'''1. ESR Capacity'''
 
 
 
ESR is a variable capacity machine producing 4.5K and 15K temperatures.
 
 
 
The two endpoints are approximately (1,500W at 4.5K and 0W 15K) or (800W at 4.5K and 1,200W at 15K).
 
 
 
The addition of the CHL-ESR transferline adds up to 2,000w at 4.5K with increased electrical power and LN2 costs at CHL.
 
 
 
 
 
 
 
'''2. Round table, initial impressions'''
 
 
 
Lively discussion of what we have been asked to do.
 
 
 
'''3. Start of brainstorming'''
 
 
 
How do we ''measure'' reliability? Metrics?
 
 
 
Standardize some of the definitions, terminology (reliability vs availability)
 
 
 
The goals of the team should be more tightly defined as we progress (staged goals?)
 
 
 
Do we care if something breaks when machine is not running? This needs better defining. Maybe individual groups care (for tracking) but it does not affect the machine. At present we do not track failures during the SAD periods.
 
 
 
Tools for data gathering. ''(Maybe Randy could demonstrate the Downtime Manager (DTM) next meeting for those that have not seen it?)''
 
 
 
Many of the components that make up the machine are running to their limits. Operational regimes and their effect on reliability appear to have not been widely considered.
 
 
 
The group (or designees) may have to look at historical data.
 
 
 
Steve Suhring et. al. looked at reliability during the 6GeV era, other teams/individuals have looked as well. Why haven't any long term recommendations been adopted? (were there any?)
 
 
 
''Return on investment'' of projects was discussed. Downtime costs $$. One should be able to justify the cost (money/time) of an upgrade by showing that it will save x dollars in the future.
 
 
 
== Action Items ==
 
 
 
Attendees will notify cryo of any changes to the plan and future meetings will be held as required.
