3 System Components
This section describes the types and functions of the various sub-systems that are delivered
as part of our AVANCE NEO NMR systems. These include the following:
• Superconducting Magnet Components [}21].
• Console and Other System Components [}22].
• CryoProbe System (Optional) [}23].
• Other Optional Components [}25].
3.1 Superconducting Magnet Components
The superconducting magnet is a complex system producing a very strong, homogeneous,
and stable magnetic field as required for NMR. This section describes the various sub-sys-
tems of the magnet system.
Magnet: The magnet system’s main component is a superconducting coil
housed in a cryostat. The cryostat consists of an outer vacuum enclo-
sure, a liquid nitrogen vessel, some radiation shields and a liquid he-
lium vessel.
The magnet uses both liquid nitrogen and liquid helium. The magnet
coil is immersed in liquid helium inside a dedicated helium vessel. Liq-
uid nitrogen fills a different vessel and reduces the helium evaporation
rate.
After the initial charging with electrical current, the magnet runs in per-
sistent mode. The current runs in a closed loop inside the system and
the magnet itself is no longer connected to a continuous power supply.
Maintenance: Magnet maintenance consists of refilling the system with cryogenic flu-
ids at defined time intervals.
