Abstract

Six flying wire systems have been installed in the Fermilab Accumulator to measure the transverse beam profiles during antiproton stacking and extraction, and the beam momentum distribution during deceleration through transition. The authors summarize the hardware and software features of the accumulator flying wire systems. Each system measures a transverse beam profile by passing a 25- mu carbon filament through the beam transversely, and recording the flux of secondary particles which are produced from the collisions between the beam particles and the wire. The wire motion, data acquisition, and communication with the control system are managed by a 32-b VME-based microcomputer system. The measured effect of wire passages on beam emittance is described.<>
