Abstract
A scenario for central tracking at future hadron colliders based on small diameter scintillating fibres is outlined. Assemblies of these fibres within fused multibundles were produced and test results with a small prototype of a tracker shell are reported: spatial resolution of 35 μm and two-track resolution of 83 μm were achieved. The importance of local light emission in these fibres is discussed together with the results obtained from newly synthesized scintillators of large Stokes shifts. Monte Carlo simulations of top, Higgs, and minimum bias events show that tracking with fine-grain scintillating fibres is well feasible and occupancy at 1034cm−s− luminosity does not present problems.
