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.

Successful ignition in NIF will require targets that meet stringent standards as to symmetry, composition, and dimensions. We describe here the current understanding of specifications for baseline indirect drive targets of each of the three types of ablators: beryllium, polyimide, and plasma polymer. These specifications include the range of values for all targets of each group, and the variation in value allowed in a specific target of that group. They cover all of the components which make up a target, and which are critical to an implosion: the hohlraum and its components — windows, capsule support foil and gas fill — and the shell and its DT ice layer. These specifications are preliminary and incomplete; they will necessarily evolve with design details and with increasing understanding of target dynamics. They are compiled here as a reference for the ICF community and a basis on which to plan future work: to fill in the gaps and to develop thenecessary characterization techniques. Future work will also include the requirements for direct drive targets.
