4. Scope of work for the Cryoplant software development
Gathering information for software development - Complete
Preliminary software development – First draft complete
Bench testing – In Progress
Final software development – will be pre-released for commissioning
On-site adjustment during commissioning – Final released to OPS
This same software code is currently successfully running cryogenic plants following facilities:
Jefferson Lab CEBAF – (CHL2)
Oak Ridge National Lab – (SNS)
NASA Houston – (Johnson Space Center)
Michigan State University – (FRIB)
Brookhaven National Lab - (RHIC)*
* Process improvement – upgrade to “Ganni Cycle”
