The ARIEL facility, currently under construction at TRIUMF, brings two new target stations and a new electron driver beam from ARIEL's e-linac to the TRIUMF facility. With these upgrades comes a suite of new technologies and new methodologies specific to the challenges posed by the ARIEL target station design. Several offline test stands, becoming increasingly integrated as the tests progress, have been designed and constructed. They will validate the new concepts and designs, and facilitate studies of particular aspects of the ARIEL design. The use of an electron driver beam necessitates a redesign of the typical ISOL target and target vessel geometry used with a proton driver beam. Increased air activation also imposes stringent requirements on the system for remotely coupling and decoupling the target vessel. In addition, the target vessel must be coupled to both the driver and RIB beam lines, unlike the case for a proton driver beam. ARIEL target stations will also deliver a large number of services through the target vessel, and the TRIUMF facility as a whole faces unique coupling and alignment challenges by inserting and removing parts of the target station vertically. Investigations into the performance and reliability of these enhancements are crucial to successful online operation and studies focusing on the main challenges are underway. The results from these ongoing tests will be presented with an emphasis on the unique features present in the ARIEL era.
