Yelo Travelling Wave Tube (TWT) Test Systems

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 & 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)
