Choice of 4 or 5 axis configurations
Both the XL-T and XL-R range of multicentres are available in 4 or 5 axis configurations to suit the application requirements.
|4 axis (X,Y,Z,R1)
||5 axis (X,Y,Z,R1,R2)
|The 4 axis option provides a range of X, Y and Z movements with magnetically coupled rotary drive providing the polar (primary) rotation.
||The 5 axis option provides a range of X, Y and Z movements with magnetically coupled rotary drives providing both the polar (primary) rotation and azimuthal (secondary) rotation.
Choice of resistive and e-beam heating options
Both the XL-T and XL-R range of multicentres can provide resistive sample heating to 900oC or e-beam sample heating to 1,200oC (typical values).
|Resistive heating to 900oC
||E-beam heating to 1,200oC
|Robust self-supporting Ta foil heater, for minimum outgassing and large ratio of heated to open surface area ensuring heater longevity. The filament is also Yttria coated to provide additional robustness in oxidising atmospheres and for protection in the event of an accidental vent. Note: heating limited to 600°C with LHe option.
||For higher temperature requirements the e-beam heating option achieves sample temperatures up to 1200°C. To upgrade to e-beam heating simply requires a change of power supply unit.

Choice of LN2 and LHe cooling options
Both the XL-T and XL-R range of multicentres can provide LN2 sample cooling to -170oC and the XL-R can offer LHe sample cooling to 15K (-258oC) (typical values).
|LN2 cooling to -150oC
||LHe cooling to 15K (-258oC)
|Innovative LN2 cooling module provides sample cooling down to <-150°C with continuous azimuthal rotation and temperature measurement. Typically the LN2 cooling can achieve sample temperatures to <-170°C. The LN2 circuit is routed through the hollow shaft with the coils inside the service collar to minimise the swept volume of the stage head.
|Based on UHV Design’s own continuous flow cryostat, cryogenic temperatures below 15K can be achieved in less than one hour.
