QPS Individual System Test (QPS-IST) for the main circuits (dipole circuit as example)
Field Team in the tunnel:- switching on all QH Power Supplies;- waiting feedback for intervention;
LHC equipment to test:- 154 quench detectors;- 4x154 quench heaters;
PM Data storage (SDDS)
Logging DB
Trigger all quench detectors orre-trigger problematic ones
Office team
QPS-IST PM data Analysis
Objectives of “mass” Analysis:- read all PM-data, check completeness;- special QPS-dedicated analysis: charge and discharge voltages, time constants, quench detection levels and delays, etc...;- create output report;
Intervention instruction!

QPS-IST PM data Analysis
Objectives of Analysis- read all PM-data, check completeness;- special QPS-dedicated analysis: charge and discharge voltages, time constants, quench detection levels and delays, etc...;- create output report;- “bad heaters” detection;
- in 2008 HWC-campaign custom SDDS-library was used (ASCII);-since 2009 PM reading was switched to RADE SDDS-library (binary); Comments: reading is faster, but not checked yet in real HWC.
Manual alternative: Very powerful and reliable PM-browser (RADE), but analyzing one by one over 154 PM-files!!!

-Analysis takes 1-2 minute ;- It really depends on PM-data reading speed,and time for the Report

Snapshot Analysis for the main circuits
Originally it was developed as a minor modification of QPS-IST Analysis :
- Analysis part is simpler –> extracting just one signal from PM-file;- but much more PM data required, many steps in current loads;- and additional post processing which requires data from logging DB;
Finally, it worked very well. Two bad splices were found and confirmed.
Now new version of Snapshot Analysis Software is developing which supposedto be integrated to the HWC procedures:
- The snapshots will be triggered from HWC Sequencer, not manually anymore;- Analysis Software will be integrated with the PM Event Analyzer (RADE!!!)

600A Circuits: PCC.5 – QPS Semi-Automatic Analysis
- already integrated with PM Event Analyzer (RADE);- has been used in 2008 HWC campaign; - almost ready to be automatic: + PM Data check to be added; + Criteria need to be fixed;
