Improved multichannel neutron polarizers on basis of CoFeV/TiZr supermirrors with TiZrGd underlayer

Improved multichannel neutron polarizers on basis of CoFeV/TiZr supermirrors with TiZrGd underlayer

Measurements of the polarizing efficiency and transmittance of a new high-efficiency multichannel neutron polarizer are presented. The procedure of the measurements is given. The parameters of new Fe 30Co 68V 2/Ti 75Zr 25 supermirrors and a polarizer made of them are compared with old Fe 34Co 64V 2/...

Zusammenfassung:Measurements of the polarizing efficiency and transmittance of a new high-efficiency multichannel neutron polarizer are presented. The procedure of the measurements is given. The parameters of new Fe 30Co 68V 2/Ti 75Zr 25 supermirrors and a polarizer made of them are compared with old Fe 34Co 64V 2/Ti 60Zr 40 supermirrors and an old polarizer. We discuss how the polarizing efficiency of the coating was improved.
