G) G "Ri New MRC Model X-86N-II Diffractometer Attachment Make your x-ray investigations of materials more comprehensive with this improved, precision instrument. Its diffraction angle range has been increased to 0 ° - 1 6 0 ° 2Θ. The new chamber has a pressure range from 1 0 - 5 m m . Hg. high vacuum to 150 psi with gas environments. Temperature ranges reach 1600°C with the rhodium-platinum ribbon heater and 2 0 0 0 ° C with the tantalum heating unit. An optional Re ele ment extends high temperature range to 2800°C. For cryogenic studies to - 1 7 6 ° C , a special copper platform for liquid nitrogen flow is in cluded, as is the power supply. The vacuum-tight environmental chamber consists of a polished aluminum cover and shell which is water-cooled. The special vacuum inlet is in the cover for rapid pumpdown time and ease of attachment of a diffusion pump. Curved beryllium windows reduce x-ray intensity by no more than 2 4 % for copper radiation. Alignment controls outside the chamber permit specimen adjust ment at vacuum and at temperature, and there is a sighting window for pyrometric measurements. Felt-lined carrying and storage case included for each unit. Model X-86N-II is designed for use with the Norelco Wide Range Diffractometer.
