Spectral/target activity of short lived radio isotope in pulsed plasma accelerator.
Accelerated deuteron spectra from magnetic spectrometry and graphite bombardment by such deuterons were used to produce short-lived radionuclides in NX2 plasma focus. The experiments show one order of magnitude difference between the activity generated by these techniques. The average activity of NX2 is 5.2 kBq and the highest activity for the best shot is about 40 kBq.
Plasma Platform to Investigate Error Structure in the Electronic Components
This program was designed to introduce a plasma platform to examine the field programmable gate array (FPGA) of the link boards typically used at the CERN’s Large Hadron Collider (LHC). Pulsed plasma systems with accelerating gradient of 1 kV/<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> generate high-intensity, high-energy radiation beams. Single-event upset (SEU) is caused by radiation deposition in the FPGA. In FPGA, the SEU probability for 1-MeV protons and 10-keV X-rays are 0.1 and <inline-formula> <tex-math notation="LaTeX">$2 \times 10^{-9}$ </tex-math></inline-formula> particle<inline-formula> <tex-math notation="LaTeX">$^{-1}$ </tex-math></inline-formula>. The number of SEU induced in the Si by 1-MeV proton irradiation at 0.8-V bias computed from simulation in COMSOL Multiphysics was <inline-formula> <tex-math notation="LaTeX">$1.8 \times 10^{5}$ </tex-math></inline-formula>. Although more experimental research is needed to identify the underlying mechanisms, pulsed plasma is perceived as being a smart alternative to investigate the error structure in FPGA.
