Mössbauer sources with 57Co
- A standard source has a capsule from Al with an output window of 40 µm Al foil. 57Co is incorporated into Rh foil matrix (7 µm thick) by annealing. The Rh foil with 57Co is sealed hermetically in the capsule by laser welding. The source has ISO classification C 32231 in accordance with international standard ISO 2919.
- OPTIONS
The capsule can be fabricated upon request as follows:
- Ti and 0.5 mm Be window (ISO classification C 54334) or
- A1 and capton window (ISO classification C 22221).
The capsule dimensions and active diameter can be modified as specified by the customer.
