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

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

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

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
