Germanium Detectors Brochure

Product catalog summary

Company Overview
Canberra Industries is a leading manufacturer of nuclear radiation detection and analysis systems, with facilities in the U.S. and Europe. The company provides a wide range of detectors, including Ge detectors, PIPS detectors, and Si(Li) X-ray Spectrometers, along with various shields and accessories.

Germanium Detectors
Germanium detectors are semiconductor diodes with a P-I-N structure, sensitive to ionizing radiation like X-rays and gamma rays. They require cooling, typically with liquid nitrogen, to reduce thermal noise. Canberra offers a variety of detector types using both p-type and n-type germanium, with different contact technologies to suit various applications.

Cryostat Types
Canberra manufactures cryostats in flanged and slimline styles, suitable for diverse applications. Special cryostats include low background systems, multi-element detector telescopes, and electrically cooled detectors.

Preamplifiers
Two main types of preamplifiers are used with Ge detectors: charge sensitive preamplifiers with RC feedback or pulsed charge restoration. Pulsed-optical reset preamplifiers are preferred for low energy detectors, while transistor reset preamps are used for high energy, high rate systems.

Sales and Service
Canberra provides worldwide sales and service, with offices in multiple countries including Australia, Belgium, Canada, and the United Kingdom.

The energy rate limit can be increased very substantially by choos- ing a lower value feedback resistor with, of course, an accompa-nying increase in noise. Actual performance data on a typicaldetector is given below: There are only two basic types of preamplifiers in use on Gedetectors. These are charge sensitive preamplifiers that employeither dynamic charge restoration (RC feedback) or pulsed charge restoration (Pulsed optical or Transistor reset) methods todischarge the integrator. The following figure illustrates the en-ergy rate limitation of dc coupled RC feedback preamps. This is afunction...
