Goal: An easy to (mass) produce user friendly system • operational from +250C to -400C • cooling power up to 350 Watt
Transportable Refrigeration Apparatus for CO2 Investigation

Visit by NIKHEF experts end of June Check function of XFEL cooler - found that CO2 flow is factor 3-4 too small
Next steps - replace filter - if this does not help have to replace pump head
Status XFEL Cooler

5. WARNING PAGE: FILTER CHECK The quality of the filter can be checked at a cooling temperature of -10°C and a sub cooling temperature -20°C while the mass flow runs via the bypass. Table 1 gives the mass flow as a function of the rotational speed of the pump when the filter must be replaced (Low limit) and the mass flow as a function of the rotational speed of the pump with a new filter (High limit).

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 studies Required 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

manifold to split CO into separate lines (diameter mm each): forward: for PXD, for SVD, length .m
backward: for PXD, for SVD, length .m valves foreseen to be able to steer/stop ow on dierent lines transition foam isolated→ vacuum isolated in addition, we need lines for dry nitrogen (diameter mm each):
forward: for PXD, for SVD, length .m backward: for PXD, for SVD, length .m
Karl-Heinz Ackermann, Christian Kiesling, Martin Ritter Update PXD Mechanics, Status of MARCO
p
l =
8
=> number of lines can be reduced
Cons - all pipes have same
diameter - N2 and CO2 temperature
not independent
can be chosen independently
Cons - stiff

What are realistic assumptions for Tcb and Tenv? How important is it to be able to independently choose TCO2 and Tgas?
Thermal Simulations
Tcb = -20 ºC Tenv = -15 ºC

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
Summary Work 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
