I'm impressed.

My reference to specialized components was an oblique way of bringing up the initiator, one of the hardest things to build, and you are exactly right about initiator timing being critical for pre and post detonation reasons. Also, you are correct in that the gun design cannot be made small on the same scale as an implosion design because the gun does not really compress the uranium, it just assembles a 'normal density' critical mass. It's an inefficient design from a 'use of nuclear materials' point of view. I believe (but I could be wrong) that both Uranium and Plutonium are cast in 'near net' shape and then machined. None of these is an insurmountable problem, just challenging in multiple different fields. I agree with you.

Here's a cool link, if you don't already have it...

I have taken to studying this type of nuclear physics area a lot over the years, both due to my (life long) geeky scientific curiosity, and my desire to be able to have educated guesses about proliferation like you are discussing here.

I just friended AdrienG back and look forward to reading you. Any friend of Malabar... It is my usual practice to friend anybody back unless casual inspection of their journal scares me, heh!

Best wishes...

You have an interesting journal, I'm going to lurk a while.

May I suggest for your reading pleasure...

I googled it and it looks very interesting... Thanks for the reference.

I really get a look at how important language is for social well being when I work with kids with language problems, that's for sure!

Have a great day.
