CNMC supplies triaxial and coaxial extension cable assemblies in standard 10-meter or custom lengths, terminated with connectors to fit almost any commercially available electrometer/dosimeter and ion chamber.  The CNMC triaxial cable assemblies are made of flexible, white, 3mm diameter, shielded, low-noise, high-impedance, radiation-resistant cable, designed to carry the extremely small currents generated by ion chambers without signal degradation.

Optionally, CNMC can supply the Suhner Swiss grey, 5.34mm diameter triaxial cable found on Nuclear Enterprise Ion Chambers.  Extension cable assemblies can be made to custom lengths in 1 meter increments.  A true extension cable will have a male connector on one end to mate with the electrometer input and a female connector on the other end to mate with the ion chamber output connector.  Other configurations are possible, such as male/male to accommodate the Memorial parallel plate ion chamber, or female/female bulkhead-type connectors for through-the-wall mounting.  Additionally, a wide selection of adapters offers virtually unlimited connector arrangements.

Our Robust Triaxial Ion Chamber Extension Cable is custom manufactured for CNMC specifi cally for its very low noise characteristics and its durability.

This cable is ideally suited for rigorous day-to-day use.  It has a thicker outer insulation layer that makes it less susceptible to cable failures due to mechanical stress from snaking through wall conduit, being stepped on, pinched under a door, or run over by tool carts.

In addition, there is a thicker insulation layer between the center conductor of the cable and the inner shield.  This greatly reduces the effects of inherent cable capacitance, thereby minimizing the effects of internal signal loss and minimizing the effects of extraneous environmental signals.

Robust Triaxial Extension cables are supplied in standard 10-meter lengths and can be custom terminated with connectors to fit almost any commercially available electrometer and ion chamber.  Extension cables greater than 10 meters are available, as are custom cable lengths in 1-meter increments.

CNMC cable reel assemblies offer a great convenience in winding and storage of extension cables.  A cable reel will extend the life of a cable significantly by eliminating kinks and providing protection during storage.  Only as much cable as needed has be reeled out at any time.

A cable reel will accommodate one white Microdot extension cable up to 15 meters in length or two white Microdot extension cables up to 12 meters each.  Either gender may be specified at the hub, depending on whether the cable reel will be kept at the electrometer (male connector at the hub) or inside the treatment room (female connector at the hub).

This ion chamber support stand has been designed to accommodate a wide variety of chambers for in-air measurements.  It is completely collapsible to take up a minimum amount of space inside a carrying case for convenient transportation and storage.

The quick-release clamps allow fast setup and easy adjustment of the ion chamber position relative to the radiation beam.  The sturdy aluminum base provides excellent stability and has adjustable feet to allow leveling on uneven surfaces.
