The median plane magnetic field of the SCC magnet (Peak field 5.8T) has been measured over its operating range and upto 29 inch radius. The complete map of 360 degree at one degree interval is obtained in less than 100 minutes measuring nearly 100K field values with radial interval of 0.1 inch. The software of the PC based mapping system works in a Client-Sever environment, maintaining TCP communication between the mapping mechanism controller station as Server and the operator's Console station as Client. The client-server developed using Labview and Windows console program respectively, provides a reliable and easily modifiable GUI and also fast hardware control from the PCs' running Windows-XP. The server program supports remote client control of motors and control and operation of digital integrator & NMR jig along with the collection and logging of measured data. The client program also supports online preliminary display and analysis of field data. The results indicate the correctness of the magnet assembly and measurement system. After coil-centering and shims placement the maximum first harmonic in the fields obtained are less than 16, 12 and 7 Gauss respectively in central, middle and extraction region at all magnet excitation. © PCaPAC 2006 - 6th International Workshop on Personal Computers and Particle Accelerator Controls, Proceedings.All right reserved.
