Varex's high-energy linear accelerators, Linatron™, can be found in most cargo screening systems throughout the world. They reliably generate the necessary energy to fully penetrate completely loaded containers and carefully sense different materials.

As Varex continues to innovate and advance imaging technologies, our portfolio of linear accelerators includes interlaced dual-energy technology that offers even greater material discrimination than ever before. We also have an option to alternate X-ray energies on a pulse-to-pulse basis.


Linatron XP

The Linatron XP consists of an X-band, pulsed X-ray source, and modulator housed in separate transportable enclosures. Designed for mobility, the XP brings practical high-energy imaging capability to security and NDT field applications.
 It is available in either air-cooled or liquid-cooled configurations. For additional flexibility, the beam centerline can be configured in one of three positions to optimize the primary beam path for a given application. Several cone, fan, and slit beam collimation options are also available. For more information, download the Linatron XP Datasheet. Linatron XP - linear accelerator


Linatron M

The Linatron M product family represents the most popular X-ray accelerators available for the security and NDT markets. Linatron M - linear accelerator
These accelerators are available in several versions that vary by output energy and shielding, as well as other customer-specific features. 

  • Linatron M1

Typically used for both security and NDT applications, the Linatron M1 provides a nominal output of 1 MeV, but can be configured for outputs ranging from approximately 0.9 to 1.5 MeV. It has a relatively small size, light weight, and available shielding packages. For more information, download the Linatron M1 Datasheet.

  • Linatron M3

Typically used for both security and NDT applications, the Linatron M3 provides a nominal output of 3 MeV, but can be configured for outputs ranging from approximately 1 to 4.5 MeV. Its relatively small size, light weight, and available shielding packages make it ideal for truck-mounted applications. For more information, download the Linatron M3 Datasheet.

  • Linatron M6

The Linatron M6 offers a nominal 6 MeV output, allowing more penetration than the M3 and making it suitable for inspecting larger objects. It is used for both security and NDT applications. The output is nominally 6 MeV, but the dual energy versions (M6A) are available with a second, switchable lower energy output. For more information, download the Linatron M6 Datasheet.

  • Linatron M9

The Linatron M9 is primarily used for fixed site security and NDT applications where size, weight, and shielding are less restrictive than in vehicles. The output is nominally 9 MeV, but the dual energy versions (M9A) are available with a second, switchable lower energy output. For more information, download the Linatron M9 Datasheet.


Linatron Mi

The Linatron Mi is a dual energy Linatron system that is specially designed to switch energy pulse by pulse. This feature is primarily intended for X-ray container screening applications in the security market, where alternating energies allow enhanced material discrimination and the potential for automatic identification of contraband materials. Linatron Mi - linear accelerator
The Linatron Mi is currently available in two versions:

  • Linatron Mi6

The Linatron Mi6 has nominal energy outputs of 6 MeV and 4 MeV.

  • Linatron Mi9

The Linatron Mi9 has nominal energy outputs of 9 MeV and 6 MeV. Please consult the factory for custom requirements.

Both models can be fully customized to meet specific requirements. For more information, download the Linatron Mi Datasheet.


Linatron K15

The Linatron K-15 is the ultimate high-energy accelerator for nondestructive testing (NDT) and inspection. With outputs configurable up to 15 MeV, it can penetrate large castings and solid parts. At full output, dose rates can be configured for well over 12,000 rads/min-m. The K-15 is mountable on a fixed surface or yoke. The trunnion mounting feature allows the K-15 to be operated at a variety of orientations to make large object inspection much easier. Linatron M - linear acceleratoK15

The K-15 has a wide variety of optional features to meet specific requirements. The optional filter wheel allows users to remotely select one of four different custom filters. In addition, variable collimators can adjust the beam from four independent axes. The retractable laser sighting tool will identify the precise location of the beam center. For more information, download the Linatron K15 Datasheet.


Linatron Accessories

Varex offers a wide range of accessories to meet most linear accelerator needs. 


Collimators can be attached to Linatron systems along the primary beam path to shape the beam for specific applications. Fixed collimators are circular disks (usually tungsten) with openings that can be cut to the user's specifications. Variable collimators are also available when frequent changes of the beam shape are necessary. 

  • Fixed collimator (specify opening)
  • Variable external collimator with remote control
  • Variable external collimator with rotation

Communication Port Options

Linatron systems are self-contained and do not require communication to external devices for normal operation. However, an optional PC interface can be provided which allows a PC to replace the standard control console. The following communication options are available: 

  • Mod buss
  • Ethernet


Exposure Meter

Radcal 2026 Single Sensor Exposure Meter


Flattening Filters

Flattening filters are circular disks that are a factory-installed option, custom designed based on unique customer requirements—often designed to improve flatness to about 85%. Since a flattening effect occurs by absorbing more dose at the center of the beam, the overall dose rate is typically reduced by about 50%.

Laser Direction Aids

  • Standard laser
  • Dual plane alignment laser


Motorized Tables

Varex can help select a motorized table per your requirements.


Shielding Options

Additional shielding provides greater reduction of leakage radiation, which is defined as radiation outside of a 60-degree cone along the central beam axis.


Spare Parts Kits

Spare parts kits are available for most Linatron systems. These allow system owners to have selected components on-hand that will decrease the repair time for a number of common consumable and limited-life items.

Spot Size

The M9, K9, and K15 are available with small spot size options. Please refer to specific datasheets for the specifications relating to standard spot sizes and the small spot size options.


Temperature Control Units

Varex Linatron systems typically require fluidic cooling with a water/antifreeze mixture at a constant 30 degrees C. Varex provides a number of temperature control units for this purpose.


Voltage Regulators

Varex voltage regulators are optional components used with Linatron systems when the facility power is under-regulated or operating at an incompatible voltage. When needed, these are custom configured for a specific Linatron operating at a specific location. Varex engineers are available to help ensure that the power at a particular site is appropriate for reliable Linatron operation.

The Power Line Conditioner consists of an all copper, multiple tapped, triple shield isolation transformer. The low output impedance of the transformer in conjunction with the electrostatic shields assures precision, hospital-grade performance with excellent noise and transient attenuation. Independently controlled inverse parallel electronic switches for each of the 7 taps per phase provide tight regulation over a wide input range. Linear devices are used for line synchronization to prevent phase shift errors normally associated with simple CT zero current crossing acquisition. The microprocessor control accurately selects the correct tap to maintain the output no greater than +2.5% of nominal with a typical AC input, correcting for voltage disturbances within one cycle. Digital processing technique provides fast and accurate regulation without output voltage over or undershoots.
