Yelo Travelling Wave Tube (TWT) Test Systems

Yelo has a wealth of experience in developing and customizing test systems for the Travelling Wave Tube (TWT)market. Yelo’s TWT testers feature specialized power supplies, measurement equipment, and comprehensive control and safety systems.

A rugged PLC is used to control all voltages and perform all monitoring functions. User interface and datalogging functions are provided by a supervisory PC that is electrically isolated from the PLC. Power supplies are solid state with optical fiber barriers to ensure that all control/monitoring is carried out at safe voltages, and with maximum noise immunity. All safety interlocks are hardwired, and the testers are equipped with emergency shutdown features for added security.

Features:

• Testing, focusing, and ageing, continuous or pulsed operation
• Solid state switching for smaller footprint and enhanced control
• PLC/PC control for optimum flexibility
• Cathode supplies to 40 kV at 0.5A mean and beyond
• PRF up to 1 MHz
• Tube rise/fall times of typically 0.05-20uS
• Cathode energy, current limiting, and crowbar for TWT protection
• Hot/cold plates, jigs and fixtures, thermal management
• All supplies are modular and easily replaced or repaired

Benefits:

• Full automation allows for complex testing to be performed without supervision
• Huge reduction in operator skill level requirements
• Reuse existing fixturing and safety systems to reduce costs

Supported tube types:

• Modulated grid TWT
• Pulsed TWT
• Klystrons (linear-beam tubes)
