초록

TRIUMF, Canada's particle accelerator centre, is constructing a new high-power ISOL (Isotope Separation On-Line) facility called ARIEL (Advanced Rare IsotopE Laboratory). Thick porous targets will be bombarded with up to 48 kW of 480 MeV protons from TRIUMF's cyclotron, or up to 100 kW of 30 MeV electrons from a new e-linac, to produce short-lived radioisotopes for a variety of applications, including nuclear astrophysics, fundamental nuclear structure and nuclear medicine. For efficient release of radioisotopes, the targets are heated to temperatures approaching 2000 ℃, and are exposed to GSv/h level radiation fields resulting from intended fissions and spallations. Due to these conditions, the operational life for each target is only about five weeks, calling for frequent remote target exchanges to limit downtime. A few days after irradiation, the targets have a residual radiation field producing a dose rate on the order of 10 Sv/h at 1 m, requiring several years of decay prior to shipment to a national disposal facility. TRIUMF is installing new remote handling infrastructure dedicated to ARIEL, including hot cells and a remote handling crane. The system design applies learnings from multiple existing facilities, including CERN-ISOLDE, GANIL-SPIRAL II as well as TRIUMF's ISAC (Isotope Separator and ACcelerator).

과제정보

TRIUMF receives federal funding via a contribution agreement with the National Research Council of Canada. ARIEL is funded by the Canada Foundation for Innovation (CFI), and the grant numbers are: 33351, 20630, 36468, and 30897, the Provinces of AB, BC, MA, ON, QC, and TRIUMF. The authors wish to thank numerous groups inside and outside of TRIUMF who have contributed to this work. This includes current TRIUMF physics, engineering, and technical staff who are supporting the project, external reviewers from multiple laboratories including FRIB, ORNL, and CERN ISOLDE, as well as many retired or departed TRIUMF staff who have invested their careers into the development of the incumbent ISAC facility, on which ARIEL is largely based. Sincere thanks must also be given to TRIUMF's industrial colleagues and suppliers, including REEL-COH, ROBATEL Industries, Getinge La Calhène, and Sovis Saint-Gobain.
