Ventilation system

First version of ventilation system based on 4 air handling units too expensive

Redesigned ventilation system including all duct-work, duct work routing based on a system with 1 AHU which provides Started 7. Jan. Clean room ventilation (approx. class 100k) Ventilation to rack area, control room, laser Partial rack cooling (low power racks)

Submitted to bidding companies (end of January) Expect answers from companies soon (no firm cost numbers yet, use

cost estimates to ID below) Ventilation system is a combination of several orders

Basic Air handling unit and ventilation system approx 500kCHF Control system Primary cooling Smoke detection Oxygen deficiency monitors Totals to approx. 600kCHF (to be confirmed)

Preparation of rail system under false floor

Require clearing some areas for installation of duct work of ventilation system

Use existing rails under false floor for routing and support of services (cables, fibres, etc) to assembly area

Detector macro assembly related preparations

Working at present on general detector related items Items are shared partially between sub systems

Rack distribution and sharing in rack room Gas Distribution Location of services outlets in test area and assembly area Floor Feed through in outer building wall Network connection

SR1 ongoing work H.Pernegger 21/2/02

Floor All floor based on existing floor with max. load 500kg/m2 Based on panels 60x90cm2 Floor in clean area to be covered with anti-static sheet Part of assembly area needs to be reinforced for heavy items

(max. load 2000kg/m2) Two options studied at present with (a) reinforced panels (b)

support rails under existing floor

SR1 ongoing work H.Pernegger 21/2/02

Rack Distribution Use existing racks from DELPHI (to be refurbished & checked)

SCT:12 LV/HV3 DAQ2 DCS3 panels2 UPSTRT:6 LV2 DAQ2 DCSPIX:2 LV2 DAQ1 UPS1 DCS

This distribution is a proposal to be verified for functionality

SR1 ongoing work H.Pernegger 21/2/02

Services outlets in clean area

All main supply/DAQ is located in rack area Foresee several different location for services outlets in

assembly & test area

SR1 ongoing work H.Pernegger 21/2/02

Gas distribution

Detector,environmental gas and leak tests (CO2,He) installed as technical gallery along full clean room along with compressed air

Defined location for inlets on outer walls, distribution & extraction still to be looked at

SR1 ongoing work H.Pernegger 21/2/02

Time schedule (estimate)

Order of ventilation determines time schedule Assume

Order placed by mid March Delivery time for ventilation components approx. 2mo. , prepare

during this time installation drawings for duct work Start ventilation installation by mid May. Total time estimate (to be confirmed) approx. 4 months Installation of clean room walls several weeks after ventilation

starts Installation finishes by mid Sept.

Installation of detector related parts during this period (summer?) need to be coordinated with ST.
