In the Optics 1.5 the crab position in the layout has been reviewed in order to take into account the design constraints of the cryogenic distribution line (QXL). In addition, the new approach guarantees the accessibility of the QXL equipment (valves and instrumentation) and provides an identical cryogenic layout able to receive both RFD and DQW cryo-modules that will have different lengths. The compensation will be performed by the horizontal extension that will connect the farthest (from the IP) jumper with the farthest cryo-module. This element will be 501 mm longer for the DQW Crab Cavity module compared to the case where an RFD Crab Cavity is installed. This solution will enable possible exchange of the crab cavity types between IP1 and IP5 in LS4 or later, hence making possible to change the crossing plane in the two main experiments.
