Phase 1 of the Advanced Rare Isotope & Electron Linac (ARIEL) facility at TRIUMF is scheduled for completion in 2014. It will utilize an electron linear accelerator (eLinac) capable of currents up to 10mA and energy up to 75MeV. The eLinac will provide CW as well as pulsed beams with durations as short as 10uS. A Machine Protection System (MPS) will protect the accelerator and the associated beamline equipment from the nominal 500kW beam. Hazardous situations require the beam to be extinguished at the electron gun within 10uS of detection. Beam loss accounting is an additional requirement of the MPS. The MPS consists of an FPGA based controller module, Beam Loss Monitor VME modules developed by JLAB, and EPICS -based controls to establish and enforce beam operating modes. This paper describes the design, architecture, and implementation of the MPS.

The Advanced Rare Isotope & Electron Linac (ARIEL) facility at TRIUMF, scheduled for Phase 1 completion in 2014, will use a control system based on EPICS. Discrete subsystems within the accelerator, beamlines and conventional facilities have been clearly identified. Control system strategies for each identified subsystem have been developed, and components have been chosen to satisfy the unique requirements of each system. The ARIEL control system will encompass methodology already established in the TRIUMF ISAC & ISAC-II facilities in addition to adoption of a number of technologies previously unused at TRIUMF. The scope includes interface with other discrete subsystems such as cryogenics and power distribution, as well as complete subsystem controls packages.

Configuration Management for Beam Delivery at TRIUMF/ISAC

The ISAC facility at TRIUMF delivers simultaneous beams from different ion sources to multiple destinations. More beams will be added by the ARIEL facility which is presently under construction. To ensure co-ordination of beam delivery, beam path configuration management has been implemented. The process involves beam path selection, configuration setup and configuration monitoring. In addition save and restore of beam line device settings, scaling of beam optic devices for beam energy and mass, beam path specific operator displays, the ability to compare present and previous beam tunes, and alarm enunciation of device readings outside prescribed ranges are supported. Design factors, re-usability strategies, and results are described.
