Sharper Detail, Shorter Cycles: High Performance Emitters
How do Tubes with HPE Emitters Work?
Compared to traditional filaments, HPE emitters generate electrons in a concentrated, regular shape.

Varex electron optics squeeze the beam into a tubular shape, as electrons accelerate from the emitter towards the target.

Focal spots result with shapes optimal for digital x-ray imaging. This spot is from an HPE-450-54 tube.
Advantages for Varex Imaging Customers


Maximum image performance per Watt is attained. This means less time required to achieve the desired image quality. Left Image: HPE Emitter
HPE Emitters generate less waste heat vs traditional emitters, meaning less strain on the high voltage connection.
Technology at The Heart of HPE Tubes

HPE Emitters are high performance components. Their ability to emit electrons in highly controlled fashion comes from careful development of the emitter material itself, as well as the supporting technology infrastructure.

Material science is at the heart of HPE emitters. Years of testing and making minute adjustments, let Varex engineer a product that delivers performance – reliably.

Exceptional performance needs exceptional control. Varex works tightly with HV Generator manufacturers to deliver highly stablekV and mA regulation.
