%0 Journal Article %T Diagnostics needs for beam-beam studies and optimization %A R. Giachino %J Physics %D 2014 %I arXiv %R 10.5170/CERN-2014-004.189 %X During the recent years of LHC operation, we analysed the situation of beam instrumentation and the need to optimize it for beam-beam studies. The most important beam instrumentation devices will be highlighted and modifications or optimizations will be suggested. A complete wish list will be presented to make sure we will be ready after LS1 (Long Shutdown 1) to study the beam-beam effect in a more complete way. %U http://arxiv.org/abs/1410.3669v1
