Phys. Rev. ST Accel. Beams 5, 072803 (2002) [10 pages]Noninvasive single-bunch matching and emittance monitor
On-line monitoring of beam quality for high brightness beams is possible only by using noninvasive instruments. For matching measurements, very few such instruments are available. One candidate is a quadrupole pickup. Therefore, a new type of quadrupole pickup has been developed for the 26 GeV Proton Synchrotron at CERN, and a measurement system consisting of two such pickups is now installed in this accelerator. Using the information from these pickups, it is possible to determine both injection matching and emittance in the horizontal and vertical planes, for each bunch separately. This paper presents the measurement method and some of the results from the first year of use, as well as comparisons with other measurement methods.
