The filament operates at 1800 °C, 3.5 V, 66 A, and 231 W, requiring careful matching to the power supply and source holder. It must be stored in a dry, inert atmosphere to prevent oxidation and maintained in a vacuum during operation.
- Electrical Matching: Confirm the voltage, current, and power ratings match the evaporation power supply configuration to avoid overload or short circuit.
- Thermal Management: Allow the filament to cool to room temperature before handling after use to prevent thermal injury.
- Mechanical Handling: Hold the filament by the base and avoid touching the wire elements to prevent distortion or breakage.
- Storage Conditions: Store the filament in a dry, inert atmosphere to minimize oxidation of the tungsten surface.
- Vacuum Operation: Use the filament only inside a vacuum deposition system to prevent oxidation and ensure proper evaporation.
Follow these steps to safely install and operate the filament in a vacuum deposition system. Ensure all electrical and mechanical matches are confirmed before use.
Required Equipment: Vacuum deposition system, Power supply, Source holder, Personal protective equipment (gloves, safety glasses)
- Inspect Filament
Inspect the filament for any signs of damage, bending, or contamination before installation. - Confirm Fit
Confirm the filament geometry reference P5 and dimensions match the source holder and required package quantity. - Mount Filament
Mount the filament securely into the source holder, ensuring the wire elements are not deformed. - Connect Power Supply
Match the voltage, current, and power requirements to the evaporation power supply configuration. - Evacuate Chamber
Evacuate the deposition chamber to the required vacuum level before applying power. - Apply Power
Apply power gradually to reach the operating temperature of 1800 °C while monitoring current and voltage. - Cool Down
Allow the filament to cool completely before venting the chamber and handling the assembly.
What power supply specifications are required to drive this P5 tungsten point source filament?
The filament requires a power supply capable of delivering 3.5 V, 66 A, and 231 W continuously, as specified in the technical data. The supply must also support the 1800 °C operating temperature, which may require closed-loop current or voltage control to maintain stable evaporation conditions. Confirm that the source holder and feedthroughs can accommodate the 4 in L × 1/2 in × 1/2 in H geometry and handle the 66 A current without overheating.
How does the 3-wire 0.030 in diameter construction affect the electrical loading and thermal performance?
The 3-wire × 0.030 in diameter construction determines the filament's resistance, resulting in a specified drive requirement of 3.5 V, 66 A, and 231 W to reach 1800 °C. This wire count and diameter provide a specific thermal mass and heating profile suitable for thermal evaporation; alternative wire counts or diameters would alter the voltage-current relationship and operating temperature.
What are the critical fit and compatibility factors for installing this filament in a vacuum deposition system?
The filament has a physical footprint of 4 in L × 1/2 in × 1/2 in H with a P5 geometry. Before installation, confirm that the source holder can accommodate these dimensions and that the electrical feedthroughs can deliver 66 A. Additionally, the 1800 °C operating temperature requires that all adjacent components (e.g., shields, shutters) are rated for high-temperature exposure.
Tungsten point source filament with P5 geometry and 3-wire × 0.030 in diameter construction, rated for 1800 °C operation at 3.5 V, 66 A, and 231 W, requiring precise matching to evaporation source holder and power supply before procurement.
Positive
- Defined high-temperature tungsten construction: Tungsten filament with 3 wires × 0.030 in diameter supports thermal evaporation at a rated operating temperature of 1800 °C, providing a stable point source for vacuum deposition workflows.
- Explicit electrical specification for source matching: Voltage (3.5 V), current (66 A), and power (231 W) are stated, enabling direct compatibility verification with the evaporation power supply and source assembly before installation.
Trade-offs
- Geometry-dependent holder fit required: The P5 geometry and physical dimensions (4 in L × 1/2 in × 1/2 in H) must be confirmed against the evaporation source holder; incorrect fit will prevent proper installation.
- Electrical loading must be pre-matched: The specified voltage, current, and power values require the user's power supply to deliver exactly these parameters; deviation may cause underperformance or damage to the filament or deposition system.
