	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.

TUPPC101	Scaling of EPICS edm Display Pages at ISAC	ISAC, controls, EPICS, factory	816
	R. Keitel TRIUMF, Canada's National Laboratory for Particle and Nuclear Physics, Vancouver, Canada
	The EPICS-based control system of the ISAC facility at TRIUMF uses the edm display editor / display manager to create and render the Operator interface displays. edm displays are expressed in pixel coordinates and edm does not scale the display page when a window is re-sized. A simple scheme was implemented to allow operators to switch page magnifications using a set of pre-selected scaling factors. Possible extensions of the scheme and its limitations will be discussed.

THPPC001	Overview of "The Scans" in the Central Control System of TRIUMF's 500 MeV Cyclotron	software, cyclotron, controls, hardware	1090
	J.J. Pon, K.S. Lee, M. Mouat, P.J. Yogendran TRIUMF, Canada's National Laboratory for Particle and Nuclear Physics, Vancouver, Canada B. Davison SFU, Burnaby, BC, Canada
	The Controls Group for TRIUMF's 500 MeV cyclotron developed, runs and maintains a software application known as The Scans whose purpose is to: a) log events, b) enunciate alarms and warnings, c) perform simple actions on the hardware, and d) provide software interlocks for machine protection. Since its inception more than 35 years ago, The Scans has increasingly become an essential part for the proper operation of the Cyclotron. This paper gives an overview of The Scans, its advantages and limitations, and desired improvements.

	In the pursuit of progressively more stable beam currents at TRIUMF's 500 MeV cyclotron there was a proposal to regulate the beam current split ratio for two primary beamlines with closed-loop feedback. Initial runs have shown promising results and have justified further efforts in that direction. This paper describes the software to provide the closed-loop feedback, and future developments.
