First group dinner at the 2025 APS March Meeting!
Quartz rod with a special design intended for ultra-high resolution thermometry using a single Josephson junction.
Chip carrier on an Attocube nanopositioners stack.
Attocube nanopositioner.
Optical microscope image of a quartz pipette before pulling it into a SQUID-on-tip, or multi-SQUID-on-tip. The latter allows in-situ control over the SQUID's response to magnetic field.
Optical microscope image of an asymmetric quartz pipette before pulling it into a SQUID-on-tip with asymmetric junctions.
SQUID-on-tip holders. Right: the usual two-terminal SQUID. Left: an advanced four-terminal SQUID with increased tunability.
SQUID-on-tip mechanical and electrical holders.
A sketch of a SQUID-on-tip holder.
SQUID-on-tip and holder.
Circuit schematics for SQUID noise measurement electronics.
Aligning a SQUID-on-tip against a sample prior to cooldown.
Tuning fork transimpedance room-temperature amplifier using OPA657 op-amp. The design is based on https://doi.org/10.1063/1.4769271
