MYRRHA

The MYRRHA project introduced by SCK-CEN ( Belgium) proposes the installation, on its site of Mol, of a system ADS (Accelerator Driven System) intended for the studies and  the demonstration of the transmutation of the nuclear waste of high activity. At first, within the framework of the European projects EURATOM (FP7 and H2020) and for 3 years with direct contracts with the SCK, ACS is involved in the studies relative to the accelerator of protons of high intensity and, in particular, in the field of the superconductivity and associated cryogenic systems.

Activities 2017/2018

Technical support on general aspects of the project: cost estimate of investment and functioning.

Study of industrialization for the elements of the LINAC connected to the cryogenic systems and the cavities.

Thesis on the development of the artificial intelligence dedicated to particle accelerators.

Modelling of cavities Spoke for the optimization of the control system.

Studies of a valve box for the prototype of the cryomodule SPOKE – Specification and design.

FREIA

FREIA is an infrastructure of test situated in Uppsala, Sweden. FREIA is equipped with sources RF as well as dedicated diagnostic equipment, helium liquefier, cryostats 2 K, pumping systems, test areas in a hall of experiment of 1000 m ².

The horizontal test cryostat – HNOSS- is used for the test of supraconducting cavities for the accelerator ESS (European Spallation Source) in Lund.
From 2012, ACS worked on the design studies of the horizontal test cryostat HNOSS. Having assured its production monitoring, the cryostat was installed at the end of 2014.
In 2018, a new vertical cryostat – GERSIMI – was installed in Uppsala with the cooperation of the ACS team, in particular responsible for commissioning tests : installation, cooldown, command & control tests

FRIB

FRIB is an installation dedicated for the production and the use of rare isotope beams , situated in the university of Michigan State.

 

ACS developed for MSU the cryogenic and mechanical design for typical FRIB FSQ5 Q-poles (Dewar Box)

This study was realized at the end of 2017 and included the details drawings as well as the calculation notes.

ITER-F4E-OFC-433

Within the Framework Contract (reference F4E-OFC-433) “Integration Design of Diagnostics into the ITER Ports”, different management and engineering services are required and will be performed by IDOM as main contractor. The work to be developed by ACS, as subcontractor, concerned the “Electromagnetic (EM) Studies for the
Integration Design of Diagnostics into the ITER Ports”.

During the first contract covering the period from October 2014 to March 2016, ACS developed EM analysis activities to assess the methodology, initially proposed by F4E, to analyse the modelling feasibility and to perform different benchmarking tasks.

During the second contract covering the period from April 2016 to end March 2017. ACS achieved detailed EM analysis for 5 Diagnostic Ports in order to reach an intermediate maturity level called Preparatory Design.
The last project phase is part of the F4E specific contract SC04 . It consists to continue the calculation on  the 5 Diagnostic Ports until reaching the Preliminary Design Review (PDR).

European program - topic NFRP-09-2015

European program from October 01st, 2016 to 31 March 2019-topic NFRP-09-2015

MYRTE project is coordinated by SCK.CEN. The consortium includes 27 European organizations including research institutes, universities and industries.

Having participated in the europeans projects MAX and MARISA, ACS contributes to the project MYRTE on 3 particular subjects:

  • Test of cavities SPOKE in the institute of physical nuclear of Orsay: preparation of cavities, cryogenic tests, result analysis.
  • Study on a cost estimation for the construction of the LINAC Myrrha.
  • Contribution to the definition and the preliminary study of the cryogenic control systems.

SARAF

The market fits within the framework of the agreement of collaboration signed on April 25th, 2015 between CEA (ATOMIC ENERGY COMMISSION) and Soreq Nuclear Research Center in Tel Aviv (Israel) for the realization of the phase 2 of the accelerator project SARAF.

Soreq Nuclear Research Center is an entity of the IAEC (Israeli Atomic Energy Committee(Commission)), and is situated in Yavne (Israel).

According to the terms of this agreement, CEA (ATOMIC ENERGY COMMISSION) was responsible of the design, the realization and the assembly of this accelerator.
ACS and AITR won in December 2017 all design studies of the ECTS cryostat for the accelerator SARAF

Vertical Cryostat

July 2017

The contract consisted of the realization of a vertical test cryostat as well as the final assembly of all the components.
ACS was in charge of developing the assembly files and instrumentation for the vertical cryostat for  SPOKE cavity test as well as the production monitoring.

European Spallation Source

ESS (European Spallation Source) is under construction in the city of Lund, Sweden. ESS will have a powerful accelerator of protons. In the beginning of 2022, the first instruments will be put into service.

In May 2018, ACS, in association with AITR, won a contract for the manufacturing follow-up and technical consulting for the production of 13 valves boxes for the cryogenic SPOKE section of the LINAC.
