Tristan Technologies, Inc./Products

Biomagnetism Electrical measurements of physiological potentials are well established in clinical diagnostics. The flow of an electrical current creates a corresponding magnetic field. Thus bioelectric activity will generate biomagnetic fields. These fields can be detected with Tristan SQUID magnetometers. For many of the classical electrical techniques such as ECG and EEG, there are corresponding...

PVP and MFP Noise

Introduction to SQUIDs Laboratory PVP and MFP Noise Sources Refrigeration PVP and MFP Noise Sources This is a step by step tutorial on how to find noise sources. It is not intended to be the final answer, but hopefully most possible noise sources will be mentioned and will provide the clues to obtaining a sufficiently low noise system. This also assumes that you are having some type of difficulty ...

Refrigeration

Introduction to SQUIDs Laboratory PVP and MFP Noise Sources Refrigeration Refrigeration CRYOCOOLER APPLICATIONS The disadvantage of liquid cryogens is that they must be replenished, sometimes on a daily basis. Mechanical refrigerators eliminate that chore, but add cost, vibration and, in the case of SQUID-based instrumentation, magnetic noise. Cryocoolers can be used to reduce boiloff by cooling r...
