|
The Advanced Rare Isotope Laboratory (ARIEL) project at TRIUMF requires a 50 MeV superconducting electron Linac consisting of five nine cell 1.3 GHz cavities divided into three cryomodules with one, two and two cavities in each module respectively. The cryomodule design utilizes a unique box cryomodule with a top-loading cold mass. LHe is distributed in parallel to each cryomodule at 4 K and at ~1.2 bar. Each cryomodule has a cryogenic insert on board that receives the 4 K liquid and produces 2 K liquid into a cavity phase separator. In the cryomodules the natural two-phase convection loops, i.e. siphon loop, are installed which supply 4 K liquid to thermal intercepts and return the vaporized liquid to the 4 K reservoir as a refrigerator load. The design of the cryomodule, the simulation results with Ansys Fluent and the results of the cold tests will be presented.

| THPLR023 | The ARIEL Radioactive Ion Beam Transport System | 891 |
|
||
| The Advanced Rare IsotopE Laboratory (ARIEL) is going to triple the radioactive ion beam (RIB) production at TRIUMF. The facility will enable multi-user capability in the Isotope Separation and ACceleration (ISAC) facility by delivering three RIBs simultaneously. Two new independent target stations will generate RIBs using a proton driver beam up to 50 kW from the 500 MeV cyclotron and an electron driver beam for photo-fission from the new superconducting e-linac in addition to the existing ISAC RIB production. The multi-user capability is enabled by a complex radioactive ion beam transport switchyard consisting entirely of electrostatic optics. This system includes two separation stages at medium and high resolution with the latter achieved by a mass separator designed for an operational resolving power of 20000 for a 3 micrometer transmitted emittance. Part of the system also includes an Electron Beam Ion Source (EBIS) charge breeder fed by a radio frequency cooler that allows the post-acceleration of heavy masses. Beam selection downstream of the EBIS is achieved by means of a Nier type separator. The facility is in a detailed design stage and some tests, procurements and partial installation are foreseen by the end of 2016. | ||
