Abstract: A cryogenic coil assembly including a coil substrate with a flat surface, and a number of radial channels cut into a region of the flat surface. The cryogenic coil assembly also includes a spiral coil covering the radial channels, and a chemical bonding agent for bonding the spiral coil to the coil substrate. The chemical bonding agent is present within the radial channels.

Abstract: An electronic measuring device is described that can include first and second input inductors connected in series. A shunt inductor is connected in parallel with the second input inductor. Optionally, an additional shunt inductor may also be used in parallel with the first input inductor. The first and second input inductors are inductively coupled to first and second SQUIDs which are in turn inductively coupled to first and second feedback inductors. First and second SQUID controllers are connected, respectively, to the first and second SQUIDs as well as the first and second feedback inductors. The first and second SQUID controllers are also connected to a processor. The processor is operable to process the output of the first and second SQUID controllers to detect unlocking events in the output of the first SQUID controller.

Abstract: A method of attaching a first member of one of quartz and a ceramic to a metal member. The method includes creating a hole in the metal member, the hole being smaller in size than the size of the first member over a temperature range, heating the metal member to a temperature sufficient to expand the hole to allow insertion of the first member in the hole, inserting a portion of the first member into the hole, and cooling the metal member to form a joined structure of the first member and the metal member.
