PLD Components
Thermionics offers an extensive line of substrate and target manipulators as well as load lock and sample transfer systems for PLD systems. Our standard modular components can be configured in a variety of ways to meet your specific PLD system design. We can also design, integrate and certify complete PLD systems.

| Sample orientation | any |
| Sample heating | SHQ to 700°C (water-cooled heater) |
| Vacuum environment | UHV, O2 |
| In-vacuum sample transfer | optional |
| Base flange | 8″ |
Typical PLD Configuration and Variations
Example 1. Typical PLD Configuration
The substrate and target are introduced through a load lock chamber opposite the target gearbox. The substrate is then rotated on its polar axis to face the target gearbox. The substrate can be moved out of the way for transfer of the targets. This is one of the most common and economical configurations.
Example 2. Vertical PLD Configuration
This design features up-facing, gravity-held target holders to accommodate liquid, powder, or conventional targets. A custom transfer fork moves substrates and targets into place via standard load lock chamber.
Example 3. Simple PLD Configuration
This design offers basic substrate and target devices with no XY or Z adjustment. Substrate and target changes are done at atmosphere.
Example 4. Multi-Purpose PLD Configuration
This design permits MBE growth, via bottom-flange-mounted evaporation sources, as well as PLD growth. Substrate assembly faces the side of the chamber for PLD, the bottom for MBE, and the other side for in-vacuum transfer of substrates.

TGB-4-1 Target Gearbox for Laser Deposition
Azimuthal Target Rotation:
The TGB is a target gearbox only. To be a complete target drive system it must be connected to two rotary feedthroughs, one for the target rotation and the second used for clocking the targets into position to face the laser from behind the protective shroud.
- Provides continuous target rotation during ablation
- Holds 4 one-inch O.D. targets
- Includes shroud/probe tube exposing one target at a time (shroud actuation requires RNN or WOA)
- All stainless steel construction
