In the low-aspect-ratio tokamak regime, a lower q(a) regime (i.e. q(a) {le}5, A = R/a {approx} 1.5) has been explored in CDX-U. Using a relatively low toroidal magnetic field, plasma discharges with I{sub p} {le}53 kA, and q(a) {ge} 4 [qcyl(a) {ge}1] have been obtained. Low q(a), ohmic plasmas in CDX-U show stronger MHD activity as the edge safety factor is reduced. Those MHD modes appear to reduce the current ramp-up rate and, at present, limit the access to even lower q(a) regimes.
