Mössbauer sources with Cobalt-57

Moessbauer

A standard source has Al capsule with 40 μm Al output window. ⁵⁷Co is incorporated into Rh foil (7 μm thickness) by annealing. Rh foil with ⁵⁷Co is hermetically sealed in the capsule by laser welding. The source has ISO classification C 32231 in accordance with international standard ISO 2919.

OPTIONS
Capsule material can be

Ti and 0.5 mm Be window (ISO classification C 54334) or
Al and lavsan (capton) window (ISO classification C 22212).

Matrix material can be Cr, Pd, Pt and Cu.
Dimensions of capsule and active diameter can be modified in accordance with customer request.
