SUMMARY:3D-printed stellarators: Towards high-field ignition stellarat
 ors\, Plasma Theory Seminar\, Vicente Queral\, National Fusion Laborat
 ory\, CIEMAT\, Spain
DESCRIPTION:In the framework of magnetic fusion energy research\, toka
 maks (with plasma current) and stellarators (with negligible or low pl
 asma current) are two major types of toroidal fusion devices. The cons
 truction of stellarators by Additive Manufacturing combined with compo
 sites\, and the concept of a high-field ignition-capable stellarator (
 i-ASTER) are presented. Such additive manufacturing technique is imple
 mented in a tabletop stellarator (UST_2) and is planned for i-ASTER. U
 ST_2 is an advanced quasi-isodynamic stellarator equipped with 3D-prin
 ted and detachable monolithic supports for the coils\, having produced
  satisfactory e-beam experiments for validation. i-ASTER is a high mag
 netic field (B=10T on axis) and relatively small size (30 m3 plasma vo
 lume) stellarator design aimed at achieving ignition\, studying ignite
 d plasmas and advancing power extraction systems (e.g. lithium based).
  It is characterised by massive copper coils of variable cross-section
 \, detachable periods\, and a lithium wall/divertor.
