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.

Cost variance mainly due to late invoices

17. EVM Graph - Comments Schedule variance = Earned Value – Planned Value
Behind Schedule
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

18. EVM Graph - Comments Cost Variance = Earned Value – Actual Value
Under Budget
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)

22. 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

23. 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)

24. 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

25. 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

26. 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
