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

EVM Graph - Comments
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
EVM Graph - Comments
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)

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
