We have been investigating the performance of scintillating pad detect
ors, individual small tiles of scintillator that are read out with wav
elength-shifting fibers and visible light photon counters, for applica
tion in high luminosity colliding beam experiments such as the DO Upgr
ade. Such structures could provide ''pixel'' type readout over large f
iducial volumes for tracking, preshower detection and triggering.
