compact cryo-module design for the options of one long cryo-string and of seperated cryo-modules T. Renaglia, V. Parma in progress  
overall layout for above options T. Renaglia tentative solution (all dimensions need iteration) INTEGRATION_SPL 2009-09-15

Decisions taken

  • position of quadrupoles is flexible (centre or beginning of cryo-module), if the position is changed from the beginning of the module to another place the Linac4/SPL transition has to be adapted (03.09.09),
  • in the extraction areas to ISOLDE and EURISOL we assume that warm quadrupoles are used (03.09.09),
  • assume that BPMs can be placed between the quadrupoles of a doublet, whether it is cold or warm (15.09.09)
