8613/HY1A Hydrogen Thyratron

The 8613/HY1A  by EG&G is a hydrogen-filled, triode thyratron featuring a jumbo four-pin bayonet base and a hydrogen reservoir for extended lifespan. This rugged, compact tube is a plug-in replacement for the 5C22 glass hydrogen thyratron, making it ideal for use in high-performance systems with space constraints.

Key Features:

• Rugged ceramic construction: Ensures durability and reliability in demanding environments.
• Hydrogen reservoir: Promotes long-term stability and performance.
• Compact design: Facilitates integration into smaller systems.
• NAVSEA Specification compliance: Meets stringent quality and performance standards.
