	The Advanced Rare Isotope Laboratory (ARIEL) is TRIUMF's flagship project to create isotopes for science, medicine and business. ARIEL will triple TRIUMF's rare isotope beam capability, enabling more and new experiments in materials science, nuclear physics, nuclear astrophysics, and fundamental symmetries, as well as the development of new isotopes for the life sciences. Beams from ARIEL's new 35 MeV, 100kW electron linear accelerator and from TRIUMF's original 500 MeV cyclotron will enable breakthrough experiments with the laboratory's suite of world-class experiments at the Isotope Separator and Accelerator (ISAC) facility. This invited talk will present an overview of TRIUMF, the ARIEL project, and the exciting science they enable.

THPAL121	The Operational Experience of E-Linac Cryogenic System at TRIUMF	3928
	R.R. Nagimov, Y. Bylinskii, D. Kishi, S.R. Koscielniak, A.N. Koveshnikov, R.E. Laxdal, D. Yosifov TRIUMF, Vancouver, Canada
	Funding: ARIEL is funded by CFI, the Provinces of AB, BC, MA, ON, QC, and TRIUMF. TRIUMF receives federal funding via a contribution agreement with the National Research Council of Canada. The new Advanced Rare IsotopE Laboratory (ARIEL) is a major expansion of the Rare Isotope Beams (RIB) facility at TRIUMF. Superconducting radio-frequency (SRF) cavities cooled down to 2 K are the key part of ARIEL electron linear accelerator (e-linac). Design of the cryogenic system was bound to follow both phased project schedule and existing building infrastructure. Due to the scheduling of commissioning and R&D activities of ARIEL project, high availability requirements were set for e-linac cryogenic system during its commissioning stage. Various upgrades were introduced during system commissioning in order to improve overall availability and reliability of the system. This paper presents the details of operational experience, commissioning activities and continuous improvement of various operational aspects of e-linac cryogenic system.

THPML025	Operation of an RF Modulated Thermionic Electron Source at TRIUMF	4705
	F. Ames, K. Fong, B. Humphries, S.R. Koscielniak, A. Laxdal, Y. Ma, T. Planche, S. Saminathan, E. Thoeng TRIUMF, Vancouver, Canada
	ARIEL (Advanced Rare IsotopE Laboratory) at TRIUMF will use a high-power electron beam to produce radioactive ion beams via photo-fission. The system has been designed to provide up to 10 mA of electrons at 30 MeV. The electron source delivers electron bunches with charge up to 16 pC at a repetition frequency of 650 MHz at 300 keV. The main components of the source are a gridded dispenser cathode (CPI - Y845) in an SF6 filled vessel and an in-air HV power supply. The beam is bunched by applying DC and RF fields to the grid. A macro pulse structure can be applied by additional low frequency modulation of the RF signal. This allows adjusting the average beam current by changing the duty factor of the macro pulsing. Unique features of the gun are its cathode/anode geometry to reduce field emission, and transmission of RF modulation via a dielectric (ceramic) waveguide through the SF6. The source has been installed and fully commissioned to a beam power up to 1 KW and tests with accelerated beams have been performed. Measurements of the beam properties and results from the commissioning and operational experiences of the source will be presented.

THPML077	Status of the Machine Protection System for ARIEL e-linac	4829
	M. Alcorta, D. Dale, H. Hui, S.R. Koscielniak, K. Langton, K. LeBlanc, M. Rowe TRIUMF, Vancouver, Canada
	The Advanced Rare Isotope & Electron Linac (ARIEL) facility at TRIUMF consists of an electron linear accelerator (e-linac) capable of currents up to 10 mA at an energy of 30 MeV, giving a total available beam power of 300 kW. In addition, the e-linac can be run in pulsed operation down to beam pulses of 5 μs, up to CW. A Machine Protection System (MPS) is required to protect the accelerator from hazardous beam spills and must turn off the electron gun within 10 μs of detection. The MPS consists of two types of beam loss monitors, a front-end beam loss monitor board developed at TRIUMF, and EPICS-based controls to establish operating modes. A trip time of 10 μs has been demonstrated, along with a 10⁶ dynamic range and sensitivity down to 100 pA. This paper is focused on the current status of the beam loss monitor detection system.
