Nuclear Science Experiments for Teaching Laboratories
With over 45 years of experience in the nuclear measurements industry, CANBERRA is uniquely qualified to provide you with the tools for creating informative and highly productive laboratory experiences for your students. The Nuclear Science Experiments with Digital Electronics Laboratory Manual offers turn-key solutions to set up and/or refurbish your nuclear physics teaching facility with the newest and cutting-edge digital technology.
CANBERRA has developed a set of 12 experiments, focusing on various aspects of gamma-ray detection and analysis, which provides an understanding of basic to more complex nuclear physics principles. All of these experiments can be executed completely with the CANBERRA instrumentation and specialized ancillary equipment offered in the two Lab Kits described on the left. However, please note that most of the recommended radioactive sources must be obtained separately and are readily available from educational source providers if not already owned.
The Laboratory Manual and kits greatly simplify the purchase of equipment and implementation of these experiments (plus other experiments of your own design). They can be used to create individual student workstations or a central demonstration station, depending on available space and budget. And, of course, lab expansion is just as simple as adding more kits as your needs dictate. The kits are included in our Fuel for Innovation Program to make them even more affordable and a great asset for your teaching or research laboratory.
A short decription of each experiment is below. Click the link above for the full manual with the complete experiments.
In this introduction to gamma-ray detection, students will identify photoelectric effect, Compton scattering, and pair production in a spectrum and perform an energy calibration using known reference sources.
Students will perform a series of background and gamma-ray measurements with a NaI detector and apply statistical principles to these measurements.
Students will measure the effective attenuation of a set of materials with varying densities and photon absorption cross sections.
Using the Compton Scattering table developed specially for this exercise, the principle of Compton scattering and the dependence on angular variation is demonstrated.
Students calculate the half-life of a short-lived nuclide using multi-channel scaling acquisition.
Using the built-in Digital Signal Oscilloscope feature of the LYNX MCA, students observe the effects of changing signal processing parameters using several different acquisition modes.
Semiconductor gamma-ray detection is introduced and students compare HPGe resolution to NaI detector resolution.
Using both a NaI detector and an HPGe detector, the concept of detection efficiency is explored.
Counting with multiple detectors correlated in time can yield incredible information about fundamental nuclear structures. In this experiment, students learn these techniques by acquiring and interpreting time-stamped list mode data for synchronized detectors.
By using coincidence counting techniques and the Angular Correlation table, students explore the geometrical behavior of positron annihilation events.
Mathematical modeling is increasingly used instead of source based efficiency calibration for improvement in cost, flexibility, and safety. In this experiment, students generate efficiency calibrations using Canberra's LabSOCS efficiency calibration software and compare against traditional source based calibrations.
Students observe true coincidence summing and quantify the effect on observed count rate using LabSOCS mathematical efficiency software.
