Abstract
An inorganic vitreous detector material which in principle is composed of the three-component system consisting of metaphosphoric acid, aluminum metaphosphate, and zinc oxide, is used for the determination of the energy of particles of high energy. Such a material may additionally contain silicon dioxide and boron trioxide.
Claims4
An inorganic vitreous detector material having the properties of excellent energy resolution for impinging heavy ions and fission products, a high dependence of specific hole diameter with respect to impinging particle energy and as being substantially insensitive to background electrons and gamma-rays, said material consisting essentially of:
- a. silicon dioxide SiO.sub.2 and boron trioxide B.sub.2 O.sub.3 in an amount not exceeding about 10% by weight;
- and
- b. the balance, a three-component basic system consisting essentially of metaphosphoric acid, aluminum metaphosphate and zinc oxide within the following concentration limits:
- about 20 to 60% by weight of metaphosphoric acid HPO.sub.3,
- about 30 to 80% by weight of aluminum metaphosphate Al(PO.sub.3).sub.3, and
- about 2 to 30% by weight of zinc oxide ZnO.
