==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: [[Image:G2p target primer.pdf]].

*[[Practical Primer on the UVa Target]]
*[[Polarization Display Panel (PDP) Overview]]
*[[Target Operator Duties]]
*[https://userweb.jlab.org/~jmaxwell/g2p/g2p_target_training.pdf Target Training Slides]

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