Ge detector problematics
Equipment in use:
- Repair of Ge detectors not possible
(e.g. Exogam Ortec)
- Repair not affordable
(e.g. Miniball Eurisys)
AGATA:
- CE monopoly increases costs
- 2nd. source to secure production is missing
DESPEC:
- no affordable source for planar Ge detectors
Future developments:
- knowledge base is fading away
Ge Development and Maintenance Capability
Core task:
- Repair of all kinds of Ge detectors
- Develop novel position sensitive detectors
Wanted side effect:
- Production capability for AGATA, DESPEC, ...
Other possible tasks:
- Develop associated electronics, mechanics,..
- Search for alternative detection materials
.....
What can we do?
Networking:
- Find interested parties
- Discuss ideas, produce solutions
- Identify sites
- Coordinate actions
- Secure support/funding
Start-up:
- Set-up maintenance/development sites
- Initiate Joint Research Activity
- Define specific tasks/actions
- Develop and demonstrate capabilties
.....

Centre Cost and effort
Cost:
- ca. 1M€ for repair/production facility
(Most of required equipment is available, but not in one place)
-> identify equipment, supply to site(s)
-> search for alternatives (commercial implantation, rent a clean room...)
-> find financial sources (repair/development fees, EU, FAIR...)
Effort:
- 3 persons for 3 years learning phase repair/production facility
(maintained permanently, additional personnel for other sites)
- Training opportunities for specialists and next generation
-> supply funds for personnel
-> redirect personnel
