Although most existing ALS beamlines will remain as part of the upgraded facility, the ALS-U Project will include a small number of new and rebuilt beamlines. The selection criteria for determining these beamlines are:
- Scientific importance
- Relevance of ALS-U characteristics and potential world leadership
- Technical feasibility and fit to project resources
- Strength of the relevant user community and expected productivity
Community input on potential new and upgraded beamlines was solicited until early 2018. A working group consisting of ALS staff and Users’ Executive Committee (UEC) leadership has synthesized this input into a series of possible scenarios that are being evaluated by external advisory committees, which will then make a recommendation to the ALS-U project director.
