Main remaining General Services work

• Civil Engineering & Infrastructures– Infrastructure at the end of the transfer tunnel– Infrastructure over the wave guides in the tunnel

Linac4

• Electrical systems & cabling– Installation of the electrical boxes in the tunnel at

final position– Pulling of 50 distribution cables for heating

protection of the ionic pumps– Connection of the modulators– Installation of 2-3 missing canalis over the racks in

the hall– Local cabling of the klystrons ongoing

Main remaining General Services work• Cooling and Ventilation

– Cooling pipes in the dump area and for the transfer line– Ventilation system of the control room

• Safety systems– New fire detection system along the modulators in the hall– Use of the access system (PAD/MAD) for 10MeV beam

commissioning (2014)

• Transport and handling systems– New crane in the dump area– Installation of the machine structures/equipment

• Survey– Marking of the diagnostic line, transfer line support– Alignment of the machine structures/equipment

Work baseline for 2013

1. H- source installation & commissioningThe installation planning will be detailed in collaboration with J. Lettry and R. Scrivens. The first solenoid is installed on the LEBT and tests have been performed.March-April-May-June-July-August 2013

2. Hardware commissioning for 3MeVTest procedure for the commissioning of the modulators and the klystrons need to be detailed in order to define the safety aspects and all operational equipment needed.July-August 2013

Work baseline for 2013

3. RFQ and chopper line installationThe installation planning will be detailed in collaboration with C. Rossi. The priority is the installation of the cooling system in the local 400-1-402 in order to install then the klystron of the RFQ.This installation takes into account the installation of the diagnostic line.June-July-August 2013

4. 3MeV beam commissioningThe 3MeV area will be separated by fence and the access will stay possible in the Linac4 and transfer tunnel.From September 2013

In addition• Klystrons & modulators

The installation of the klystrons will continue according to the availability of them.The installation of the modulators will start in the coming weeks with the RFQ modulator and will continue during the year according to their availability.

• Linac4 machine installationIt would be possible to install some CCDTL according to the installation readiness planning of the structures and the availability of the jacks.

• Open DaysThe Linac4 will be one of the visiting site at CERN.27-28-29-30 September 2013

Concerns

In March 2014 is foreseen the beam commissioning at 10MeV. According to the safety requirements, the access system will need to be operational and the ventilation need to run at nominal conditions.

– The tunnel need to be hermetic:• The material shaft need to be closed• Do we need to make the services shaft airtight ?

BIG thanks to

Everyone involved in the Linac4 installation for their good collaboration and great job done

– CERN staff– Firms (Ineo, Ineo Cofely, EMTE, Spie, Scrasa, Iniziative, Cegelec, MZ, Soteb,

Ouvaroff …)– Coordination on site (E. Paulat, J. Etheridge, A. Masson, G. Pastor)… and all those I might forgot !

The installation of Linac4 has a good progress and the first phase of General Services was completed successfully. Everything is ready for the machine

installation.

THANKS FOR YOUR ATTENTION
