What’s the most difficult question you’ve been asked as a maintenance instructor?
Blye Widmar
"Where are the prints?!"
This was the final question in an onslaught of verbal feedback, comments, and critiques I received from my students back in 2019. I had two years of instructor experience and was teaching a class that had been meticulously rehearsed in preparation for an accreditation visit. I knew the training material well and transferred that knowledge effectively enough for all the students to pass the class. As we wrapped up, I asked the students how they felt about my first big system-level class, and they did not hold back.
“Why was the exam from memory when we don’t work from memory in the plant?” “Why didn’t we refer to the vendor documents?” “Why didn’t we practice more on the mock-up?” And so on.

A novel diagnostic f or ion temperature and density is discussed. The diagnostic, based on the detection of the 24-MeV gamma photon from the D(d,γ)4He fusion reaction, appears feasible in reactor-oriented tokamaks. The use of an optimized differential neutron/gamma filter reduces this ratio from 107 at the plasma to ∼1 on the detector. Under these conditions, measurement of the plasma ion temperature and density of a thermonuclear plasma is possible by using a large, high-purity germanium detector as a spectrometer.
