GEO/ CRYOGENIC/ NDE INSTRUMENTATION
Tristan designs and fabricates custom magnetometer systems to study the magnetic properties of samples. SQUID systems are extremely sensitive instruments designed to detect small electromagnetic signals. By combining SQUID electronics with various special purpose probes and auxiliary electronics, laboratory systems having a variety of capabilities are made available.
magnetic imaging systems
Superconducting amplifiers (SQUIDs) are used to amplify magnetic signals detected by a large array of small detection coils. The detection apparatus is kept at cryogenic temperatures by a vacuum insulated vessel (dewar). Tristan developed fabrication methods allow the detection coils to be placed extremely close to the patient without loss of sensitivity or risk to the patient. Tristan develops custom magnetic imaging systems.
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 could be detected with Tristan SQUID magnetometers.
