Problem: Need inexpensive, portable, user-friendly tester for in-field validation of radiation sensor equipment operation.

Project Activity Scope (from Technical Overview Chart): Circuits and Devices through Controls and Measurements.

PNNL Solution:

  • Use DVD technology to enable adaptable "radiation source" testing
  • Develop compact, integrated tester with single button operation
  • Hardware design is independent of detector type
  • DVD's recorded with radiation source specific pulse streams allow rapid testing of multiple systems

Capabilities Employed to Meet Client Needs:

  • Conceptual design development; digital electronics for interface to commercial DVD drive and for DAC to create simulated signals from DVD output; analogue electronics to properly shape DVD output pulses to simulate radiation detector signals; embedded software for DVD control and user interface; mechanical design for user-friendly packaging; design and operation documentation.
