2. SR1 ongoing workH.Pernegger21/2/02 Basic Rooms in SR1 Laser Area FSI Test Area All major detector Tests (TRT,SCT) Assembly area Detector assembly small scale tests Rack Area Supply and RO racks Power supplies etc Control Room Air lock

3. SR1 ongoing workH.Pernegger21/2/02 Preparation of main building infrastructure •Present ongoing work on Building related instrastructure: –Installation of metal frame work for cleanroom DONE –Metal frame for control / testarea and laser room DONE –Platform for ventilation DONE –Preparation of rails for installation of duct work and our cables ONGOING –Reduced 1-AHU ventilation system submitted for company estimate DONE •Present work on Detector related infrastructure –Installation of concret slaps in laser room, test area and CMM DONE –Floor preparation ONGOING

4. SR1 ongoing workH.Pernegger21/2/02 Metal Support structures  Support clean room walls, door frames, overhead duct work, …

5. SR1 ongoing workH.Pernegger21/2/02 Clean room metal frame structure DONE

6. SR1 ongoing workH.Pernegger21/2/02 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)

7. SR1 ongoing workH.Pernegger21/2/02 Ventilation system controls Added ventilation platform recently For reduced system

8. SR1 ongoing workH.Pernegger21/2/02 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

9. SR1 ongoing workH.Pernegger21/2/02 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

10. SR1 ongoing workH.Pernegger21/2/02 Platforms •Concrete platform installation DONE Main test support Optical bench In laser area Support for CMM

11. SR1 ongoing workH.Pernegger21/2/02 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

12. SR1 ongoing workH.Pernegger21/2/02 Rack Distribution •Use existing racks from DELPHI (to be refurbished & checked) SCT: 12 LV/HV 3 DAQ 2 DCS 3 panels 2 UPS TRT: 6 LV 2 DAQ 2 DCS PIX: 2 LV 2 DAQ 1 UPS 1 DCS This distribution is a proposal to be verified for functionality

13. SR1 ongoing workH.Pernegger21/2/02 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

14. SR1 ongoing workH.Pernegger21/2/02 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

15. SR1 ongoing workH.Pernegger21/2/02 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.
