First Beam Tests for the Prototype LHC Orbit and Trajectory System in the CERN-SPS

The first beam tests for the prototype LHC orbit and trajectory system were performed during the year 2000 in the CERN-SPS. The system is composed of a wide-bande time normaliser, which converts the analogue pick-up signals into a 10 bit position at 40 MHz, and a digital acquisition board, which is used to process and store the relevant data. This paper describes the hardware involved and presents the results of the first tests with beam
