# Industrial Specification: Gas Chamber

## 1. Technical Definition
The sealed enclosure within a Gas Discharge Tube (GDT) that contains the ionizable gas mixture.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-10 bar absolute pressure**. Failure boundary: **15 bar internal pressure causing permanent plastic deformation of chamber walls**, Mechanism: **Exceeding yield strength of 316L stainless steel (205 MPa) due to Paschen's law breakdown at reduced pressure-distance product**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in gas chambers for Gas Discharge Tubes?
**A**: Gas chambers are typically constructed from alumina ceramic, glass, or metal-ceramic composites to provide hermetic sealing and withstand high temperatures during gas discharge events.

### Q: What components make up a gas chamber assembly?
**A**: The main components include the chamber enclosure, electrodes, seals, and a gas fill port for introducing the ionizable gas mixture into the sealed environment.

### Q: How does the gas chamber function in surge protection devices?
**A**: When voltage exceeds a threshold, the ionizable gas inside the chamber ionizes, creating a low-resistance path that diverts surge currents away from sensitive electronic components.
