Other DESPEC setups
AIDA implantation setup
Coordinator: Tom Davinson
- Stacks of 24cm x 8 cm x 0.1 cm DSSSD (up to 8 detectors in one stack)
- In vacuum inside a chamber still to be defined (a thin Al layer is preferred)
Conditions on the chamber from the point of view of the neutron setup:
The structural materials used for the detector assembly and supporting structures should be as transparent to neutrons as possible. The most critical parts are the vacuum chamber, the supporting frame, the cooling ring and the massive pieces placed close to the DSSSD. They should be as thin as possible and made of neutron transparent materials.
Dangerous materials are: Au (in the contacts and cables), Ag (in the contacts and cables), Sn (for soldering), Cd, stainless steel, Fe, B, Li, Ni, Cu, Br.
Good materials are: Al, carbon-fiber (verify the composition of the resine).
The dead material (supporting frame, cooling frame, massive pieces...) and electronics should be placed as far as possible from the DSSSD in order to minimise the interaction with the neutrons.
