advantages of even-N for stray field
suppression, N = 2 is almost
the magnetic field was generated by a stray field
of a solenoid equipped with a ferromagnetic core with clearance.
The design of the DXM Series reduces failure modes often found with plating and solder terminated wires and leads, and the multi-gap technology used to manufacture the device also reduces fringing flux and stray field
The recording head for perpendicular recording consists of a single pole inductive write head with a suitable flux return path designed for high efficiency, low stray field
sensitivity and sharp field gradient capable of writing on perpendicular media with coercivities in excess of 5000 Oe.
With already six installations at customer sites worldwide, this unique 950 MHz magnet, which has only been delivered by Bruker, provides ideal capabilities for demanding multidimensional biological NMR applications, while at the same time requiring a relatively small footprint due to its small stray field
Our unique and patented cryogen-free superconducting magnet technology allows us to build portable magnets with a small footprint, low weight, and very low magnetic stray field
, eliminating the need for liquid helium," says Shahin Pourrahimi , founder and president of SSI.
There are inevitably stray fields
within the "zero-field" gaps that give rise to unwanted Larmor precession around the local stray field
Ascend magnets feature advanced superconductors and proprietary magnet technology which together enable the design of smaller, lighter magnet coils, resulting in a further significant reduction in physical size, weight, magnetic stray field
, drift and cryogen consumption.
The result is the most reliable 900 MHz magnet for NMR applications with a relatively small stray field
and footprint for straight-forward installations.
Remarkably, the 950 US2 magnet features a 5 Gauss radial stray field
of only 3.
Easy, cost efficient siting is supported by the minimized stray field
and compact design of the horizontal magnet.
Ascend magnets, available as standard bore (54mm) magnets for 700, 800 and 850 MHz , are extremely convenient and easy to site, even in single story labs, due to their compact size and minimal stray field
