Exradin® A10
Plane-Parallel Ion Chamber
The Exradin® A10 is a vented, waterproof, plane-parallel ionization chamber designed specifically
for the dosimetry of electrons with energies above 100keV, according to the Bragg-Gray principle.
The Exradin® A10 design is similar to the Markus® chamber, having the same
external dimensions that allow it to fit into existing solid phantom cavities made for the
Markus® chamber. The collector diameter and electrode gap
are the same as found in the Markus®, therefore the
collecting volume and calibration factor will be very similar.
A significant improvement was made
in the width of the guard ring that greatly reduces perturbation and polarity effects. The electrode
materials are made of conductive plastics for electrical continuity, eliminating troublesome
conductive coatings.
The Exradin® A10 can be operated submerged in water with the waterproofing/calibration cover attached.
The chamber is supplied with your choice of connectors and has a handsome, padded wooden case.
