At the Madison Conference it was reported [1] that a periodic caulked-cusp field is effective in the suppression of toroidal drift of a toroidal theta-pinch plasma as well as in its stabilization. Here, it is demonstrated that a theta-pinch plasma produced at low pressure regime is confined stably for a longer time of around 80μs in the caulked-cusp torus (abbreviated to CCT) field, using the second machine CCT-II which is larger and fatter with a fewer rings than the first one CCT-I used at the time of the Madison Conference. Energy distribution of particles of the theta-pinch plasma is investigated by means of energy analysis of fast neutral particles emitted from the confined plasma. And it is found that the plasma confinement time is limited to be 80μs by the decrease of the confining field strength due to the decay of the crowbarring current and the induced ring-current, while the density decay time is estimated to be 120μs. Those are confirmed also with the measurements of time variation of spectral lines H_β (D_β) and the continuum due to bremsstrahlung.
