HEATER MATERIALS
| Graphite | flexible (stable in form), minimal outgassing at the high temperatures, oxidation resistant below 500°C |
| Graphite + PBN coating | flexible (stable in form), minimal outgassing at the high temperatures, oxidation resistant below 800°C (depends on partial pressure of oxygen) |
| Graphite + SiC coating | hard, light and stable in form, oxidation resistant below 1400°C |
| SiC solid (β) | extremely hard, light and stable in form, low thermal expansion, durable to mechanical and electrical shocking, excellent resistance to reactive gases/oxidation |
The 1-2 axes motorised MBE manipulator is a high rigidity UHV specimen manipulator of modular construction, suitable for a range of R1 motorised continuous substrate rotation and Z translation.
It is prepared to heat the substrate up to 1400°C (EB heating, UHV conditions) with accuracy +/- 1°C. The station includes the substrate (standard up to 6 inch sample holder) positioner and allows precise angular position of substrate in relation to linear shutter.
Applications
The 1-2 axes motorised MBE manipulator is designed for MBE applications under ultra-high vacuum conditions. Heating is performed by resistive or EB methods. The manipulator can work in the vertical orientation.
Manipulator for MBE applications:
▪ sample holders: generally plate style
▪ prepared for reaching high temperature
▪ base pressure: 10-11 mbar
Option
▪ H2O shroud
▪ LN2 or H2O cooling
▪ side or integrated wedge shutter (possible with H2O cooling option)
▪ XY movement stage
▪ shutter on/off
