IDs at ALBA synchrotron Alternatives for procurement - In house - Conceptual & detailed design - Tendering of blocks and mechanical parts - Assembling (assembling, sorting, shimming) - Outsourced - Conceptual design in house - Tendering of whole ID - Acceptance measurements 4/30 Josep Campmany – CELLS ALBA-SSRF workshop – December 2013
IDs at ALBA synchrotron In-house Benefits • Know-how at home (conceptual and detailed designs and optimization and assembling protocols). Drawbacks • More time and/or personnel is needed. • Training process required. • Assembling process under control • A complete IDs characterization laboratory is mandatory. • Shimming can be repeated up to fulfill requirements • Significative capital costs required for IDs laboratory. • Significative savings in capital costs • Main risk is assumed at home. Benefits Outsourcing Drawbacks • Short time of construction. • Design key points may remain ignored. • No specially qualified technical personnel are required in house. • Assembling and optimization not totally under control. • No risks are assumed in house • Significative capital cost increase. • A complete IDs characterization is not mandatory. • Solve the problems during operation may require external support. 5/30 Josep Campmany – CELLS ALBA-SSRF workshop – December 2013
