An in-depth, if somewhat outdated, description of the experiment motivations, method and of the intended detector setup was produced back in 1991, when we submitted our proposal to the SPS committee. This is available both as a 6 MB compressed postscript file or as a pdf file (you'll need the Adobe Acrobat Reader to read it)
The interested reader is referred to the list of NA48 papers and conference contributions.
