MANIFOLD PUMP TUBMG
The Quanta System consists of a GEOS single or dual parameter 4096 channel analyzer interfaced to the new DEC PDP-11/20 4K-16 bit computer plus application-oriented program soft ware. The instrument offers several advantages in nuclear research and an alytical applications : the analyzer and the computer may be functionally iso lated from one another and used inde pendently, thus the computer can be used for data reduction while the ana lyzer is used for data acquisition; new programs can be debugged without de stroying experimental data; and data may be accumulated through either computer software control or direct op erator control of the analyzer. Basic system prices begin at below $30,000.

413 Auger Spectrometer
Instantaneous oscilloscope display of Auger peaks is now possible with a cy lindrical mirror spectrometer. The in strument reduces the typical 10-min scan time for analyzing Auger electron spectra to msec. As the instrument detects picogram quantities of ele ments, it is particularly useful in solving problems of surface contamination.
