“…An option of cryogenically cooled Al magnets has been considered which may be an alternative solution to superconductors if the necessary neutron shielding is provided. Wilson et al [25] extend the work of Hender [23], to propose a VNS (now termed a Component Test Facility, CTF) with A ~1.6, designed to consume < 1 kg of tritium per year and specifically to aid the fast-track approach to Fusion Power by testing components and materials. The device has R ~0.75m, I p ~ 8MA, B T ~ 2.8T, H~1.3, P NBI ~ 60MW, and yields P fus ~50 MW.…”

“…Several options of a Fusion Neutron Source have been studied during the last decade. They include the UKAEA Volumetric Neutron Source (VNS) [23], CCFE Component Test Facility (CTF) [24,25], Oak Ridge CTF [26], University of Texas CFNS [27] and TSUK/Kurchatov Institute Super Compact Fusion Neutron Source (SCFNS) [28,29]. Their main features and feasibility are analyzed and are discussed in this paper.…”

“…We compare options for a steady-state Compact Fusion Neutron Source based on a small or medium-size Spherical Tokamak with aspect ratio R/a = 1.6 -2.0. The most advanced design concepts, are medium-size STs with R~0.7-0.8m, based on VNS and CTF concepts developed at UKAEA, Culham Laboratory [23][24][25]. A pioneering paper by Stambaugh et al [30] set out many relevant scalings, and developed the concept that small pilot plants with R ~0.5m can lead to production plants by merely scaling the size.…”

“…Hence they require a worthy but ambitious and costly advance in performance. We also consider as an option both a bigger device, like STEP [12] and US CTF proposals [26] and other proposals for a smaller device with R ~ 0.5m [23,30]. The main parameters are compared in Table 1.…”

The use of fusion devices as powerful neutron sources has been discussed for decades. Whereas the successful route to a commercial fusion power reactor demands steady state stable operation combined with the high efficiency required to make electricity production economic, the alternative approach to advancing the use of fusion is free of many of complications connected with the requirements for economic power generation and uses the already achieved knowledge of Fusion physics and developed Fusion technologies. Fusion for Neutrons (F4N), has now been re-visited, inspired by recent progress achieved on comparably compact fusion devices, based on the Spherical Tokamak (ST) concept. Freed from the requirement to produce much more electricity than used to drive it, a fusion neutron source could be efficiently used for many commercial applications, and also to support the goal of producing energy by nuclear power. The possibility to use a small or medium size ST as a powerful or intense steady-state fusion neutron source (FNS) is discussed in this paper in comparison with the use of traditional high aspect ratio tokamaks. An overview of various conceptual designs of compact fusion neutron sources based on the ST concept is given and they are compared with a recently proposed Super Compact Fusion Neutron Source (SCFNS), with major radius as low as 0.5 metres but still able to produce several MW of neutrons in a steady-state regime.
