Abstract
An integrated tunnel junction dc SQUID cascade has been built and some of its operating characteristics measured. It is shown for the first time that good modulation can be achieved with a remote termination for the tunnel junction shunts. Response time of one of the SQUID´s in the cascade was measured to be better than 5 nanoseconds. Maintenance of this high speed is an advantage of the cascade arrangement over other schemes for matching and reading-out dc tunnel junction SQUID´s. True cascade operation was not obtained, due to coupling of Josephson oscillations from the first Stage of the cascade to the second.
