Nucleus PCA II Software: Radon II

The radon II software is a complete analysis package for calculating the amount of radon that has been collected in charcolal canisters. It provides the correctionfactors for three canister types presently used in the EPA’s RPM program.

Customers’ measurement data can output to a printer or disk file. The printer output consists of letter form containing all customer, acnister, and calculation data in a file that can be customized by the user. The disk file contains all of the above data in 33 lines of asc ii code.

A database is supplied and interfaces into the software. This will allow the user to complete the data in any reporting format for state and federal radon level regulations.

Note: Must be used with an EGA or VGA graphics card and compatible color monitor.

Nucleus PCA II Software: GDR PC

This software package contains programs which enable nuclide identification for gamma spestroscopy. It performs automatic qualitative and quantitaive analysis of gamma spectra from germanium and scillation detectors.

This program is designed to run in conjunction with the PCA or PCA II cards and software in IBM XT,AT,series II model 30 or compatible 286 and 386 computers.

Multi-Detector Low Level Counting System

Who needs it?

You are interested in Tennelec because you want quality, reliability and performance. The choice of which system you need is then based upon the size of the sample, the number of samples and the minumum activity requirements. The latter dictates the counting time for each sample. If this time is in the order of 30 to 60 minutes, and many samples are to be processed , you should consider a multiple detector system.

The LB 4000 is expandable from 4 to 16 detectors. It counts and seperates alphas from betas in a single count (other system must count the sample twice to achieve this). It includes the new IBM system 2 model 30 computer with color monitor and printer. You can automatically execute your own programs at the termination of a count. And, above all else, it is a quality analytical instrument.

Low Level Counting Systems

If you are involved in low level alpha or beta counting, you need no introduction to Tennelec. Our systems are enermously popular throughout the world for one overwhelming reason – they count samples accurately and reliably. We offer a series of manuel and automatic systems for up to 2 inch diameter planchet samples utilizing either gas-flow proportional detectors.

The diversit of our product line grew as our customers needs grew and changed. The LB 4000 System is our newest low level counting system. It was designed at the request of our customers who could not find the quality and performance they expected in existing products.

Two 1 kV Supplies with Digital Displays

When we set out to design a new 1 kV power supply, we asked for everything and expected to compromise. Our engineers would have none of that. The TC 954 provides up to 1 kV and 100mA fully regulated. Precision calibration is guarenteed with a four digit display voltmeter built into the single width module. This same display will also monitor output current. Some of the other features packed into this unit include adjustable current limit with automatic shutdown, external control, and automatic ramp-up circuit. The TC 953 is even more outstanding because there are two totally independent 1 kV in a single-width NIM module. You can even run one positive and the other negative.

NIM Bin with Voltage Monitors

We make instruments better, not cheaper. This is reflected in our Standard TB3 NIM Bin which uses extruded aluminum construction, paralel wired power distribution and floating bin sockets. We now offer a Bin with an additional feature – voltage monitoring LEDs. The new TB4 gives added assurance by illuminating a gren LED on all active supply lines within regulated limits. The TB4 is the perfect mat efor the new TC 911 TURBO or our Standard TC 911 supply and it is even compatible with supplies from those other guys.

High Powered NIM Supply

427 Watts in a Compact Package

More and more of the high speed NIM instruments, particularly timing modules, exceed the NIM power standards. Previous NIM supplies designed to meet these demands were burdened with bulky heat sinks. Our new supply reduces this burden with an innovative forced air (turbo) cooling system which gave rise to its name – TC 911 TURBO. As you would expect from Tennelec, it is built tol ast and packed with features. The TC 911 TURBO includes +-6V, redundant circuit protection and optional remote power switching.

Time to Amplitude Converters

Ranges from 5 nsec to 3 msec

These new series of TACs are loaded with features. Time ranges are selected in conjuction with a twelve position rotary switch, x10 multiplier and a continously variable 0.5 to 1.5 multiplier. LEDs provide positive indication of pulse processing Built-in output delay and pulse width adjustments insure compatibility with any analog-to-digital converter. Three models are available – TC 862 TAC; TC 863 TAC/Single-Channel-Analyzer; TC 864 TAC/Biased Amplifier.

ER Series Extended Range Detectors

The extended range series promises to become the new Standard for germanium gamma detectors. It represents the best value fr dolar with an extended energy range of 10 keV to 10 MeV as compared to the 40 keV to 10 MeV range of the CP series. The ER Series is a rugged as the CP Series with a fully enclosed aluminum end-cap and offers the same neutron damage resistance as the CN Series.

All of this is possible because of technology breakthrough at Tennelec resulting in unprecedented yields of N-type material. We are prepared tos hare with you the fruits of our efforts in the form of a better detector at a better price.

CN Series N-Type Germanium Detectors

Certain applications require detectors with a wide energy range response in order to detect low energy gamma or X-rays as well as high energy gammas. The CN Series offers an effective energy range response of 3 keV to above 10 MeV. This compares to the CP Series energy response of 40 keV to 10 MeV. This improvement in response is made possible due to an aluminum end-cap with a beryllium entrance window on a detector constructed from N-type germanium material. An added bonus for these detectors is neutron damage resistance inherent to N-type germanium crystals.

CP Series P-type Germanium Detectors

Spectroscopy grade gamma detectors produced from high-purity P-type germanium has become the defecto standart. The primary reason is because P-type material has historyically been produced with higher yields than N-type material thus offering a greater variety in selection and lower costs. The identifying characteristic of these detectors is an effective gamma energy response range of 40 keV to 10 MeV. These detectors are relatively rugged with a totally enclosed aluminum end-cap, can be temperature cycled, are readily available in a variety of efficiences and resolution categories, and are the most economical of the high-purity germanium series.

Uniline Cryostat Preamplifier

All of Tennelec’s high-purity germanium detectors contain state-of-the-art charge sensitive, cooled FET preamplifiers. The preamplifier and high-voltage fitler network are encapsulated in the Uniline cryostat shroud. A temperature sensing circuit monitors the detector element and protects against warm-up damage by disabling the high-voltage. LEDs provide indications for high temperature and high count rate conditions. An exclusive cable pack insures compatibility with other manufacturers amplifiers yet eliminates the need for seperate signal and test pulser cables when used with a Tennelec amplifier.
