Equipment

*          Permalloy shielded room was built to make sensitive to geomagnetic noise experiments. Size: 2.5m x 2.5m x 2.5m

Description: Description: Description: Description: Description: Description: D:\Sites\MySite\Lab_files\Jason-2.jpg

Jason Han is using the Bartington thermo system inside of the shielded room

*          2-G cryogenic magnetometer (horizontal option with demagnetization, ARM and IRM coils). Funded by the Canadian Foundation for Innovation (CFI) and the University of Alberta.

Description: Description: Description: Description: Description: Description: Cryomag

Geophysics technicians Dave Schuler and Len Tober during final stage of cryogenic magnetometer installation in December 2006.

*          Spinner magnetometers. The laboratory maintains two spin magnetometers: Schonstedt SSM-1A Fluxgate Spinner Magnetometer measures remanence > 1 mA/m (acquired in 1971) and Molspin flux gate slow spin magnetometer (acquired in 1972).
The magnetometers are used for high-sensitivity work for both low and strongly magnetized materials. The flux-gate instruments, equipped with digital data logging and reduction, have a practical sensitivity of 5 x 10-7 emu. Typical measurement time per sample is 4 minutes.

*          Bartington susceptibility meter. The MS2 Magnetic Susceptibility System with sensors and software for field and laboratory use including anisotropy measurements.
Susceptibility/Temperature System. A system for the measurement of magnetic susceptibility over the temperature range -200°C to +900°C.
Sensors:
MS2B - Laboratory sensor for dual frequency measurements on 25.4mm cores or10ml samples.
MS2C - Range of core logging sensors with different diameters for measurements on sediment cores with no metal cladding.
MS2F - Probe with 15mm diameter for high resolution surface measurements.
The data are recorded and reduced automatically by an online computer. Anisotropy of susceptibility can be measured with extremely sensitive apparatus made at the U of Alberta.

*          The portable KT-5 Magnetic Susceptibility Meter for field measurements.
This portable, hand-held unit can be used in the field to analyze and classify rock types or core samples. It measures the volume magnetite content of rocks to extremely low levels and thus can identify very minute quantities of magnetite, titanomagnetite, ilmenite and pyrrhotite.

*          Demagnetization equipment: Alternating field and thermal methods. The AF unit operates at 400 Hz, producing a maximum magnetic field strength of 1500 Gauss (0.15 Tesla). The sample is held in a reciprocating tumbler to reduce spurious magnetization induced by AF treatment. Thermal demagnetization is carried out in a shielded permalloy room (internal magnetic field less than 5 x 10-5 Gauss) which holds up to 40 standard specimens per4-hour heating/cooling cycle. Heating is conducted in air atmosphere. We also have the Thermal Demagnetizer ASC Model TD48-SC (see details at http://www.ascscientific.com/td48.html ).

Shawn Walker (graduated in 2007) is using the AF Degausser.

*          Electromagnet Isothermal Remnant Magnetization is imparted to the specimen at room temperature with an electromagnet, capable of producing DC fields up to 10000 Gauss (1 Tesla). Magnetic remanence is then measured with one of the magnetometers. Saturation remnant magnetization and coercivity of remanence are measured with this system.

*          Rock drills and other field equipment. The laboratory maintains a full complement of portable rock drills, sample orienting equipment, and sediment sampling tools.

*          Rock drills and other field equipment. The laboratory maintains a full complement of portable rock drills, sample orienting equipment, and sediment sampling tools.

*          The Variable Field Translation Balance (VFTB) is an instrument for measuring isothermal magnetizations in variable fields (e.g., hysteresis loops) as well as the temperature dependence of the associated magnetic parameters. It is specifically designed to measure the weak magnetizations commonly encountered in rock magnetism. We can determine grain size and composition. Ferromagnetic, paramagnetic and diamagnetic components could be evaluated.
