ADU project

• Design Report for the end of 2012 with clear costing and schedule & initial prototyping• Readiness to construct by the end of 2012 -- all requirement

and interface documents and lay-out drawings ready• Energy budget and sustainability should be taken into

account in each work package• Milestone end of 2011: New baseline and first version of

design report

• Responsibilities within Management team• S.Peggs – Communication• R. Duperrier – System engineering• C.Oyon – Internal review• M. Lindroos – Project leader

Prototypes

• Planned and proposed prototypes in ADU project (before 2013):– SC Cavities (High beta elliptical and spoke types) at CEA and IPNO– Tests with existing ion source and RFQ (under assembly) in Catania and at CEA– Test of ITER type control system HW unit with SW interface (“Control box”)– First beam instrumentation in Lund

• Planned and proposed prototypes in P2B project– RF source, control and distribution system in Uppsala– Discussions with RRCAT in India on the construction of a low beta elliptical cavity prototype

with the aim of building these cavities in India as an Indian in-kind contribution to ESS– Discussions with JLAB for a additional spoke cavity prototype built in the USA– Half length cryomodule for 4 elliptical cavities with CERN– Full length cryomodules for all SC cavity types– Beam instrumentation– Final version of Ion source in Catania– DTL at INFN– All ESS beam instrumentation in Lund

First simulation results

Test stand strategy

• 704 MHz test stand for SC elliptical cavities and a cryomodule– ESS is contributing with a modulator to the CERN test-stand– Study and costing in progress for CERN, CEA and Uppsala test stands– Focus in Uppsala on RF source, control and distribution (energy

aspects)– Study of the possibility to use the XFEL infrastructure and test stands

at DESY and CEA for ESS construction

• 352 MHz test stand for SC spoke cavities and cryomodules– One test stand at CEA for NC structures– One test stand under construction at IPNO in Paris

• Test area for Ion Source development exists in Catania

Test cryostat

Upgrades

• The mandate is to build a 5 MW accelerator!• The presently favored upgrade scenario is a power

upgrade to higher power with maintained time structure

• We will study how this can be prepared within the present 5 MW baseline– The additional cost should be understood and

made apparent in the costing of the 5 MW baseline

– First technical studies and financial estimates for the upgrade itself should be done as part of the ADU project

Conclusions>We will build the ESS in Lund and with all the

others in the ESS program deliver first protons before the end of the decade

>The Accelerator Design will permit a long life with many upgrades

>The Accelerator design, prototyping and construction will be done in a collaboration with ESS AB in Lund as coordinator and future owner

>The energy aspects of the accelerator complex are very important

>Many Thanks to all members of the emerging ESS accelerator collaboration
