Description

An AC current transformer (ACCT) is among the most robust non‑interceptive diagnostic tools for real‑time beam monitoring during beam delivery. At TRIUMF, ACCTs are installed in major beamlines, enabling continuous measurements of beam intensity without disrupting beam transport. This work evaluates the performance and operational characteristics of ACCTs used on the facility’s primary accelerator drivers: the electron linac (e‑linac) and the cyclotron. The measured ACCT noise level is on the order of microamperes. Building on this stability, the integration of online ACCT measurements into the Machine Protection System (MPS) is discussed to enable safe and reliable high‑power operation.
