Measurement probes are available as fixed sample.
The PCB and LCC holders are ceramic Aluminium-Nitride (AlN) to optimise thermal conductivity.
Electrical contact plating is Ni free to minimise the remnant field effects in the sample domain.
The following sample holders are available with our range of measurement probes:
During the process of mounting the sample into the sample holder, an ESD plug will be inserted. This plug links all the electrical connections to the sample together ensuring that no damaging voltages can be generated across the sample due to ESD.
The measurement cable is a carefully specified cable constructed of 13 twisted pairs, 10 pairs of 26 AWG tinned Cu and 3 pairs of 22 AWG tinned Cu. Each pair is individually screened with a foil screen. Each screen has external insulation to isolate it from all the other screens. Each screen also has a drain wire.
Measurement probes are available as fixed sample. These probes are ideal for electrical transport and Hall effect measurements from DC to GHz RF. Featuring de-mountable sample holders for in-plane and out-of plane measurements, ESD protection and measurement isolation.
Each probe is available as Sample-in-Gas (SIG) with a Sample-in-Vacuum (SIV) variant. The probe chassis consists of three thin-wall stainless-steel tubes to provide a rigid, straight, low-thermal conductivity structure and create separate electrically isolated spaces to keep measurement looms shielded from diagnostic and drive wiring.
This sample-in-vacuum ³He refrigerator achieves less than 300 mK for more than 40 hrs and achieves 50 µW of cooling power at 350 mK for over 6 hrs. The HelioxVT uses a cold gas environment with a 50 mm access, therefore no need for a 1 K pot on the insert.
The Kelvinox®JT is a small, dipstick-style, dilution refrigerator, which features a Joule-Thomson condensation stage. It means the KelvinoxJT can operate in any 4 K environment – wet or dry – as it does not rely on a 1 K pot.
Wide temperature range: when operated in a VTI, the temperature can be controlled between 25 mK and 300 K. Quick cooldown time from room temperature to base in less than 6 hours.
Our Sample Protect solution is a break out box which provides experimenters with an end-to-end method of protecting sensitive samples from accidental electrostatic discharge (ESD). The system comprises of a rack mount SampleProtect Switching Unit (SPSU) linked, via measurement grade cables and sample probes, with sample holders which include an additional socket for an equi-potential plug.
