May 21, 2020: Canadian cosmic-ray muon pioneer CRM Geotomography launches as Ideon Technologies Inc.

CRM GeoTomography Technologies reduces cost and waste with new 3D insights of subsurface density.

Case Studies


As a rule of thumb, muon geotomography can be used in any application with meter-sized structures that have density contrasts larger than 0.1 – 0.2 grams per cubic centimeter (i.e., density contrast greater than about 1/10 the density of water). CRM has done work in applying this technology to

  • geophysical surveys for near and in-mine mineral exploration, to search for extensions to existing ore bodies (brownfield exploration)
    • CRM is also developing a miniaturized system for use in geophysical surveys away from existing mines (greenfield exploration)
  • air void identification and monitoring for block caving operations
  • oil reservoir monitoring in steam assisted gravity drainage (SAGD) operations
  • non-intrusive (passive) monitoring and interrogation of storage casks at nuclear waste storage facilities
  • inspection of cultural structures such as dams
  • monitoring underground and surface water levels, as well as snow pack depths

CRM's powerful simulation and analysis software allows us to quickly model scenarios of interest, to understand how muon geotomography can be used in new applications.

About Us

  • CRM GeoTomography Technologies, Inc. (CRM) is a geophysical services and sensor manufacturing company, specializing in a novel new technology known as “muon tomography”. Using sophisticated sensors to map the intensity of cosmic ray muons underground, CRM is able to construct detailed 3D density profiles of the ground above the sensors. CRM has proven the technology in a number of published field trials (see Case Studies above) as well as in other confidential projects with leading mining companies. We are also leading the way in developing muon geotomography for other applications, including geotechnical monitoring, SAG-D oil reservoir monitoring, and homeland security.

    CRM is a privately owned company spun-off from Advanced Applied Physics Solutions Inc. (AAPS, now TRIUMF Innovations), a nationally designated Centre of Excellence for Commercialization and Research established at TRIUMF, Canada's national laboratory for particle and nuclear physics and accelerator-based science. CRM is based in Vancouver, BC, Canada.

    CRM’s initial proof-of-principle muon geotomography technology was developed by AAPS in collaboration with University of British Columbia (UBC) professor Douglas Bryman, UBC’s Geophysical Inversion Facility, the Geological Survey of Canada, and NVI-Breakwater Resources (now Nyrstar).

    CRM’s advanced second-generation muon detectors have been developed with the financial support of Western Economic Diversification Canada, proven in field trials, and are now being commercially deployed by CRM to help mining companies reduce the cost and increase the effectiveness of near-mine mineral exploration. Funded projects from mining companies (under non-disclosure agreements) have contributed significantly to advances in the application of muon tomography.

    CRM gratefully acknowledges the ongoing financial support of the National Research Council of Canada (NRC) and all those that we work with to deliver the benefits of this new geophysical technique.
