Final design and first use of in-situ measuring apparatus for measurement of permanent magnet resiliency in CEBAF’s radiation environment

Key Points

To design and implement a measuring apparatus for assessing the resiliency of permanent magnets in a radiation setting.
Developed a mobile measuring system for in-situ use
Established protocols for efficient measurement in adverse conditions
Ensured system functionality despite potential component failures
Initial tests successfully measured permanent magnets in situ
Mobile system operated effectively under CEBAF's radiation conditions
Protocols allowed for speedy evaluations of samples even with challenges

Abstract

In this work we outline the final design and initial measurement lessons for the holders and measuring apparatus of the permanent magnet resiliency experiment which is a part of the FFA@CEBAF proposed upgrade. The experiment will expose permanent magnets to the radiation environment of CEBAF. Due to safety regulations we need to measure the magnets in the tunnel without bringing them out, so we designed a mobile measuring system as well as a series of protocols to allow us to speedily measure these samples even under adverse conditions. We also designed our system to be capable of taking measurements even with component failures.
