Cargo Inspection X-Band
Cargo Inspection X-Band

Comeb specializes on the manufacture of compact linear accelerators for medical, industrial and research applications. In order to achieve such compactness, X-Band technology is used.

Recently, the company has delivered a  1 MeV linac to be used for aviation cargo inspection.

The cavity consists in 8 brazed copper cells and an input waveguide in the central position. Total length is only 15 cm. The cavity was designed as an X-band pi/2 bi-periodic structure and operates with a 30 MV/m accelerating gradient.

The linac was tested at STFC (Science and Technology Facilities Council). Measurements of the radiation dose and electron beam energy spectrum are attached below.


RF parameters are:


-Frequency                              9298 MHz

-Nominal Bandwidth                 1 MHz

-Total peak output power          1,5 MW

-Pulse Repetition Rate Range      100 Hz


-RF Pulse Width                        5 µs
