[en] A microprocessor control system is described, which will monitor room interlocks, enable the firing of high-voltage pulsers, and display the safety status of a 10 kJ-laser laboratory. The system will increase the safety of personnel by enforcing their exclusion from dangerous areas, by detecting breaches of security safeguards, and by disabling high-voltage power supplies. The microprocessor system allows five logical modes of operation corresponding to differing uses of areas in the laboratory; a safety procedure must be followed for each of these modes. The microprocessor follows the operator through prescribed steps of the procedure by monitoring associated door and area-interlock switches. After completion of the procedure, the microprocessor activates the corresponding enabling outputs, which permit the operator to energize high-voltage power supplies. Should safety be breached during or after completion of a procedure, e.g., should a door wrongly open, the microprocessor will cancel any enable command and will return to a safe state
