Thermo Scientific™ P 211 is designed so that zero neutrons are produced between pulses. Assures that no neutrons are produced between pulses, which is critical for applications measuring neutron die away from the neutron burst.
This product cannot in the foreseeable future be offered for sale due to obsolete components which cannot be obtained. Thermo Fisher Scientific is still able to support existing systems with replacement neutron tubes and most repairs.
The features of P 211 are critical for applications that depend upon measuring the variations of neutron populations following the source burst. The P 211 neutron tube was originally designed by Sandia National Laboratories and incorporates the Sandia-designed “Zetatron” neutron tube.
