H+- and H--beam position and current jitter at LANSCE

During the CY2005 and CY2006 Los Alamos Neutron Science Center (LANSCE) beam runs, beam-development shifts were performed in order to acquire and analyze beam-current and beam-position jitter data for both the LANSCE H
⁺
and H
^-
beams. These data were acquired using three beam-position monitors (BPMs) from the 100-MeV Isotope Production Facility (IPF) beam line and three BPMs from the Switchyard (SY) transport line at the end of the LANSCE 800-MeV linac. The two types of data acquired, intermacropulse and intramacropulse, were analyzed for statistical and frequency characteristics as well as various other correlations including comparing their phase-space characteristics in a coordinate system of transverse angle versus transverse position. This paper will briefly describe the measurements required to acquire these jitter data, the analysis of these data, and some interesting implications to beam operation.
