A Herschel stopper is a method of cleanly suppressing a Herschel signal with an asynchronous boat-bit, discovered by Dean Hickerson in November 1996. In the infobox pattern, a ghost Herschel marks the location of output signal if the boat-bit is not present. The first Herschel travels through the conduit unaffected, but after the glider produces a boat-bit, the next Herschel collides with the boat and the two are mutually annihilated without affecting any of the nearby catalysts. Other boat-bit locations that allow for clean suppression of a Herschel are also known.
In the original report, Dean Hickerson demonstrated how the Herschel stopper can be inserted in a chain of Fx77, F117 and L112 conduits so as to construct adjustable pulse-dividing Herschel tracks.[1]
The term "Herschel stopper" is also occasionally used to refer to any mechanism that cleanly suppresses a Herschel. These are usually stable conduits that allow the Herschel's first natural glider to escape, so they are more commonly classified as converters. See SW-2.
