	Funding: Work supported by the United States Department of Energy, National Nuclear Security Agency, under contract DE-AC52-06NA25396 Initial acceleration of the beams in the LANSCE linear accelerator at Los Alamos National Laboratory is still presently accomplished through the use of two 750-keV Cockcroft-Walton (CW) based injectors. To reduce long-term operational risks and to realize future beam performance goals, plans are underway to replace the existing H⁺ CW injector with a modern replacement, 4-rod Radio-Frequency Quadrupole (RFQ) based front end. Significant technical progress has been made since we last reported on this project. Status and progress of the design and fabrication of the RFQ, the RF system, beam transports, and integrated accelerator test stand will be discussed.

	LANSCE provides H⁻ and H⁺ beams to several user facilities for fundamental and applied research, including a 100-MeV, 250-μA proton beam to the Isotope Production facility (IPF). Each beam species is initially accelerated to 750 keV in separate Cockcroft-Walton (C-W) accelerators. Due to the age and possible failure modes of the C-W’s and the potential impact of a C-W failure to the IPF program, we have begun the process of replacing the aging H⁺ C-W with a modern Radio Frequency Quadrupole (RFQ) accelerator-based system. In addition, the complexity of combined species operations imposes further restrictions on the beam performance and configuration that must be incorporated into the design process. This paper will cover the physics design requirements of this new RFQ and the expected performance based upon the results of PARMTEQM simulations.

LANSCE provides H⁻ and H⁺ beams to several user facilities for fundamental and applied research, including a 100-MeV, 250-μA proton beam to the Isotope Production facility (IPF). Each beam species is initially accelerated to 750 keV in separate Cockcroft-Walton (C-W) accelerators. Due to the age and possible failure modes of the C-W’s and the potential impact of a C-W failure to the IPF program, we have begun the process of replacing the aging H⁺ C-W with a modern Radio Frequency Quadrupole (RFQ) accelerator-based system. In addition, the complexity of combined species operations imposes further restrictions on the beam performance and configuration that must be incorporated into the design process. This paper will cover the physics design requirements of this new RFQ and the expected performance based upon the results of PARMTEQM simulations.
