The Evolutive Stellarator of Lorraine, ESTELL, aims at exploring the effectiveness of quasi-axial symmetry in a compact (R/a = 5 with R = 1.4m) stellarator. In order to manufacture and operate the device at a moderate level of technological difficulty with a rather low budget (12M€ needed for the construction), a simple coil design has been proposed resulting in a 2-period stellarator with low rotational transform ι ~0.2 able to confine = 0.5% plasmas, while keeping enough space between the…
