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. |
