Accelerator plasma-target-based fusion neutron source

A description of stress driven bubble growth of helium implanted tungsten

“…In support of the HAPL project [4], the IEC facility at UW-Madison has investigated low energy helium implantation in tungsten [13,14] (IEC: inertial electrostatic confinement [30]). Formation of oversized surface bubbles along with drastic surface morphology changes were observed [14] when tungsten was exposed to a helium plasma with energies less than 60 keV and temperatures between 1000 and 1450 K.

Effect of Positive Polarity in an Inertial Electrostatic Confinement Fusion Device: Electron Confinement, X-ray Production, and Radiography

“…Finally, the beambeam or beam-background collision initiates the fusion process as a result of which neutrons are produced 7,9,10 . Since the development of the very first IECF device 11,12 , the researchers carried out geometrical and technical modification of the device in order to increase the neutron yield [13][14][15][16][17][18] , over the years. Recently, our team of researchers at CPP-IPR have a) Also at:Homi Bhabha National Institute, Anushaktinagar, Mumbai, Maharashtra, 400094, India; Email:smruti@cppipr.res.in carried out experiments in the cylindrical IECF device with some success in neutron production and its application in explosive detection [19][20][21][22][23] .…”

A study on neutron emission from a cylindrical inertial electrostatic confinement device

“…For increasing the amount of neutron flux and NPR following the IEC fusion scheme, the suitable modification was made in the designing and operating methodologies that resulted in the development of devices such as spherically convergent beam focus (SCBF), radially convergent beam focus (RCBF), spherically convergent ion focus (SCIF). The SCIF device at Wisconsin University achieved a higher range of fusion reaction rates up to 10 8 n/s for D-D fuel and 10 10 n/s using D-T fuel [12,13]. The SCBF device at TITECH developed a scheme for accelerating ions which are generated between electrodes by a glow discharge, towards the spherical center and giving rise to fusion reactions.…”
