Hi,
Anyone knows about any work or reference on Z-pinch plasma and their best achieved x-ray conversion efficiency?
Many thanks,
Rad
I'm going to assume you just want broadband Planckian x-rays...
It is about 10-15% and is just a function of Z-pinch current, so just add more capacitors :-) and you will get more X-ray output, it is a linear relationship, see Matzen, 1997 fig 2.
Here are a couple of references on x-ray CE for Zs (chap 8 or Haines, 2011)
On the Z machine(Sandia), 20MA, 20TW , 11.4 MJ it was about 15% or 1.8 MJ (see Cuneo, 2006), at 19 MA it was 2MJ (Stygar, 2004) reported, they varied many parameters,and wanted good symmetry. And 1.43 MJ with W arrays in Mazarakis, 2009. Coverdale, 2002 did a study on the optimal wire array.
Ampleford, 2014 reviews the physics in other non-Planckian sources on Z.
Hope this helps!
Imperial College has many people in the middle of z-pinch research, e.g., Jerry Chittenden, Simon Bland and Sasha Lebedev. They can help you focus your question more tightly, and point out other efforts at lower peak currents than the almost uniquely high values from Z at Sandia. You might find some of the previous work I summarized in 1988 helpful as well.
