Fermilab is jointly developing capabilities in high gradient and high Q superconducting accelerator structures based on the 1.3 GHz TESLA technology. Based on an INFN/TESLA design, a wire-position-monitor (WPM) system is integrated to monitor cavity alignment and cold mass vibrations. The system consists of a reference wire carrying a 325 MHz signal, 7 stripline pickups (per cryomodule), and read-out electronics using direct digital signal down-conversion techniques. We present technical details of the system, and preliminary results on resolution and stability measured at a mock-up test stand.

The Fermi National Accelerator Laboratory (FNAL) High Intensity Neutrino Sources (HINS) is a research project to address accelerator physics and technology questions for a new concept, low-energy, high-intensity long pulse H- superconducting linac. HINS will consist of a 50 keV ion source, a 2.5 MeV Radiofrequency Quadrupole (RFQ), and a 10 MeV room temperature spoke resonator acceleration section followed by superconducting spoke resonator acceleration sections. At this time a proton ion source and the RFQ module have operated with beam. This paper will present the results of first beam measurements through the HINS RFQ.
