Compact stages (View Product)
High stability, precision stages (View Product)
Configurable analytical stages offering up to 5 axes of motion and options for sample biasing, heating to 1200°C and cooling to <30K. MultiCentres can be configured to accept most common surface analysis sample holders including pucks, flags and ESCA stubs.
The MultiCentre and associated accessories provide a complete solution for sample transfer and manipulation. Typical applications include analytical instrumentation for surface analysis equipment and synchrotron end stations.
The MultiCentre range includes the XL-T Series which provides compact single bellows stages and the XL-R series which utilises dual bellows with dual-point support to provide increased stability and precision.
Each series offers a full range of options including resistive or e-beam heating, temperature measurement, sample biasing/current measurement and LN2 and LHe cooling options. MultiCentres are unique in their ability to provide continuous azimuthal rotation and temperature measurement even when cooling with LN2 and heating to 1200°C.
Multicentre Key Advantages
- Compact and high stability, high precision stages
- Modular stage design allows functionality to be configured to suit application
- Innovative sample stage with ultra compact swept volume and unique range of additional stage options
- Heating to 1200°C & cooling to <30K (with LN2 precooling to reduce LHe consumption and costs)
- Unique ability to provide continuous azimuthal rotation and LN2 cooling
- Flag, puck and ESCA sample compatible stages
Future-Proofed Modular Design
The innovative MultiCentre range can be configured to match your application requirements. Should your requirements change in the future, the MultiCentre can be upgraded to include additional functionality.
For example, the unique uncluttered stage design provides space to include additional sample parking stages.
This ability to add additional functionality when required provides an economic route to future proofing your purchase, ensuring that the MultiCentre will remain at the forefront of surface science applications.
Configure To Suit Your Application
The modular XL-T and XL-R series of MultiCentres can be configured to meet your requirements.
Choose 4-axis for polar rotation only, and 5-axis if azimuthal rotation is also required. In addition, heating and cooling can also be specified. If sample heating is required, resistive heating to 900°C and e-beam heating to 1200°C options are available.
If sample cooling is required, LN2 cooling to <-150°C and LHe to <30K options can be included.
Compatible sample handling throughout all experimental modules is essential to maintain full system integration. UHV Design offers a range of Industry-standard Transfer Solutions which includes Flag-style, Puck-style and ESCA Stub options, all three of which can be fitted to either wobble sticks or PowerProbes.
In addition to the small swept volume and generally uncluttered design, the flat area of the platform adjacent to the sample plate itself can be utilised for additional modules if required. Some examples of our innovative parking stages are shown below.
Single flag-style parking position for 5-axis stage
5-axis flag-style heat / cool stage with the following additional features:
Single flag-style sample parking position which can loaded from either side by a wobble stick, is electrically floating for biasing and sample current measurement, and can be cooled.
Toggle mechanism which can be operated by a wobble stick to disengage the thermocouple from the back of the sample plate. Normally this functionality is accomplished by the forks on the magnetic transfer arm which engage in the end of the manipulator and disengage the thermocouple in the process.
Two level parking positions for 4-axis stage
4-axis flag-style heat / cool stage with a 2 level parking stage, both electrically floating and coolable into which can be loaded from either side:
- 2 standard flag samples, or
- two direct current heating flag samples, or
- a mixture thereof
- a special flag-style sample plate with a QMB (Quartz Microbalance) FTM (Film Thickness Monitor) mounted on it, or
- a special flag-style sample plate with an e-beam heater module which when loaded into the lower position can be used to heat a standard flag-style sample in the upper level to 1200°C
