Remarks & Questions on Lucasz concept
Feedback on LHCb cooling reviewB. Verlaat, EP-DT-FS11 February 2016
Slide2Remarks:On the current P&ID, there is no way to pressurize the detector from the LUCASZ
plant to do a leak check for example. On this point the design of Lucasz has been changed (LUCASZ lite
)
On the 3D it seems there is pipe above the motor of the pump, think about the maintenanceOn this point the design of Lucasz has been changed (LUCASZ lite)We would not remove the ‘’service components”.The service components need to be discussed, as it is a matter of budget, maybe a manual version is possibleExperience in CMS has shown that the concept of including a cold box in the cooling plant has numerous well appreciated advantages. It would be good if this can also be implemented in the VELO plant design.A foam construction was chosen because of budget.The design of the frame looks very light considering that LEWA pumps generate vibrations. Frames should be rather rigid to avoid resonance. On this point the design of Lucasz has been changed (LUCASZ lite)The design does not look like it is optimised. More compact seems possible.LUCASZ lite has implemented this

Slide3Remarks & Questions on LUCASZ concept
Remarks:A good trade-off study between safety valves and burst disks should be performed. Safety valves often leak, burst disks require higher system pressures.The system already has the absolute minimum of safety valves.
Questions:
Is there compressed air in the assembly area?The new Lucas-lite design has no air3
