can switch between superconducting and normal state using the integrated heater. It can be used in low current superconducting circuits such as pickup loops in SQUID-based magnetometers or SQUID input circuits for various detectors. It is successfully being applied in low field MRI (magneto resonance imaging) applications all over the world.
The model SW1
has an Nb-based thin film bifilar switching element with low inductance and an integrated heater. The switching time is as low as few microseconds. The customer can select from two switch versions on every chip.
is hermetically sealed inside a glass fiber package. It has solder terminals with normal metal wire bond connections to the heaters and Nb terminals with screws for true superconducting connection to the switching element.
SQUID sensor models CE1blue
are available in a compact package combining SQUID sensor and superconducting switch model SW1.
