MetalJet C2
Attractive and cost effective brightness

The MetalJet C2 offers an attractive, cost effective version of the MetalJet X-ray source technology with simplified electron optics producing a round electron beam focus.

The MetalJet C2 features Excillum’s unique liquid-metal jet anode technology and advanced electron optics. It delivers significantly higher brightness than a solid-target microfocus X-ray source, with an excellent spot quality. With the MetalJet C2 you will get a high-performance microfocus X-ray source, at a competitive price. If you in the future need even higher brightness than what is achievable with the round electron-beam focus, you have the possibility to upgrade to the MetalJet D2+, to get the world’s brightest microfocus X-ray tube.

With the introduction of Dynamic Adaptation technology the practical cathode lifetime has been further extended 2-4x, up to a full year of 24/7 operation depending on application.

Characteristics

Installation and operation

The source consists of the head and the pump system with dimensi- ons shown in the drawing. The head has to be mounted essentiallystraight above the pump system. The coupling is semi-rigid, allowingsome movement of the source head.

In addition, the MetalJet C2 consists of two 4U (176 mm height) 19” rack electronics boxes and a floor standing air/water chiller (69×36×62 cm), that can be mounted up to 4m from the head and pump system.

Sources operating with ExAlloy I2 furthermore have heater jackets around parts in the alloy recirculation loop as well as an additional 3U (133 mm height), 19″ rack mounted controller.

The source can be remotely operated through TCP/IP or directly through the GUI. The GUI can be operated on the source itself if it isequipped with monitor, keyboard and mouse, or on most computerplatforms with a TCP/ IP connection to the source.

The source cannot be operated as a standalone unit and must be integrated into a system providing the proper interlock connections.

Mains: AC, single phase, 200-240 V, 16 A, 50/60 Hz.

Ambient: 20-25°C (stable within ± 0.2°C for optimal source stability), max 85% relative humidity.

Safety and compliance

Excillum’s X-ray sources are compliant with the Machinery Directive 2006/42/EC, RoHS Directive 2011/65/EU and Low Voltage Directive 2014/35/EU. Excillum’s X-ray sources are a sub-assembly and therefore excluded from the EMC Directive 2014/30/EU, hence also conform to the definition of partly completed machinery and so should not be CE marked. Our X-ray sources are intended for system integration into customer equipment. The system integrator is solely responsible for final certification and safety compliance. X-rays emitted from the source are harmful for the human body and it is the sole responsibility of the system integrator to comply with all regulations and to protect all personnel during operation. The X-ray source may be subject to local government radiation hazard regulations.
