Searching for Antiproton Decay at the Fermilab Antiproton Accumulator

This paper describes an experimental search for antiproton decay at the Fermilab Antiproton Accumulator. The E868 (APEX) experimental setup is described. The APEX data is expected to be sensitive to antiproton decay if the antiproton lifetimes is less than a few times 100 000 years.

Lattice Function Measurements in the Fermilab Accumulator Ring

The betatron phase advance between two points in a storage ring can be very accurately determined from a transverse beam transfer function measurement with DC beam. The phase advance can be determined from the difference in the phase response between an upper betatron sideband (N+Q line) and a lower betatron sideband (N-Q line) in an open loop network analyzer measurement between a kicker and a...

RF Heating and Temperature Oscillations due to a Small Gap in a PEP-II Vacuum Chamber*

Wake fields excited in a small gap of a vacuum chamber by ampere beams can have enough amplitude to heat the chamber. The electric component of these fields can be above the arcing limit. Usually flange connections in a vacuum chamber contain a vacuum gasket and an inner RF gasket. If a small gap occurs between the RF gasket and flange surface, wake fields can heat the flanges. The flanges are ...
