The DESIR collaboration has submitted a Letter of Intent to the SPIRAL2 Scientific Advisory Committee in 2006, where the construction of a low-energy facility at SPIRAL2 was proposed. The LOI contains the Physics case of DESIR, the layout of the facility, a cost estiamte as well as a list of the co-authors. This Letter of Intent does not present the possibilities offered by reaction products, as this option was added to the physics case of DESIR and S3 later.
The short version of the LOI can be download here .
A much longer version of the LOI is also available.
