NPL2611A Ion Chamber
The NPL2611A is a Secondary Standard Therapy Dosimetry Chamber produced by the National Physics Laboratory.

Construction of the NPL2611A chamber consists of a thin walled high purity graphite thimble, amber insulator and a hollow pure aluminum electrode and is supported by a thin walled aluminum stem. The stem terminates in a robust cable entry, by which the chamber can be mounted.  A length of low noise triaxial cable connects to a TNC triaxial plug.  Since the chamber is vented, air density corrections must be applied.
Please note: This chamber is manufactured at the National Physical Laboratory (NPL), in the UK, and support, both in terms of maintenance and calibration, are available from NPL directly.
Serving the External Dosimetry, Radiation Detection, and Spectroscopy communities since 2012.
