and drag-and-drop capabilities. All aspects of the design can be parameterized so that parameter scans and optimizations are easy. It is simple to create plots and display events in the 3-D viewer, allowing for an effortless comparison of different simulation codes. Simulation codes: G4beamline 3.02, MCNP 6.1, and MAD-X; more are coming. Many accelerator design tools and beam optics codes were written long ago, with primitive user interfaces by today's standards. MuSim is specifically designed to make it easy to interface to such codes, providing a common user experience for all, and permitting the construction and exploration of models with very little overhead. For today's technology-driven students, graphical interfaces meet their expectations far better than text-based tools, and education in accelerator physics is one of our primary goals.

	Y. Bao UCR, Riverside, California, USA T.J. Roberts Muons, Inc, Illinois, USA
	Funding: This work is supported by Muons, Inc. MuSim is a new and innovative graphical system that allows the user to design, optimize, analyze, and evaluate accelerator and particle systems efficiently. It is designed for both students and experienced physicists to use in dealing with the many modeling tools and their different description languages and data formats. G4beamline [1] and MCNP [2] have been implemented into MuSim in previous studies. In this work, we implement MAD-X [3] into MuSim so that the users can easily use the graphical interface to design beam lines with MAD-X and compare the modeling results of different codes.
