“…An adaptation of the neuton TV pinex was used to image fuel motion in fuel pins undergoing planned failure at the Transient Reactor Test (TREAT) Facility at Idaho National Engineering Laboratory. 10 Cameras tracked the entire transient fuel-pin failure sequence. An FPS camera was used in one of the TREAT experiments."…”

Two ultrafast-scan (<8 ms/field) television (TV) camera prototypes have been developed for closed-circuit data-acquisition applications. The line and field rates are quasi-continuously adjustable. The number of lines, the integration duty cycle, and the scan direction are among the other adjustable parameters. Typical resolution at the fastest scan rate is >500 TV lines per picture height with a corresponding dynamic range (to light input) of more than 100. The cameras use the unique properties of FPS vidicons and specially designed electronics to achieve their performance levels and versatility.The advantages and disadvantages of FPS vidicons and of antimony trisuifide and silicon target materials in such applications are discussed in detail.All of the electronics circuits are discussed. The sweep generator designs are treated at length because they are the key to the cameras' versatility. Emphasis is placed on remotely controllable analog and digital sweep generators. The latter is a complete CAMAC-eompatible subsystem containing a 16-function master arithmetic logic unit.Pulsed and cw methods of obtaining transfer characteristics are described and compared. The effects of generation rates, tube types, and target types on the resolution, determined from contrast-transfer-function curves, are discussed.Several applications are described, including neutron TV pinhole, TREAT, and barium-release experiments.
