Californium neutron flux multiplier

Kaliforniy neytron oqimi multiplikatori

Kaliforniy neytron oqimi multiplikatori (CFX) — tadqiqot maqsadlarida neytronlar manbai hisoblanadi. U neytronlar hosil qilish uchun oz miqdorda kaliforniy-252 va subkritik konfiguratsiyada joylashtirilgan yuqori darajada boyitilgan uran (uranium-235)ning bir nechta plastinalaridan iborat. Kaliforniy spontan yadro parchalanishiga uchraganda neytronlar chiqaradi, ular uranga urilib, uning ham parchalanishiga sabab bo‘ladi va natijada yana ko‘proq neytronlar ajralib chiqadi. Ushbu induksiyalangan bo‘linish kaskadi turli tasvirlash va tahliliy usullarda qo‘llanilishi mumkin bo‘lgan neytronlar oqimini hosil qiladi. Neytronlarni olish uchun faqat katta miqdordagi kaliforniyga tayanish o‘rniga, atigi bir necha milligramm ²⁵²Cf tomonidan ishga tushirilgan 3,5 funt uranning multiplikator ta’siri kamroq xarajat evaziga yakuniy neytron oqimining yuqoriroq bo‘lishini ta’minlagan.

CFX IRT Corporation tomonidan loyihalashtirilgan,^[1] va ikkita qurilma ishlab chiqarilgan. Birinchisi 1975-yilda Eastman Kodak kompaniyasining Rochester, New Yorkdagi inshootiga o‘rnatilgan va 2006–2007-yillarda foydalanishdan chiqarilgan. Ikkinchisi US Department of Energyning Ohayodagi Mound Laboratories inshootiga o‘rnatilgan va oxir-oqibat 1990-yillarda foydalanishdan chiqarilgan^[2].

Kodak o‘z qurilmasidan neytron-aktivatsion tahlil va neytron radiografiyasi uchun foydalangan.
