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.

Magnetically sweeping the separatrix along the divertor plate is proposed to accommodate higher heat loads or to reduce the maximum armor/coating surface temperature for a given heat flux distribution. During the sweeping, each position on the divertor plate will experience periodic heat and particle flux variations. The magnitude of these variations with time will depend on the location as well as on the time shape of the sweeping wave. Consequently, the shape of the sweeping pulse and the sweeping frequency will determine the maximum surface temperature as well as the spatial distribution of the temperature along the sweeping distance. Sweeping is also expected to increase the lifetime due to reduction in both physical sputtering and chemical and radiation enhanced erosion for materials such as graphite or carbon composites.
