I thought the trend mentioned was toward smaller, yet hotter plasmoids?

My reasoning is based on having to put 100 kJ energy into the plasmoid each shot. It may be hotter, but if it’s smaller, then less fuel gets burned. (unless smaller implies denser also??)
But I realize that since the machine hasn’t yet been optimized for boron, it’s a bit early to speculate.
