Description

Since inception, the cryogenic system at Spallation Neutron Source (SNS) has been using a softioc-based alarm handler. It remained in place until the migration of all system alarms to the Best Ever Alarm System Toolkit (BEAST) in 2024. Although other SNS systems have migrated to BEAST, the cryogenic system could not transition to BEAST due to critical operational requirements. However, the addition of seven new cryomodules during the SNS Proton Power Upgrade (PPU) project necessitated the move from the softioc-based alarm handler to BEAST. Migration constraints, challenges, and implementation are discussed.
