Book Description
An extensive data acquisition and analysis system has been implemented for experiments on the ARGUS laser. The system is based upon a PDP-11/40 minicomputer and CAMAC interfaces. Highspeed transient digitizers, calorimeter digitizing modules and time integrated data are interfaced through CAMAC over a fiber optic serial highway. The system allows for dynamic definition of the experimental environment by an operator, automatic data acquisition during a shot. Two interactive graphics terminals allow experimenters real-time access to target shot data.

Book Description
Much of the target diagnostics data from the ARGUS laser are acquired through a CAMAC interface system, including equipment on a CAMAC serial highway. A scheme has been developed which allows a very general capability for dynamically defining the experimental configuration such that the serial highway is invisible to the controlling program. High level language software compiles the existence of each experimental entity in the system. As the position and description of each module is defined, a software structure is built, with each entry containing the information to be provided to the CAMAC handlers during operation of the equipment. Provision is made to allow tight loops at the lowest software level for critical high speed data acquisition. Currently, the serial highway is operated at a one megabit rate, allowing 24 bit CAMAC words to be transferred at a 5 KHz rate.

Book Description
A variety of systems are required for adequate diagnostics of laser fusion experiments. Picosecond scale temporal measurements are typically made with ultrafast streak cameras. Visible and x-ray sensitive streak cameras with resolutions of 6 psec and 15 psec, respectively, and dynamic recording range in excess of 103 are in regular use on experiments at Livermore. The characteristics of these cameras and their applications to target experiment diagnostics are described. The development and testing of a prototype ultrafast framing system is discussed. Because of the need for ''real time'' data acquisition, analysis, and control systems, techniques for providing directly computer interfaced image data from streak and framing cameras and optical imaging systems are being developed. The status of these developments and the characteristics of the computer interfaced data and control systems on Argus and Shiva are summarized.
