utilizing a coil wound from High Temperature Superconductor
(HTS) wire the Model 5751 Short Solenoid
is a compact assembly for the generation of an axial magnetic
field that may be continuously varied between ±1T.
The field uniformity is better than 1% over a central
cylinder of 10mm diameter by 8mm length in a room-temperature
bore of 35mm inside diameter, 190mm outside diameter and
72mm axial length.
A compact, integral Cryocooler cools the HTS Coil by conduction.
The overall radial length of the Solenoid and Cryocooler
is 595mm with a weight of 10kg. Flexible leads to the
Cryocooler Compressor enable the Solenoid to be mechanically
mounted in any direction.
The basic 5751 System includes the Solenoid, Cryocooler
and Compressor, Bipolar Power Supply, Interlocks and all
half length approximately equal to the bore diameter provides
an open geometry for development and production measurements
of magnetic properties using radiation beams including
MOKE (Magneto-Optic Kerr Effect) and SMOKE (Surface MOKE).
scanning techniques like SEMPA (Scanning Electron Microscopy
with Polarization Analysis), STM (Scanning Tunneling Microscopy)
or AFM (Atomic Force Microscopy) may also be made easier
with the open geometry.
and biological separations requiring controllable, axial
fields with access for optical and electrical probes.
and ion beam focusing using controlled solenoidal fields
with short axial length.
