2. Additional studies, performed with multiple pellet injections, have extended the TJ-II operational regime well beyond limits previously achieved in this device using NBI heating and gas puff. In order to achieve best results, the plasma target electron density should to be in the range 1x10^1919 to 2.5x10^19 m^-3 and time separations between pellets should be close to energy confinement times, around 10 ms.
