Administrative history

The ERASME project began at CERN in 1970. The design was based on experience gained by the Data Handling (DD) and Track Chamber (TC) divisions in the construction and operation of systems for handling bubble chamber film.

The first ERASME measuring table came into operation in 1973, and was followed by five more. Tables based on the CERN design were also used in Bonn and Madrid. Digital Equipment Corp. (DEC) computers were the norm, both for table control (PDP 11) and for central data handling (PDP 10 and VAX 780).

ERASME was used for all aspects of film analysis but the workload became so large that some tasks had to be subcontracted to the simpler Bessymatic tables, and the two systems became highly complementary.

The ERASME measuring table was an instrument developed for the analysis of 70 mm film from the 3.7 m bubble chamber, Big European Bubble Chamber (BEBC), but was also used at an early stage with the 50 mm film from the 2 m bubble chamber. Not a fully automated instrument, it could perform the full sequence of operations (scanning and measurement) with considerable operator intervention in both stages.
