已经采取了两个步骤来确定球马克的磁通吸收和驰豫特性是否允许直流供电的电极形成并维持稳定的球马克。在不改变球面的物理性质的情况下，形成时间从Alfven时间增加到撕裂时间，将同轴源功率从大约10GW降低到大约500 mW。在使用约50 mW的情况下，形成球痕，然后在恒定密度和磁场下保持1ms，比磁能衰减时间长得多。
Two steps have been taken towards determining if the flux absorption and relaxation properties of a spheromak will allow dc-powered electrodes to form and sustain a steady-state spheromak. Without changing the physical properties of the spheromak, the formation time was increased from an Alfven time to a tearing time, reducing the coaxial source power from approx.10 GW to approx.500 MW. With use of approx.50 MW, spheromaks were formed and then sustained at constant density and field for 1 ms, much longer than a magnetic energy decay time.
