CERN Conseil Europeen Recherche Nucléaire - European Organisation for Nuclear Research Biggest physics laboratory in the world founded in 1954 by 12 European States Today: 22 Member States ~ 2300 staff ~ 1400 other paid personnel ~ scientific users Budget ~1100 MCHF 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

CERN What do we do? How do we do it? Fundamental research in particle physics: Constituents of matter (and forces) Origin and Structure of the Universe Many questions remain: what is dark matter, what happened in the big bang, what happened to anti-matter… Accelerators: Put lots of energy into particles Colliders: Turn energy into matter: E = mc2 Detectors: Identify and measure particles Computers: Analyse and understand what happened Infer the properties of the parent (heavy) particles 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

CERN Accelerators CERN has many different accelerators The biggest one is the Large Hadron Collider, which is 27 km long ATLAS, ALICE, CMS and LHCb are the four main experiments along LHC The beams collide 40 million times per second in the four points 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Large Hadron Collider (LHC)
The LHC is the most powerful instrument ever built to investigate particle properties Four gigantic underground caverns to host the huge detectors The highest energy of any accelerator in the world The most intense beams of colliding particles It operates at a temperature colder than outer space 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

ATLAS ATLAS is about 45 m long, more than 25 m high, and weighs about 7,000 tons. (about half as big as the Notre Dame Cathedral in Paris and weighs the same as the Eiffel Tower) It has an onion-like structure: many layers of different materials make up different sub-detectors and each layer has a cylindrical part and a disk-like part at both ends of the cylinder in order to cover all regions of space. 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

ITk Pixel detector Strip detector Inner Tracker The ATLAS Inner Detector combines high-resolution detectors at the inner radii with continuous tracking elements at the outer radii The entire tracking system of the ATLAS experiment will be replaced during the LHC Phase II shutdown (foreseen to take place around 2025) by an all-silicon detector called the ITk (Inner Tracker). 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Schematic layout needs
Present layout Future layout R-202 shall be extended R-C04 shall be divided into two separate rooms: R-C04-A (not a cleanroom) and R-C04-B (cleanroom) R-C04-B shall be extended and sealed 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Scope of the supply The contractor shall design, supply, install, test and commission the modification of the current cleanroom extension. The supply consists of: Works to be executed Replacement of the existing ceiling (if requested) Supply and installation of lighting for the cleanroom extension ceiling (if requested) Supply and installation of lighting for the existing portion of the cleanroom (if requested) 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Works to be executed In orange is shown what it is surely requested by CERN for this supply 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Starting layout Radiation lab Existing Changing room Existing cleanroom Material lobby Building extension This is the layout the contractor will find at the beginning of the their work (January 2018) 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Internal partitioning walls
Test area Radiation lab Extended Changing room Existing cleanroom Material lobby Building extension The first step is to install the partitioning walls, isolating the cleanroom 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Internal envelope walls
Test area Radiation lab Extended Changing room Extended cleanroom Material lobby Building extension Eventually the rest of the internal envelope walls shall be added 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Changing room (corridor) extension
The changing room has to be extended over the cable trays, so that they will be out of the cleanroom. It shall have two single doors: one to enter R-C04-A and one to enter R-C04-B. Its ceiling shall continue the existing one. The dismantling and disposal of existing door (and wall) of the current changing room is part of the supply. 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Internal partitioning wall
The internal partitioning wall shall have two windows and one double door. It shall be extended up to the ceiling and sealed (airtight) in order to completely separate R-C04-A from R-C04-B. It shall have the openings for cable trays and all other openings requested by CERN. 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Enclosures (pillars and cable trays)
Enclosures for pillars Enclosure for cable trays Each pillar shall be enclosed and sealed. The enclosure shall have openings on two opposite sides to access the cable trays running along the pillars as well as opening for electric and Ethernet sockets, switches, etc. The cable trays will run along the upper corners of the cleanroom (see next slide) and shall be enclosed and sealed. The enclosure shall have openings to access the cable trays and allow an easy cable pulling. 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Enclosures (pillars and cable trays)
Enclosures (and cable trays) shall be located according to this picture. No enclosures/cable trays shall be added over the rails (the height of the room is important in this area) 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Double door View from inside View from outside The double door on the North-East side of the extension shall be airtight (rails to be considered). It shall have transparent windows (not shown in the figures). It is always in direct contact with the external environment (removable wall is not sealed). Once opened, it shall guarantee an opening of at least 2800mm x 3500mm  it shall be opened towards the inside. 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Extension walls The extension walls shall arrive up to the ceiling and shall be sealed and airtight. They shall have the openings for the CV grids, for the grounding, for sockets (electric and Ethernet), switches and all other openings requested by CERN. Dimensions of the sandwich panels shall be adequate to the environment constraints (access doors, scaffolding, etc.). The metallic structure can be either “stand-alone” or added to the existing structure. 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Extension walls This is the foreseen position for electric boxes (sockets), where there will be the need of dedicated openings 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Extension ceiling If the existing ceiling is not replaced, the extension ceiling shall be at the same height of the existing one. It shall be walkable and airtight. Its supporting structure can be either “stand-alone” or added to the existing structure (preferable). If CERN will choose to take care of the lighting, the extension ceiling shall have the openings for the lighting units. The number, dimensions and location of these openings will be communicated by CERN. The ceiling shall be safely accessible (ladder and platform over the existing non-walkable ceiling are part of the supply). 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Replacement of the existing ceiling
IF REQUESTED In addition to the “Works to be executed”, CERN can request also the replacement of the existing ceiling  dismounting and disposal of existing panels and lighting units + installation of new walkable ceiling 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Replacement of the existing ceiling
The new ceiling in the existing portion shall be below the existing structure (currently it is above the structure). It shall be walkable and airtight. Its minimum height shall be 3700mm. Its supporting structure can be either “stand-alone” or added to the existing structure (preferable). If CERN will choose to take care of the lighting, the ceiling shall have the openings for the lighting units. The number, dimensions and location of these openings will be communicated by CERN. Also in this case, the extension ceiling shall be at the same height of the existing one. The ceiling shall be safely accessible (access ladder is part of the supply). 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Lighting CERN might order also the supply and installation of (either one or both) lighting units for: Lighting for the cleanroom extension ceiling Lighting for the existing portion of the cleanroom IF REQUESTED IF REQUESTED Lighting units shall be LED type. They shall be embedded into the ceiling panels. Minimum overall illumination of at least 400 lux with a uniformity ratio of 0.7 at 1 m from the floor. Number, dimensions and location of ceiling openings is decided by the contractor. 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti

Sealing, testing and Commissioning
Once all the other WPs completed their works, the contractor shall perform a sealing campaign in order to close all openings present both in the newly installed items (walls, doors, windows, ceilings, enclosures, etc.) and in the existing ones. Only after the sealing is complete, the contractor shall perform the final airtightness test (smoke test or equivalent). The contractor shall consider to perform this test in a separate further session. The commissioning will take place only when all tests show compliance with the Technical Specification 03/10/17 SR1 cleanroom extension Bidders' conference Marco Ciapetti
