[en] The operating environment for the DIII-D tokamak places requirements on health safety neutron monitoring which differ from previous health safety monitoring used on Doublet III. The new operating environment requires monitoring to include neutrons generated during tokamak shots and neutrons generated during neutral beam conditioning. Since neutral beam conditioning is performed asynchronously to the tokamak operation, a system of continuous monitoring is required. The original method for monitoring neutrons was performed using the DIII-D diagnostic data computer system, since only shot-related information was necessary. To perform continuous monitoring, a separate microcomputer-based system was implemented. The system was designed to use an IBM PC AT interfacing the neutron detectors through a GPIB bus with a single CAMAC crate. The software was selected to perform multi-tasking utilizing the concurrent PC DOS operating system with all applications developed in the C language. The primary requirements included monitoring the neutrons continuously, ensuring that health safety limits were not exceeded, and prevention of further operation when a limit was approached. The purpose of this paper is three-fold. First, the system will be described in terms of the hardware configuration and the software methods used collecting, managing, and displaying the data. Included in the description will be the justifications and trade-offs on selecting the exact hardware and software used. Second, the problems encountered in implementation due to non-compatible hardware and software will be covered. This discussion will focus on problems which are difficult to anticipate without direct experience with the exact hardware and software configuration. Third, guidelines which can be used to prevent some of the compatibility problems that can occur will be discussed. 4 figs
