Sweepnik's Success
As
well as its speed, Sweepnik offered many advantages
over other track-measuring systems. The high signal-to-noise
ratio of the photomultiplier measurements meant it could
measure very faint tracks. Points on the tracks could
be recorded very accurately, and the system could be
produced relatively cheaply.
In
November 1969 Frisch and two others from the Cavendish
team set up Laser Scan Limited, a company to manufacture
the Sweepnik system. The system was shown off at the
International Conference on Nuclear Measuring Techniques
the following years, and by 1972 Sweepnik's had been
sold to the universities in Helsinki and Honolulu.
