  • CSG objects can be represented by binary trees, where leaves represent primitives, and nodes represent operations. In this figure, the nodes are labeled ∩ for intersection, ∪ for union, and — for difference. Constructive solid geometry (CSG; formerly called computational binary solid

  • The utility of Auger radionuclides in therapy is believed to hinge on their photon-to-electron energy yield, or “p/e ratio” (Bernhardt et al., 2001). Since photons deposit most of their energy in healthy tissues away from small targets, their dose contribution is typically unwanted in Auger therapy. Therefore, a p/e ratio as low as possible is generally considered desirable. Rhodium-103 m (103mRh, T½ = 56.11 min) decays via isomeric transition to stable 103Rh, giving rise to the emission of Auger electrons (Fig. 1). The decay of 103mRh distinguishes itself by having a high Auger electron yield…

  • Based on expected values of heat flux in a power plant, a helium - cooled first wall and blanket can be designed w ith relatively simple transverse flow paths; more exotic flow schemes are not required.

  • In magnetic confinement fusion, a divertor is a device which extracts heat and ash from fusion plasmas by averting direct contact between the confined plasma and the main chamber wall (plasma-wall interactions). A magnetic divertor typically involves creating a separatrix-bounded magnetic topology using special magnetic coils. Particles and heat diffusing outward from the main plasma are diverted and follow the 'open' magnetic field lines to strike dedicated plasma-facing components.

  • Helium is an attractive coolant for fusion power plant applications due to its chemical inert ness ( resulting in safety and performance advantages), compatibility with other reactor materials, low neutron cross section, and high temperature capability to enable high thermo - dynamic efficiencies.
