We have newly developed flexible electronic paper using an easily‐controlled adhesive column spacer that forms cell gaps and improves the aperture ratio without using bead spacers. The reflectance of this new, flexible, full‐color prototype with low‐ power driving is 33%, its contrast is over 6, and it can display 262,144 colors.

The longitudinal confinement of a plasma in a pulsed multi-mirror fusion reactor is investigated. It is shown that the initial plasma energy W p per unit of reactor cross-section and the initial plasma temperature T o serve as similarity parameters. One-dimensional numerical calculations of plasma flow along the reactor axis were performed for various W p and T o and were used to determine the plasma gain function QE(W P , T o ). The region of maximum values of QE lies near T o = 5 keV for all W p . Plasma heating by a-particles becomes substantial for values of Q exceeding unity. At W p = 20 MJcm" 2 , QE calculated with plasma heating by a-particles exceeds QE as calculated without including such heating by a factor of five. If the mirror ratio is increased by enlarging the cross-section towards the reactor ends, Q is further increased by a factor of two. A value of QE = 1 is achieved at an initial plasma energy of W p « 5 MJ-cm" 2 , and QE = 10 is achieved for W p «12MJ-cm" 2 .
