Abstract

The Pixel Luminosity Telescope (PLT) is an innovative luminosity monitor which is planned as an upgrade for the CMS detector at the LHC. It uses pixelated single-crystal diamonds as the active sensor material bumpbonded to standard CMS pixel readout electronics. The PLT makes use of a presently unused feature of the pixel readout chip which was designed to provide a hit-over-threshold signal to a hardware trigger processor. This feature will produce a bunch crossing (25 ns) 'hit' signal that can form the basis of luminosity information at the hardware level. We will report on the first successful use of this 'Fast-Or' signal to self-trigger on beta particles from a source using a diamond pixel detector. Expected performance of the PLT based on Pythia simulations is also detailed.
