Abstract

All magnetic measurements of the CERN SC2 magnet were done with Hall-plates. The principal element of the measuring gear was a 3.5m long bar with 100 Hall-plates mounted on a computer-controlled turn-table. The Hall-voltages were scanned, converted into field values and stored on tape. For special regions other Hall-plate arrangements were used. The field maps were evaluated in terms of mean radius, frequency, n-value, etc. versus energy. The optimum field for capture near the centre, acceleration and transmission through the extraction system was calculated. Shimming was required near the centre and in the channel-regenerator region. The same programs as for the original design were used. The programs used will be briefly described.
