Nova alignment and laser diagnostics systems - 2

Requirements for diagnostic-data acquisition and processing include rapid turnaround, effective interfacing with the alignment and power-conditioning controls, preservation of data under failure conditions, options for local or control-room modes of operation, and portability of the hardware required for off-line troubleshooting and calibration. The major elements of a digital system which meets these requirements are shown. A further potential difficulty, operating in the presence of prompt radiation from the target, has been avoided by locating all laser diagnostic components outside of the target room
