2/3 rack groups: are they needed? Alternative 3/3 cabinets. Is it possible? Pros and Contras
Preferably 3-Rack unit rather than 2-rack unit because of the lower costs (pro rack!). Costs difference must be checked
Preferable to locate the water distribution upstream of klystron. Is it possible?
Preferable to locate the LLRF between 1&2 and 3&4 module to guaranty the same cables length
Are there any power constrains: 700W connection power and 8kW maximum power dissipation
There are still some doubts that all "motors" are considered or on the contrary twice included
Can the stepper motor drivers been combined in one rack (which)?
Cable routing of motor driver is unclear
To be clarified if racks can be located near the Schiebemove
Before you start editing the slides of your talk change to the Master Slide view: Menu button “View”, Master, Slide Master:

If you want to use more partner logos position them left beside the DESY logo in the footer area Close Master View
