74.146 'Progress in the development of an interacting computer program for magnetic field design and analysis in two and three dimensions' Rutherford High Energy Lab., Didcot, Berks, UK (July 1973) 23 pp There has been a demand for an interactive computer program which would enable a magnet designer to make a rapid assessment of the performance of a given geometry. Such a program (iFUN was described at the International Conference on Magnet Technology at Brookhaven in September 1972. By a series of simple commands the user can draw in current or iron elements, and at the same time display a picture of the geometry. Further commands enablc the fields to be computed at any point in space and the results to be displayed graphically. Work is now proceeding on new subroutines for the three-dimensional version with provision of a facility for describing the shapes of the ends of field windings. 'Race track' ends can now be handled by the program and other contours will be available.

74.147 'Structure and software facilities implemented in a man/machine interactive pattern recognition system' Presented at: Real lime Programming, 3rd Furopean Seminar, Ispra, Italy, (16 18 May 1973), 31 pp An interactive computer controlled c.r.t. digitizer is being used for bubble chamber picture recognition in the field of highenergy physics. Up to four devices can be connected to a Control Data Cyber-72 operating under Kronos system. The main features of the c.r.t.-digirizer is described. The software structure of the real-time multiprocessor systcm appears to the user as a virtual computer, named meta-machine, Three topics are presented: (I) the hardware structure of the meta-machine, (2) the metalanguage used to define the pictureprocessing strategies and operator interventions; (3) the control and debug ging used to introduce modifications on the picture strategies while the system is running. An example illustrates the metamachine programming.
