Abstract

Нейтронний сцинтиляторний композит (NSC) вироблений з нейтронного сцинтилятора і в'яжучого, що має формулу LiyMgBry+2, де у=2, 4 або 6 і може надалі містити церій як сцинтиляційний активатор. В'яжуче композиту має індекс рефракції по суті ідентичний індексу рефракції нейтронного сцинтилятора. Нейтронний сцинтилятор і в'яжуче змішуються у твердий або напівтвердий нейтронний сцинтиляторний композит, який має суттєву пластичність для формування у сформований виріб, такий як нейтронно-чутливий елемент або радіаційний детектор. Нейтронний сцинтиляторний композит збирає і направляє фотони через власний матеріал до фоточутливого елемента, який оптично під'єднаний до композиту. Через те, що індекси рефракції нейтронного сцинтилятора та в'яжучого є по суті ідентичними, розсіювання на границі(ях) сцинтилятор-в'яжуче є мінімізованим, і, таким чином, отримана ефективність передачі досягає ефективності монокристалів.
