Stripline beam position monitors (BPMs), located in regions of large dispersion, are being used to monitor the relative energy spread of beams injected into the SLC damping rings. Several BPMs have been configured so that the quadrupole moment as well as the dipole moment (beam position) information is generated in hardware. The dipole moment is subtracted in quadrature from the quadrupole moment to produce a signal which is related to the beam width but which is independent of the beam position. Data reduction and averaging is accomplished in the control system microprocessors. Additional data handling occurs in the host computer. Beam width signals from the devices are used in conjunction with RF phase adjustments to minimize the energy spread of the beams. A computer controlled feedback loop has been developed to oversee the process of energy spread manipulation.
