run muudinr control and a positive flow meter. Designed for counting soft beta radiation, the unit can count alpha radiation in the presence of beta and can discriminate between beta radiation of various energies when used in the proportional region. The company's rubber hydrochloride window is said to be easily installed to reduce contamination or vapor transmission from liquid or moist samples. Technical Associates. P-33
SAMES Electrostatic Generators, producing substantial amounts of output power at voltages up to 600 kv, are the first such generators ever designed for day-to-day industrial use. They're marketed in the U. S. exclusively by Sorensen. Output voltage is very nearly pure d-c, marked by the almost complete absence of ripple or other a-c components. Voltage regulation ranges from 4% to 0.33% for medium stability models and from 0.1% to 0.001% for high stability models. You'll find these advanced high-voltage d-c sources described in the new 6-page SAMES brochure. A new 32-page Sorensen catalog is also available which lists more than 400 models of high-precision power supply equipment and gives valuable selection and application data.
