Centre for Molecular and Materials Science

The Centre for Molecular and Materials Science (CMMS) provides unique tools for Canadian and international scientists to better understand matter at the microscopic level. We provide intense spin-polarized beams of muons (µ⁺ or µ⁻) and lithium-8 (⁸Li), which are implanted into a material and characterized with novel magnetic resonance techniques known as µSR (muon spin rotation / relaxation / resonance) and βNMR (beta-detected nuclear magnetic resonance). µSR and βNMR can provide unique information about a wide range of materials (magnetic systems, superconductors, semiconductors, batteries and free radicals) that is unavailable with conventional spectroscopic methods.

The proposal submission deadline for the MMS-EEC is December 9^th, 2024. Request new experiment numbers by December 2^nd. The next meeting will take place on January 20^th&21^st, 2025.

Announcements:

As of 2019, TRIUMF CMMS will no longer charging academic researchers for liquid helium or other user fees.

The procedures for visiting scientists have been changed. Please contact I. McKenzie to request an invitation. Once you have received the invitation you must fill in your details on the Visitor App. Group leaders will be able to invite subordinates.
