Equipment
|
* Permalloy shielded
room was built to make sensitive to geomagnetic noise experiments. Size:
2.5m x 2.5m x 2.5m |
* 2-G cryogenic magnetometer (horizontal
option with demagnetization, ARM and IRM coils). Funded by the Canadian Foundation for Innovation
(CFI) and the
|
Geophysics
technicians Dave Schuler and Len Tober during the final
stage of the 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.
* In
collaboration with Dr. D. Potter we installed and now testing the Magnetic Measurements Variable Field
Translation Balance (MMVFTB). MMVFTB 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. |
