Design and commissioning of beam position monitors in the IUCF cooler injector synchrotron

IUCF is completing construction of the cooler injector synchrotron (CIS). A secondary emission profile monitor system (harp) is used for beam profile and emittance measurement. The harp design was patterned after a design used for many years at Fermilab. Two, non-interceptive, beam position monitor (BPM) systems have been built to facilitate and enable commissioning and operation. In the 7 MeV injection beamline, high input impedance front-end amps are used to detect the signal from 4-quadrant, electrostatic pickups. The beam in this area will average 200 /spl mu/A peak, with a pulse width of 100-200 /spl mu/s and repetition rate of up to 5 Hz. In the CIS ring, 4-quadrant, elliptically shaped electrostatic pickups are used for impedance matching to the beamline. An electric field modeling program was used to determine the parameters of the plates in the pickup. Logarithmic amplifiers are used to detect the beam in the CIS ring, providing a linear output and an extended range. A time of flight system is also discussed.
