  1. Canadian Participation in EXO David Sinclair Carleton University

  2. The Rationale • The demonstration by SNO/Super-K /KamLand of neutrino oscillations points to double beta decay as a next critical direction for physics • Canadian groups have lot of expertise in the technical challenges of these experiments • Canada is committed to a programme of deep underground physics

  3. The Interested Groups • UBC – Doug Bryman • U. Montreal – George Azuelos, Claude Leroy, Jean_Pierre Martin,Louis-Andre Hamel, Viktor Zacek • Laurentian – Jacques Farine, possibly others • Guelph – Jimmy Law, Jagam, Possibly others • Carleton – Alain Bellerive, Madhu Dixit, Cliff Hargrove, David Sinclair

  4. Other Canadian Activity in Double beta decay • A group at Queen’s will work with the Majorana collaboration on Ge detectors. • There may be common facilities developed (eg low background counting) but the individuals will collaborate on only one project.

  5. Laurentian Plans • Jacques sends his regrets. He was not able to get a visa to travel to the US. • Jacques did his thesis on NUMU • He leads the SNO low energy background group • He wishes to study Rn and Kr removal from Xe

  6. Guelph • Participants in SNO • Would work on establishment of a low background Ge counting facility for materials studies and on radon reduction • Search for a senior professorship

  7. Carleton Participation • Group Background • OPAL Vertex chamber, Z chamber • First TPC used in an experiment • SNO water purification/assay systems • SNO analysis • Resources • Engineering • Workshop experienced in HEP detector construction • Computer farm

  8. Carleton Participants • Alain Bellerive – SNO, OPAL, CLEO • Madhu Dixit – TPC for NLC, OPAL • Cliff Hargrove – SNO, OPAL, • David Sinclair – SNO, Low energy nuclear

  9. Possible Carleton Programme • Investigation into Xe detector options • Study possible advantages of electroluminescence • Look at Micromegas, GEM applications in Xe • Detector simulations • Radioactivity studies (LAAPD’s) • Could provide engineering/fabrication assistance for the prototype programme • Expect to look for RA in near future
