Radial Distribution Systems
Designed to transfer samples between multiple analysis, deposition or preparation chambers that are connected to it.
Manufacturer
Prevac
Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.
Key Features
- Standard or telescopic transferring arm
- By rotating only one rotary feedthrough you can move the transfer arm in and out, rotate the sample holder around the arm axis, rotate the mechanism between transfer ports and lock/unlock the sample holder
- Chamber body diameters from 550 to 1200 mm (can be customised)
- Configured with TSP and transfer mechanism with rack-and-pinion rotary motion feedthrough
- Time to transfer between two chambers < 45 sec. (manual mode) – fast transfer time allows cold samples to stay cold (temperature rise also depends on initial temperature and heat capacity)
- Fast & reliable drop-proof transfer of hot & cold samples
- Up to 8 transfer positions to other UHV chambers with automatic sample positioning
- Guaranteed base pressure: 10-11 mbar range after 48h of bakeout. 10-10 mbar during transferring
- Numerous viewports
- Equipped with additional ports with UHV connecting flanges for future versatility
- Can be equipped with application matched vacuum pumps to achieve the best pressure range (e.g. turbo, ion, getter or titanium sublimation pumps)
Description
The chambers are normally mounted at the centre of a series of chambers, acting as a central distribution hub for cluster tools. The transportation and rotating mechanism of the RDC chamber provides repeatable and accurate sample transfer to other chambers. The radial distribution chamber mechanism is a development of the linear rack-and-pinion transporter, where a single-ended rack-and-pinion is precisely rotated by a precision rotary drive until it is aligned in a pre-set position at a radial port. Once locked into position, the same rotary drive transfers the rack out through the port.
