The H1 experiment at the electron-proton collider HERA has built a new fast track trigger to increase the selectivity for exclusive final states, especially those with heavy quarks, and to cope with the higher background rates after the HERA luminosity upgrade. Hits measured in the central jet chamber of H1 are combined to track segments by performing 5 middot 1012 mask comparisons per second using...

Hits measured in the central jet chamber of H1 are combined to track segments by performing 5times1012 mask comparisons per second using content addressable memories (CAMs). These...
