Twisted Pair Wiring
Measurement Infrastructure
Bluefors offers high-quality Twisted Pair Wiring for direct current (DC) measurements integrated into the cryostat.
Twisted Pair Wiring is available in sets of 12 pairs (24 wires). All wires are factory-twisted and then bundled in fiberglass sleeving for protection.
To guarantee cryogenic performance, all DC wiring is tested at room temperature (RT) and at nitrogen temperature before integration.
Finally, the integrated DC wiring is tested while the system is at base temperature. At every temperature stage, the bundle is thermally anchored on gold-plated copper bobbins.
One KF40 LOS-port can fit up to 4x sets of 12 twisted pairs.

The TWP cable can have additional 25-pin micro-D connector breakouts at any flange to make the installation of customer devices easy. In the standard installation, the micro-D connector termination from the higher temperature serves as a breakout post and it mates with the micro-D connector termination of the continuing TWP wiring cable.
Our TWP cables can be equipped with the electromagnetic (EM) shielding. We have a solution where we use a stainless-steel sleeve around the wires together with a shielded housing for the micro-D connectors.
Note: The shielding is not available for Attocube wiring.
The QDevil‘s QFilter is a compact multi-stage low-pass filter with 24 lines. It rejects noise and ensures lowest possible electron temperatures in the lines going to your quantum electronics devices. This filter concept originates from Harvard University and the University of Copenhagen.
A QFilter contains two filter banks, one with RC circuits and one with LC circuits. For filtering 24 lines these two banks are connected in series using a short jumper cable. For filtering 48 lines, the QFilter can be pigtailed without the use of the jumper cable.
Note: The QFilter is not available for Attocube wiring.
