Overview
• Introduction to ISAC
• Past: Phase I – on-line testing
• one target module
• more target modules
• Present: Phase II – off line testing
• ISAC target life cycle
• Future: Phase III – remote connect &
disconnect

Documenting & Improving
• Target travel document
• Learn from failures
• Learn from success
• Standardized parts
• Dedicated target reliability engineer

Phase III
• Present: manual connect/disconnect
• Cool- down for one week after beam off
• Beam off during manual dis/re-connect
• Personnel dose
• Future: remote connect/disconnect
• No cool-down necessary
• Dis/Re-connect can be done while delivering
beam from the other station
• No dose to personnel

Summary
• Phase I => II
• Gain: ~ 9 days beam
availability and
improved reliability
• Phase II => III
• Gain: ~11 days
beam availability
and further improved
reliability
