TAS-Q1 – vacuum equipment design
Lukasz Krzempek 01.09.2015 1 TE-VSC-DLM
General view of 3d conceptual design (ATLAS&CMS) 1) Created solution is a baseline of current vacuum system 2) Where possible – aluminium solution (transition)3) BPMSW4) 3 structures to remove independently: gate valve TAS, VAX+BPM, gate valve IR5) Long bellows to transfer transversal & longitudinal while short ones -
longitudinal
TAS
Experiment
Alignment issues
Sector valve moves with TAS absorber
Sector valve moves with vacuum chamber
VAX+BPM movesindependentlyPumping/venting lines
together with angle valve on site
Tunnel

Angle valves integrated as close VAX body as possible
Chain for quick disconnection DN40

Height:740mm
Bellow: aluminiumBellow’s connections: stainless steel
In work connection of angle valves with vax body

Groove for compressing/extension mechanism
250mm – free length270mm – installation length
Design based on Stainless steel standard solution

Conceptual compressing/extending model
In 3d design:20mm distance left for ‘bellow installation length’
Going to aluminium bellows, stretching is even more preferable then compressing (to be further checked)
Cabling/piping management (thermocouples + heating power) - proposal

Cabling management (1)
Lukasz Krzempek 01.09.2015 6 TE-VSC-DLM
Nomenclature:Tce: thermocouple type EVEC: heating collarVET: heating tape + insulation thickness 8mmVEJ: heating jacket + insulation thickness 25mm
Calculated section: 1055mm2
Ion pump cable assumption ~D1cm
Total: 1200mm2

Cabling/piping management (2)
Lukasz Krzempek 01.09.2015 7 TE-VSC-DLM
Outside diameters:1. Flange DN63 + heating collar OD114+3 thickness (mm)= OD120 (mm) ~140 (mm)
2. Tube DN63 + heating tape + insulation OD63+tape+8 thickness (mm)=83 (mm) ~100 (mm)
3. Bellow + heating tape + insulation OD83 + tape + 8/25 (mm) = 103/135 (mm) ~120/150 (mm)
The rest of pumping/ venting instruments depends on design
