Awe T, McBride R, Jennings C, Lamppa D, Martin M, Rovang D, et al.
Phys Rev Lett
. 2014 Jan;
111(23):235005.
PMID: 24476283
Novel experimental data are reported that reveal helical instability formation on imploding z-pinch liners that are premagnetized with an axial field. Such instabilities differ dramatically from the mostly azimuthally symmetric...

Rev Sci Instrum
. 2013 Jul;
84(6):063504.
PMID: 23822342
Tests are ongoing to conduct ~20 MA z-pinch implosions on the Z accelerator at Sandia National Laboratory using Ar, Kr, and D2 gas puffs as the imploding loads. The relatively...

Phys Rev Lett
. 2008 Mar;
100(10):105003.
PMID: 18352197
Axially localized NaF dopants are coated onto Al cylindrical wire arrays in order to act as spectroscopic tracers in the stagnated z-pinch plasma. Non-local-thermodynamic-equilibrium kinetic models fit to Na K-shell...

Jones B, Deeney C, McKenney J, Garasi C, Mehlhorn T, Robinson A, et al.
Phys Rev Lett
. 2005 Dec;
95(22):225001.
PMID: 16384228
Three-dimensional perturbations have been seeded in wire-array z pinches by etching 15 microm diameter aluminum wires to introduce 20% modulations in radius with a controlled axial wavelength. These perturbations seed...

Phys Rev E Stat Nonlin Soft Matter Phys
. 2005 Oct;
72(2 Pt 2):026404.
PMID: 16196715
We have developed wire-array z -pinch scaling relations for plasma-physics and inertial-confinement-fusion (ICF) experiments. The relations can be applied to the design of z -pinch accelerators for high-fusion-yield (approximately 0.4...

X-ray emission from z pinches at 10 7 A: current scaling, gap closure, and shot-to-shot fluctuations
Stygar W, Ives H, Fehl D, Cuneo M, Mazarakis M, Bailey J, et al.
Phys Rev E Stat Nonlin Soft Matter Phys
. 2004 Jun;
69(4 Pt 2):046403.
PMID: 15169102
We have measured the x-ray power and energy radiated by a tungsten-wire-array z pinch as a function of the peak pinch current and the width of the anode-cathode gap at...

. 1994 Mar;
94(3):287-92.
PMID: 8120293
Objective: Previous studies based on 24-hour dietary recall data have shown that smokers tend to consume less healthful diets than nonsmokers. We tested this hypothesis using data from food frequency...

PMID: 8361508
Background: The prospective payment system, under which diagnosis-related groups (DRGs) are used to reimburse hospitals for the care of Medicare patients, replaced the fee-for-service method of payment in Rhode Island...
