• The scope contingency for the accelerator project consists of the RF sources and installation costs (after 2019) for the high beta-part of the linac

• The fully equipped cryomdoule for the high-beta linac are IK contributions and are not part of the scope contingency. The infrastructures needed for the construction of these are only available during ESS construction.

EVM Graph

Cost variance mainly due to late

invoices

FEB 2015

EVM Graph - Comments

Schedule variance = Earned Value – Planned Value

The schedule variance (-2.8 Million Euro) is mainly due to:

• -1.5 M€ New Vacuum plan not still in place in P6 (WP12)• -1.3 M€ Delay of ACCP contract signature ~1 week due to continued

contractual fine tuning (Cryo WP11) This has no impact on the final delivery date or on the beam delivery milestone

Behind Schedule

EVM Graph - Comments

Cost Variance = Earned Value – Actual Value

The cost variance (+0.7 Million Euro) is mainly due to:

• +0.7 M€ Effect of re-plan in January of the whole Beam Instr. WP (BI WP07)• +0.1 M€ Delay in payment to CNRS (Spoke WP04)• +0.3 M€ Effect of re-plan (NC linac WP03)• +0.5 M€ Delay in payment to CEA (Elliptical WP05)

• -0.5 M€ Effect of some re-plan on-going (RF WP08)• -0.3 M€ Uppsala University Invoice Q4 2014, coming in 2015 (Test stand

WP10)• -0.1 M€ Some discrepancies due to invoices for on-going 2014 contract

booked on the old PCC i.e. WP8 at the place of WP17 (Power Converters WP created on Sept 2014)

• Some other little fluctuations in all the WPs (mainly to salaries)

Critical Path - Accelerator

Accelerator Risks

– ACCSYS is currently tracking 182 risks including many detailed technical ones

– Most of these risks have treatment plans (the remaining ones are being developed)

– The nature of these risks is that most exist throughout the length of the project

– The Exonaut Risk software and database works well– Our ability to accurately estimate the costs of the risks is

limited

22

Accelerator Risks

• The likelihood of a few risks has been reduced since the 2013 Review due to experience to date. These include:– Lack of appropriate design and Product Data Management (PDM) tools’.

• This previously high-ranking risk has been re-assessed. Probability of this occurrence reduced significantly due to visit by D. Ferguson and due to resulting Lab-wide review of tools by a committee which made recommendations on improvements. This may be reassessed once the lab working group finishes implementing the recommendations (Q2 2015)

– ‘Political and financial considerations overrule technical considerations for IKC assignments.’

• Reduced probability of occurrence due to positive experiences of the last 12 months.

• An example of a retired risk is: ‘Decisions not made in time’– Risk retired due to ongoing experience with ACCSYS decision process. Mechanisms

exist for decisions being made in a timely manner • The fixed price for the ACCP (coming in under budget) helps reduce the cost risk to the

project)23

Accelerator Top Risks

• The top 5 risks for ACCSYS are:– Unidentified design faults cause failure during production– Suppliers do not meet scope and schedule requirements– In-kind contributors do not meet scope & schedule requirements– Inability to deal with on-site adjustments to components– Electrical machinery not powered down during maintenance (safety risk)

– Treatment plans (including design reviews, close communication with IKCs and suppliers, development of onsite installation and adjustment capabilities) are underway. The last risk will be dealt with via a site wide lockout/tagout procedure.

– In reality, the biggest single risk for success (this risk is held at the ESS level) remains retention of staff – Hiring has generally gone quite well, the real challenge is to avoid burn out

24

Next Six Months

• Hardware testing facility in Lund operational• Technical verification program full launched

• Audits and Reviews

• Integration and coordination of accelerator project• Review of all Level 4 requirements• Finalize IK contracts• Continue recruitment of staff to AD• Continue project work according to plan

25

Accelerator Summary

• The accelerator project is in a phase of intense prototyping and reviewing and will soon see most major systems in construction• Large part of prototyping and design done by in-kind partners• Essential to get in-kind contracts agreed and signed in 2015 to permit construction of all systems

to start in earnest• Work on (parts of the) RF design, modulators, beam instrumentation and cryogenic design done

in Lund

• Coordination, integration and verification represent a major part of the work done today by the accelerator division at ESS in Lund

• The accelerator division is recruiting according to plan and will be 2018 have 110 staff with some 40 being technicians

• The project schedule has many close critical paths which makes it sensitive to delays, even in activities which not necessarily are being seen as critical

• A testing facility which presently is the home of he reduced scal modulator prototype exists and will be further extended in the coming years

• The goal is to build and train the accelerator division so that it can assume full responsibility for operation and maintenance of the accelerator systems in 2019
