critical read-outs, is essential, as it al lows the operator to make the correct decision.

The instrument is available in two versions; the basic 'R' version and a complete version, which give an A-scan display and the possibil i ty of interfacing a digital calibre valuation for direct reading of real thickness for automatic evaluation of the ultrasonic velocity.

It includes an internal data logger to memorize thickness data (up to 8000), according to a linear or matrix sequence; data may be assigned up to 99 files. It is possible to recall data on the display or download it to a PC or printer: the operator may decide to memorize pertinent data wi th the A-scan which appear on the PC video also wi th the oscillograms of interest.

X-ray imaging cameras A new range of CCD cameras for X-ray imaging has been introduced by Micro Photonics. The X-ray imager series manufactured by Photonics Science were designed for high resolution topography and real-time

dynamic imaging. An Imager comprises a CCD camera fitted wi th an X-ray scintil lator fibre optically coupled to an image intensifier. The cameras output the intensified image at video rates (30 frames s -1) and so are suitable for many types of dynamic X-ray imaging applications.

The standard scintil lator is polycrystall ine gadolinium oxysulphide with an energy range from 5 keV to 200 keV. The scinti l lator can easily be removed from the camera and an alternative scintil lator fitted into place. The Imager cameras include different sizes of input scintil lators with corresponding coherent fibre optic links to the intensifier and CCD chip. The result is a range of combinations of input image size (12 ram, 18 ram, 50 mm and 1 50 mm diagonal) and camera resolution (from 150 #m for large area versions to better than 18/~m for high resolution versions). Imaging software is also available for the acquisit ion and manipulation of images in a Windows- l ike environment.

The cameras can be used for whi te l ight and monochromatic X-ray topography. Applications include crystallography, microradiography and interferometry. In the physical sciences they can be used for materials properties analysis such as

Four-channel field recorder

The four-channel field recorder introduced by Astro- Mad offers a range of features including laser quality printing (300 dpi), high-speed monitor, internal rechargeable battery, 256 kbyte RAM per channel, floppy disc drive and built-in signal conditioning. Designated as the Dash IV, the unit records voltage, current, temperature, strain, pressure, etc. in real time at frequencies from DC to 20 kHz with chart speeds up to 200 mm s -1 . It also stores captured data for later playback in any format.

Because of its rugged design and reliability, it is suited for demanding applications in the aerospace, telecommunications, automotive, pulp and paper, electric utility, metals manufacturing, and other industrial, scientific, and educational fields.

Operation is simple. Menus displayed on the monitor guide the user through the programming sequence. Ten soft keys perform different functions at different times as determined by the internal software and simplify the changing of settings. In addition, an encoder wheel simplifies and speeds up the setting of precise gain and waveform position.

It has built-in signal conditioning, which will accept signals in the range of 50 mV full scale to 250 V (isolated,
