GRIFFIN Collaboration

GRIFFIN - Gamma-Ray Infrastructure For Fundamental Investigations of Nuclei - is a state-of-the-art facility for decay spectroscopy with rare-isotope beams located at the TRIUMF-ISAC-I facility, Vancouver, Canada. An array of 16 high-purity germanium clover detectors coupled to a fully digital data acquisition system dramatically increases gamma-ray detection efficiency and data aquisition throughput over past experiments, while leveraging a powerful suite of ancillary detectors developed for its predecessor, the 8pi spectrometer.

The GRIFFIN infrastructure has been funded jointly by the Canada Foundation for Innovation, the British Columbia Knowledge Development Fund (BCKDF), the Ontario Ministry of Research and Innovation (ON-MRI), TRIUMF and the University of Guelph. TRIUMF receives federal funding via a contribution agreement through the National Research Council Canada (NRC). The ongoing maintenance and operation of the GRIFFIN facility is funded through a Natural Sciences and Engineering Research Council of Canada (NSERC) subatomic physics project grant.

Land Acknowledgement

The Gamma Ray Spectroscopy at ISAC team acknowledges that our work spans many Territories and Treaty areas and we are grateful for the traditional Knowledge Keepers and Elders who are with us today, those who have gone before us and the youth that inspire us. As an act of Reconciliation and gratitude to those whose territory we visit, reside and work on, and as recommended by the Truth and Reconciliation Commission’s (TRC) 94 Calls to Action, we recognize the land and the benefits it provides all of us.

17x efficiency

GRIFFIN is 17 times more efficient in gamma-ray singles (almost 300 times more efficiency for gamma-gamma coincidences) at 1 MeV, and around 40 times more efficient at 10 MeV, than its predacesor.

Massive Data

The GRIFFIN DAQ is capable of writing up to 200 TB of data to disk every week - allowing the exploration of rarer processes than ever before.

Physics on the Web

The GRIFFIN Toolkit is a suite of web apps built for designing, understanding and running experiments at GRIFFIN, all on the web. Check out our tools, or look under the hood - all GRIFFIN web projects are open source on GitHub.
