New building: preliminary design

COLLABORATION BETWEEN:

INTEGRATED DESIGN CONCEPTS integrated design of building and systems, pursuing the following goals:

• functionality• flexibility• space efficiency• sustainability• cost efficiency• life quality

Multidisciplinary design team: infrastructures (civil works, plants, safety, radioprotection…) and accelerator physics team study and analyze together the requirements and constraints throughout all the design phases.

The expected outcome will be achieved by a continuum feedback between the stakeholders.

Urban planning guideline

Standards Maximum buildable area: 5.418 m2

Maximum building volume: 53.330 m3

Maximum height of the building: 12 m

Frascati area is bounded by archaeological and environmental restrictions, as defined by the Piano Territoriale Paesistico Regionale of Lazio region.

We must follow a defined procedure to obtain the Authorization for Construction Permit.

Slab stability against ground vibration and seismicity of the site

A campaign of detailed ground motion measurements in LNF was performed for the SuperB project

For reference, following table summarizes the acceptable tolerance defined for Soleil Synchrotron (France):

The soil consist of volcanic products, with a good degree of stability. The survey was done to a depth of about 37 m.

layer of vegetable soil and fill material (about 1 to 3 m); Brown pyroclastic grounds (5 to 7 m layer); Lava rocks (1 to 2 m, max 4 m); Other layers of grey pyroclastic material, including pockets of scoria, lava tuff

elements.

From a seismic point of view, the site is classified 2B seismic area

The site is able to support heavy loads and to damp vibrations coming from natural sources and cultural noise.

The design is based on LNF Know-How and European best practices.

Fluids plants will be divided in:

De-ionized water cooling plant for electromagnets and RF systems,

Refrigeration plant to supply AHUs;

HVAC plant for accelerator area and ancillary rooms conditioning and radiation safety issues;

Technical gas and compressed air plants.

An auxiliary plants supervision and control system will assure the highest possible up-time and to reduce MTBF helping in fault diagnosis.

Energy efficiency and sustainability also drive plants design.

Preliminary design _ Fluids plants

In detail, for HVAC plant:

The temperature set will be the same for all seasons to stabilize the machine operational condition.

Particular attention will be paid to temperature stability in the critical rooms (lasers, ondulators...).

Electrical Power

• Eupraxia@SPARCLab will be fed by the LNF 150/20 kV proprietary substation.

• A dedicated MV substation inside the building is equipped with 2 transformers 20/0,4 kV 1,6 MVA sized (3rd transformer ready).

• The LV switchboard is transformer fault tolerant.

Main items: Lighting; Power distribution; Electrical Switchboards; Bus-bar power distribution, aimed to the maximum flexibility of the loads in the

technical areas; HVAC and cooling system powering; Common Bonding Network for EMC issues; Phone, to be integrated in the labs system; Electrical system control and supervision to be integrated into the existing one .

Main issues taken into account:• Availability and continuity• Non linear and unbalanced loads: modulator are extremely noisy loads on the network

to be compensate• Electromagnetic compatibility • Voltage dip compensating system
