Abstract
The recently commissioned Recoil Mass Spectrometer (RMS) at the Holifield Radioactive Ion Beam Facility (HRIBF) is described. Consisting of a momentum separator followed by an E-D-E Rochester-type mass spectrometer, the RMS is the centerpiece of the nuclear structure endstation at the HRIBF. Designed to transport ions with rigidities near K = 100, the RMS has acceptances of ±10% in energy and ±4.9% in mass-to-charge ratio. Recent experimental results are used to illustrate the detection capabilities of the RMS, which is compatible with many detectors and devices.

Funding
This paper is dedicated to the memory of J.D. Garrett. We wish to thank the HRIBF Operations and Facility Support Personnel for their huge contribution to our efforts. We also wish to thank the many HRIBF Users whose data are shown here to illustrate the capabilities of the RMS. The RMS was initiated by Vanderbilt University and the individual elements of the RMS were built by Danfysik A/S. The RMS was funded by the Georgia Institute of Technology, Idaho Nuclear Engineering Laboratory, Louisiana State University, Oak Ridge Associated Universities, Oak Ridge National Laboratory, State of Tennessee, UNISOR, University of Maryland, University of Tennessee, U.S. Department of Energy, and Vanderbilt University. Oak Ridge National Laboratory (ORNL) is managed by Lockheed Martin Energy Research Corp. for the U.S. Department of Energy (DOE) under contract DE-AC05-96OR22464. This research was also supported by DOE through Contract Nos. DE-FG02-96ER40978 (Louisiana State University), DE-AC05-76OR00033 (Oak Ridge Institute for Science and Education), DE-FG02-96ER40963 (University of Tennessee), DE-FGO5-87ER40407 (Vanderbilt University), DE-FG02-96ER40958 (Georgia Institute of Technology), and DE-FG05-87ER40361 (Joint Institute for Heavy Ion Research). The Oak Ridge National Laboratory Postdoctoral Research Associates Program is administered jointly by the Oak Ridge National Laboratory and the Oak Ridge Institute for Science and Education. The Joint Institute for Heavy Ion Research is supported by its members, the University of Tennessee, Vanderbilt University, and Oak Ridge National Laboratory.
