Preparations for CO2 Systems at DESY
6
Following the proposal made at dedicated MARCO meeting at MPI (March 1st) three CO2 systems are in preparation at DESY- 2 systems foreseen for Belle II (too be agreed)
- 1 test system for ATLAS/CMS phase II upgrade studiesRequired overall cooling capacity mainly determines chiller parameters - work out concept of load balancing between SVD and PXD cooling circuits‣ here we need realistic input on heat loads / losses / loop configurations (SVD & PXD)
‣ define diameter and length of cooling pipes & capillaries
CO2 part of IBBelle probably very similar to MARCO

Pros- mechanically quite flexible- integrated N2 pipe
=> number of lines can be reduced
Cons- all pipes have same
diameter- N2 and CO2 temperature
not independent
Pros- N2 and CO2 temperature
can be chosen independently
- return line has larger cross section
Cons- stiff

What are realistic assumptions for Tcb and Tenv?How important is it to be able to independently choose TCO2 and Tgas?

Remote Vacuum Connection
12
First ideas presented by K. Gadow on June 1st- several discussions with KEK vacuum experts leading to small modifications of the design
Decision to build mock-up at DESY taken on June 26th - production of parts in DESY central workshop has started- aim to have first results ~ by end of August / beginning of September
[email protected] B2GM • Bad Aibling • 23.07.12 • Cooling/Mockups
SummaryWork on thermal mock-up progressing well albeit with some delay- have to bring XFEL cooler into operation- finalize mock-up and connect to XFEL cooler to get some first experience
In parallel preparations to build CO2 cooling systems for Belle II are ongoing at DESY- soon have to agree on exact specifications
‣ CO2 part
‣ Chiller
Components for remote vacuum connection mock-up are being produced in DESY workshop- first results with mock-up expected ~ end of August / mid September
