General Issues

1. General Issues • We will need to understand infrastructure requirements • We will be providing a document to define the laboratory/experiment interface • Possible locations at 4850 level • Davis cavern (interference with LUX?) • Drift adjacent to Yates shaft • New excavation • What are timing requirements?
