(7) Cold Stage |
| Features | Benefits |
|---|---|
| Active LN2-cooled sample block | Permits analysis of otherwise volatile materials in a vacuum |
| 2 separate cooling circuits | Permits a cold plate near the sample to be held at lower temperature than sample |
| On-stub heater cartridge option | Additional fine control of sample temperature and also above ambient heating to ~100°C |
| On-stub thermometry | Precise temperature measurement |
| Very stiff mechanical design | Permits high resolution imaging (minimise drift during data acquisition) |
| X, Y, Z motion stage: ±12mm on all axes | Full analytical coverage of the 22mm x 22mm sample stub |
| Pneumatic sample clamp | Ensures good thermal contact (<80 K on stub). Released for easy sample exchange |
| Option for digital micrometer readouts | Precision positioning |

Kore has designed a number of high-precision sample stages for operation in UHV environments. For matching the cryo preparation system, we have designed an X, Y, Z stage with ±12 mm of motion in all directions. The stage fits on to a 6" flange and is designed to maintain samples cold for surface analysis of otherwise volatile materials. Using on-stub thermometry and control of the LN2 flow, the sample can be held at any temperature from −180°C to room temperature to within ±1°C. The X, Y and Z motions are achieved through manual, rotary motion, and an option exists to equip the drives with digital micrometer readouts for greater positioning precision. |
