Abstract

The Aleph detector is installed on the LEP electron-positron storage ring. Its central tracking detector, a Time Projection Chamber, has about 50,000 channels of sampling electronics. The digitized signals are processed by 72 double width Fastbus modules, built around an MC 68020 processor. The Time Projection Processor will be described and the solutions, both hardware and software, adopted to run and manage such a complex system in a Fastbus-VAX environment will be discussed. Practical experience with the system will be reported.
