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-band time normaliser, which converts the analogue pick-up signals into a 10 bit position at 40MHz, 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.
