ASTM E1855-10<\/h3>\n

Historical Standard: Standard Test Method for Use of 2N2222A Silicon Bipolar Transistors as Neutron Spectrum Sensors and Displacement Damage Monitors<\/h4>\n
\n

ASTM E1855<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the use of 2N2222A silicon bipolar transistors as dosimetry sensors in the determination of neutron energy spectra, and as silicon 1-MeV(Si) equivalent displacement damage fluence monitors.<\/p>\n

1.2 The neutron displacement damage is especially valuable as a neutron spectrum sensor in the range 0.1 to 2.0 MeV when fission foils are not available. It has been applied in the fluence range between 2 \u00d7<\/span> 10 12<\/sup> n\/cm2<\/sup> and 1 \u00d7<\/span> 1014<\/sup> n\/cm2<\/sup> and should be useful up to 1015<\/sup> n\/cm2<\/sup>. This test method details the steps for the acquisition and use of silicon 1-MeV equivalent fluence information (in a manner similar to the use of activation foil data) for the determination of neutron spectra.<\/p>\n

1.3 In addition, this sensor can provide important confirmation of neutron spectra determined with other sensors, and yields a direct measurement of the silicon 1-MeV fluence by the transfer technique.<\/p>\n

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.<\/span><\/p>\n
