Dear Colleague:
Welcome to Quantum, a periodic e-newsletter for
professionals working with magnetic technologies. Quantum
is designed to keep you up to speed on applications, case
histories, and evolutions of quantum magnetometers in a variety
of disciplines.
In this issue:
Airborne
Developments
(Top)
Complete Airborne Systems.
This is our new family of Birds
for airborne exploration with the latest in technology based on
a unique optically pumped Potassium vapour that increases
magnetic measuring sensitivity over conventional technologies.
Increased sensitivity (0.0007 nT),
combined with high sampling rates (20 readings per second),
enables more detailed mapping of geologic structure, lithology
and geophysical anomalies related to the occurrence of gold,
base metal, platinum group metals (PGMs) and diamonds.
With the following advantages:
-
High definition range of multi
sensors configurations (Magnetometer, Vertical Gradient or
Tri-Axial Magnetic Gradiometer).
-
TRA series Radar Altimeter.
-
20 Hz DGPS with SBAS (WAAS /
EGNOS / MSAS) and OmniStar (Subscription not included.
-
GEM Data Acquisition Software
with real time Data and altitude display.
-
All Weather Highest sub-pico
Tesla Sensitivity.

Airborne
- NEW
GSMP-35A Sensor
(Top)
GEM Systems adopted potassium
magnetometer Model GSMP-35A to work in strong EM pulsed field in
the vicinity of the EM loops. SkyTEM of Denmark and Novatem
acquired potassium magnetometers with this feature for their
helicopter borne EM surveys and are now successfully surveying
in Canada and Europe.

Ground
Developments (Top)
As ground magnetics is one of the
most-frequently employed and effective geophysical methods
applied to mineral exploration, GEM continues to implement new
strategies for enhancing measuring techniques and results.
Basic R&D has led to the
development of a new generation of GPS functionality, designed
to assist exploration groups and contractors acquire,
high-quality magnetic results through better positioning
control, reduction of surveying (i.e. picketing) costs and
enhanced survey efficiencies.
Ground Developments
- NEW OmniStar / CDGPS
(Top)
GEM Systems offers newly created
built-in option OmniStar with CDGPS for their portable and
airborne magnetometers, called
GPS Option D.
With the new functionality all
GEM’s ground systems, such as the industry standard Overhauser
magnetometer / gradiometer, proton precession and optically
pumped Potassium ground systems, are beneficiated because CDGPS
has many advantages over other existing wide area correction
systems. Most importantly, it delivers superior correction
signal penetration, high accuracy and high resolution
differential GPS corrections that are critical to many dynamic
positioning applications. In addition, there is no subscription
cost for users of this service. These features make CDGPS an
ideal sub-meter positioning system for a wide range of
applications. On top of that it delivers a true position 20
times per second so at any speed the magnetometer is sampling it
will always have the real position.

Note:
CDGPS (Canadian Differential
Global positioning System) only works in Canada, with a
resolution of .7 meters.
OmniStar (Subscription or License
NOT included) with a resolution up to 20cm.
Ground Developments
- Backpack Mounted Potassium
Magnetometer / Gradiometer (Top)
GEM is releasing a new version of
its GSMP-35 optically pumped Potassium magnetometer (K-Mag)
designed to provide backpack-based, hands-free operation while
acquiring high sensitivity ground-based magnetics data. The
system eliminates the use of supporting sensor poles (with the
backpack), thereby providing convenience and greater efficiency
during survey operations.
The new K-Mag technology also
delivers sensitivity and high sampling (20 times / second) for
mapping of subtle geologic signals. The system’s high gradient
tolerance and higher range of measurement (up to 3 Gauss,
optional) is especially useful for exploring in areas with iron
formations, magnetite outcrops, and other similar targets.

Archaeology
-
Updated
with new discoveries
(Top)
Enclosed please find the link for
a book Named “Magnetic Survey for Archeology 10 years of Using
The Overhauser GSM-19 Gradiometer” where Tatyana N. Smekolava
take you in a journey of the practical aspects of the magnetic
surveys for the investigation of various archeological sites.
Archaeologists will definitely
have an interest in this new work produced by researchers in
Russia and Denmark over the last 10 years.
The book begins with an overview
of methods of magnetic surveying followed by a description of
magnetometers. The remainder of the book provides case histories
from many sites across Africa, the Middle East and Europe but
general lessons may also be applicable to other investigations
in other parts of the world
