• Target eLog - Operators, check this twice a shift to ensure screenshots are current!
• Target Troubleshooting Procedures
• TE Measurement Table
• Target Material Summary

Training Materials

Training for g2p target operators will consist of a brief online quiz on the topics covered here on the Wiki, followed by a practical course when the target is installed and running in the hall. The primer is also available as a PDF: File:G2p target primer.pdf.

• Practical Primer on the UVa Target
• Polarization Display Panel (PDP) Overview
• Target Operator Duties
• Target Training Slides

Take the quiz after you've read the above primer closely, and taken a look at the two others as well:

• Online Target Operator Quiz
  • List of Certified Target Operators

Operational Procedures

• PDP_Restart_Procedure
• Target Movement Procedure
• New Baseline Procedure
• Thermal Equilibrium Measurement Procedure
• Prepare Frig for Polarization
• Anneal Procedure
• Target Replacement Procedure (Experts only)
• Magnet Energization Procedure (Experts only)
