Gas-filled neutron tubes
Types of neutron tubes: Zh83-R2044 (Ж83-Р2044); AREV-40 (АРЕВ-40) and AREV-28 (АРЕВ-28).
Production cycle of pulsed neutron technologies is carried out starting from «zero» point – development and manufacturing of high-frequency gas-filled neutron tubes (trade name – AREV (АРЕВ)). Tube development is based on the world latest engineering and technological achievements. For example, component parts of AREV (АРЕВ) neutron tubes are manufactured according to the documentation of RPE Energiya, LLC (ООО «НПП Энергия») at the enterprises in 6 different countries.
Manufactured parts are supplied to FSUE Integrated Plant “Electrohimpribor” (ФГУП «Комбинат «Электрохимприбор»), where neutron tubes are assembled according to the jointly developed technology. According to the documentation of RPE Energiya, LLC (ООО «НПП Энергия») 2 types of gas-filled neutron tubes AREV-40 (АРЕВ-40) and AREV-28 (АРЕВ-28) with maximum diameter of 40 mm and 28 mm respectively and previously developed tube Zh83-R2044 (Ж83-Р2044) are manufactured in series at FSUE Integrated Plant “Electrohimpribor” (ФГУП «Комбинат «Электрохимприбор»).
Tube «acceleration» is carried out on the scientific and production facility. Pulsed neutron generators based on the tubes of AREV (АРЕВ) and Zh83-R2044 (Ж83-Р2044) series are also developed and manufactured there. AREV (АРЕВ) tube bulb is made of ceramics, current-focusing electrode structure does not have open-ended elements.
Therefore AREV (АРЕВ) tubes have outstanding resistance to vibration and impact effects. Parts’ manufacturing quality and assembly technology ensure maximum structure concentricity.
