![]() ![]() ![]() The 1/4 Mbyte more » of high speed CMOS static RAM appears either as a FIFO, or mapped memory depending upon a bit in the CSR. Each card has a 16-bit control-status register (CSR), the bits of which configure the hardware and define the hardware options. The data is buffered by a high-speed asynchronous FIFO following the A/D converters, and written into Data Memory on the card, either directly or after processing by an on-board digital signal processors (DSP). The card accepts two multiplexed analog data streams at a 1 MHz rate, and digitizes and stores the data for subsequent transfer through VME to a host computer. This paper discusses the design of a prototype data acquisition (DAQ) card for the ZEUS calorimeter. On field contour and flux line plots, lines of intersection between the coils and the plotting plane are also shown. Plots of field contours, field profiles, flux lines, field magnitude along a flux line, and forces can all be obtained at the option of the user. ![]() In addition, each column of numbers on each page is appropriately labeled. Each page of output is labeled with the problem title the time, machine and data of the run and the version number and compile date for EFFI. EFFI produces both printed and graphical output. If no errors are detected, the program automatically expands memory to the size required for the problem. To aid the user in correcting mistakes, each error detected produces a diagnostic giving the objection to the data and the number of more » the offending data card. All input to EFFI is format free, and is checked for validity before any calculations are done. Several examples, including the magnet design for MFTF and a divertor design for a Tokamak are used for illustration. The preparation of input to the code and the output options available are described. EFFI calculates magnetic flux lines, fields, forces, and inductance for an arbitrary system of coils made from circular arc and/or straight segments of rectangular cross section conductor. ![]()
