Research of Radioisotope Production with Fast Neutrons, (III)

MSGC test with fast neutrons

Results are presented from the exposure of a CMS performance prototype MSGC to a fast neutron beam having an average energy of 20 MeV and an intensity of 7 106 neutrons/mm2/s. A fluence equivalent to 3 years of LHC operation has been accumulated without damages to the detector. The stability of the MSGC operation in a heavily ionising particle flux is reported and the estimation of their produc...

Zn Radioisotope Production by Cyclotron

Natural Cu target was irradiated with proton beam in the energy range of 15 to 30 MeV at a beam current of 100 μA for 15 min. In this irradiation radioisotope of 62Zn was produced as a generator and then decayed to Cu radioisotope. The Cu is emitting β+ and known as PET radioisotope. Excitation function of Cu via Cu (p, 2n) Zn, Cu and Cu (d, 3n) Zn reactions were calculated using Alice and Taly...

Materials Research With Neutrons at NIST

The NIST Materials Science and Engineering Laboratory works with industry, standards bodies, universities, and other government laboratories to improve the nation's measurements and standards infrastructure for materials. An increasingly important component of this effort is carried out at the NIST Center for Neutron Research (NCNR), at present the most productive center of its kind in the Unit...

Neutrons for Research

Effects of fast neutrons on the eye.

The study of 93 eyes receiving neutron irradiation establishes the character of the ophthalmic complications of neutron. Significant changes are produced in the eyelids, conjunctiva, and cornea, but the production of cataract is relatively unimportant. No reaction was seen after neutron treatment that had not already been seen after chi or gamma radiation. That the unavoidable damage is similar...
