the activation — The Ellison Activatron-110. This 150 KV neutron gener ator is a simply designed unit that will produce up to 14 MEV neutrons from a Deuteron-Tritium reaction. Its size, mobility and high yield — more than ΙΟ10 n/sec—make it an excellent choice for the laboratories of radiochemists, geochemists, criminologists, metallurgists and other scientists who need efficient activation analysis in a manageable, moderately priced setup. The Activatron has a unique ion source that takes its DC operating voltage from the 150 KV accelerating voltage. No electronic circuits or isolation transformers are needed. The main ad vantage of this design is that both the accelerating tube and the source are im mersed in an oil tank; the outside case is at ground potential for the complete safety of the operators. Complete specifications and prices are contained in our bulletin describing the Activatron-110 and the 400 series analyzers (below).
Activation
and Analysis
from TMC and the analysis... The portable 400 series 400-channel pulse analyzer handles the accumulation and storage of the gamma ray pulses from the sample activated by the Activatron-110. It will store data in memory groups of 400 chan nels (1 group); 200 channels (2 groups); 100 channels (4 groups). Data can also be transferred from one half of the memory to the other, or from one quarter to another within the same half. Data can be examined while it is being accumulated on the cathode ray tube display in the analyzer. For analog readout, paper tape punch, reader, IBM typewriter and digital printers may be used. accessories The Model 522 pushbutton Resolver/lntegrator functions as either a resolver or an integrator and does not need intermediate taping equipment. As a resolver it makes data availa ble from a quarter or a half of the analyzer memory and adds it to or subtracts it from data in the adjacent quarter or half. This enables the operator to remove reference peaks from a complex spec trum and leave only the unknown elements. As an integrator it integrates memory-stored information in any band of channels from 0 to 399 in one operation and a choice of two modes — Normal (summa tion and total in the last channel); Subtotal (running subtotal). The Model 500P High Speed Printer prints out channel number and data on 3-inch wide paper tape at 5 lines per second. It has a built-in high voltage supply that will power up to four detectors.
