Abstract
A passive annihilator comprising an annihilator element in the form of a spiral located at the end of a path of propagate elements whereby bubbles, entering the spiral element in response to the rotating in-plane magnetic field, will follow the spiral path to its center, and any subsequent bubbles, in a stream of bubbles, entering the spiral will help hold the prior bubble captive in the spiral. The final bubble in a bubble stream under high magnetic bias conditions will be annihilated near the spiral center while the final bubble under low magnetic bias conditions will circulate in response to the in-plane rotating field indefinitely in the spiral, but is not free to escape, and will be annihilated by the entry of new bubbles from a subsequent bubble stream.
