NanoTube N3 110 kV

Join the nanoscale resolution revolution

The highest imaging resolution across the full voltage range

The Excillum NanoTube N3 enables industry-leading resolution and stability in geometric-magnification X-ray imaging systems with no need for manual tuning.

The Excillum NanoTube N3 is based on advanced electron optics and the latest tungsten-diamond transmission target technology. Automatic e-beam focusing and astigmatism correction ensures that the smallest possible, truly round spot is achieved every time, every day.

The NanoTube N3 also has the unique feature of internally measuring and reporting the current spot size. In addition, advanced cooling and thermal design results in extreme stability over long exposures. This enables an unprecedented true resolution of 150 nm lines and spaces.

Features and benefits

The NanoTube N3 X-ray source consists of the head with dimensions 689 x 210 x 400 mm (L x W x H) including cables etc. The head has several mounting holes consistent with metric optic table mounting and is designed for upright or flat fastening, in any orientation including vertical or horizontal.

In addition, the NanoTube N3 consists of a power module and a chiller, both 4U (176 mm height, 19” rack), as well as a 1U (44 mm, 19” rack) control computer and a floor standing high-voltage generator, that all can be mounted up to 5m from the head.

The NanoTube N3 can be remotely operated through TCP/IP or directly through the GUI. The GUI can be operated on the source itself if it is equipped with monitor, keyboard and mouse, or on most computer platforms 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, 120-240 V, 16 A, 50/60 Hz.
Ambient: 20-30°C (stable within ± 0.2°C for optimal source stability), max 85% relative humidity.

True round spot

The true round spot of the NanoTube N3 is demonstrated by the highly symmetric images of a Siemens star resolution target. The innermost features are 150 nm.

The image on the left shows a SEM micrograph of a Siemens star and an X-ray projection radiograph is shown on the right.

Long term positional stability

Thanks to the advanced e-beam system of the NanoTube N3 and the integrated thermal control, excellent long-term stability is achieved. This graph illustrates the motion of the spot relative to a fix point on the anode over 8 hours as measured internally by the source when at thermal equilibrium. Naturally, great care must be taken regarding the stability of the imaging system to maintain the same stability throughout the imaging chain.

Excellent geometrical access

The end of the transmission target is the most protruding surface to allow for a sample to get as close as possible to the X-ray focal spot.

The front is furthermore cone-shaped to allow for a sturdy cone-shaped sample holder.
