CEA-ESSI meeting July 2019 Mats Lindroos on behalf of the ACCSYS sub-project www.europeanspallationsource.se July 3, 2019
Highlights • First 15 CDS – EL sections have been installed in the tunnel with 3 more just being moved done to the tunnel. First LWU has already arrived at ESS! • 6 LWUs completed at STFC Daresbury and now at ESS. Rest to follow in 2019. • Waveguide installation in Elliptical linac stubs keeping ahead of CDS installation! • RFQ stub conduits installed and wave guides under installation • The first series ESS modulator for the NC linac has arrived at ESS and testing is just starting at test stand 3. The 2nd series modulator FAT done and 3rd under way. • MEBT from ESS Bilbao has arrived at ESS and installation is done • AD-ICS program forum chaired by new testing and commissioning manager started. Sets priorities 2 months ahead for AD and ICS. • The ion source and LEBT commissioning is under way, required beam performance has been demonstrated • The spoke cryomodule prototype is undergoing tests at the FREIA test stand in Uppsala. • Measures to improve shielding for racks and cables have been proposed by a task force and now are now being implemented • The new infrastructure sub-project assures that infrastructure and components are in place for testing, commissioning and operation (see Peo’s talk)

Delays since last TB • RFQ: Further delays for the RFQ. We have now done the MEBT installation (which de-blocks the DTL installation this autumn) and we will do the RFQ installation once the MEBT is fully installed (with some parts removed for RFQ bead-pulling). • DTL: issues with the copper plating quality of one module for DTL1. Being redone. Parts starting to arrive in July for assemble in ESS DTL workshop. • SPOKE CMs: First CM to Uppsala delayed with 4 months. Testing in Uppsala is announced to take more time than planned. • CDS-SPOKE: Delay in manufacturing and installation schedule announced, work on mitigation for minimal impact at ESS has started • SPOKE RF AMPLIFIER: Delay in placing contract due to procurement issues and a failed CDR. Now first amplifier is being assembled and Elettra is closely following the concerned industries at all different sites with staff present to assure a timely completion of the project
Critical IK delays for accelerator • Report requested by Mark Anthony, Project Director on the five most critical In-Kind deliverables which either are on the critical path of is very close to the critical path: • The five issues are: RFQ (CEA), Spoke CMs (IPNO), Spoke CDS (IPNO), DTL (INFN) and Spoke RF amplifiers (Elettra/INFN): • RFQ from CEA/IRFU: No further delays compared to the present schedule agreed (after decision to go ahead with MEBT installation before RFQ installation). The original delay since the May 2018 re-baseline is very large. • Follow on effects: No direct follow on effects as we already installed the MEBT. An additional 2 months delay would affect start date for NC linac conditioning and commissioning. • Risks: We have 3 sections completed, 1 section under a second re-brazing to repair leaks and one section under manufacturing. Further issues with leaks after brazing on section 4 and 5 and possible additional machining mistakes at the factory could cause further delays. • Possible mitigation: We already mitigated with a change in the installation order which will enable us to proceed with the MEBT integration and DTL installation independently of the RFQ. We will also prepare all RF and infrastructure so that we can proceed with testing, conditioning and commissioning without delay after installation. • Key actions: 1) Mats and Håkan should continue bi-weekly phone meetings with CEA/IRFU ESS project lead and 2) Mats to assure high level representation at ESS-CEA/IRFU governance meetings.

Other Issues • It is becoming urgent to agree on local safety rules adopted to installation, testing and commissioning activities for the ESS buildings. • Temperature of temporary cooling water doesn’t meet specification (is too cold) and cleanliness. This is an irritation at TS2 but will likely prevent linac operation. • No changes can be done to the NC linac cable database any longer as design and orders are going ahead. Dead-line will now be set for the SC linac cable database (see Peo’s talk)

EAC • Table showing baseline followed by list of EAC items with estimated cost and total EAC
Other open points to discuss • RFQ skid, pipes must be replaced as the welds are poor. All other equipment will be kept. • Who pays? • Mounting of power couples at ESS • Training of ESS staff, when? Better to do the training in Lund so that all ESS staff can participate. • Can we agree on a strategy which minimizes risk for transport of CMs in Lund from test stand to tunnel? • With our without power couplers mounted? Who does what?
Summary • We see intense installation, testing and commissioning activities at site today • We have 2 very busy years ahead of us! • Every day matters to keep the schedule. I’m really grateful for the flexibility and commitment that all are showing to keep the sub-project moving • For the licensing and safety readiness reviews, only “100%” is good enough. Please give MamadEshraqi all the support he needs for licensing documentation and Wolfgang and Ciprian the support they need for the safety readiness reviews.
