Lowering of the cryogenic transfer line segments to USC55.

The pictures show the transfer of the helium transfer line segments to the USC55 cavern. The transport of the just under 12m long segments has been achieved by the means of a tilting table

Installation of the intermediate cryostat.

Manufacturing of the test cryostat. The test cryostat is used to simulate heat loads of the CMS magnet for the acceptance tests of the refrigeration system.

The picture shows the testing configuration of the helium refrigeration system with the intermediate cryostat (6000l) and the temporary test cryostat

Arrival of the cold box for the cryogenic refrigeration plant and installation in building SHL5.

The pictures show the arrival of the cold box and the installation of both the cold box and the valve panel in building SHL5. The installation was achieved by lowering the components through an opening in the roof which had been specially forseen for this operation

Introduction to cryogenic engineering

Cryogenic engineering is one of the key technologies at CERN. It is widely used in research and has many applications in industry and last but not least in medicine. In research cryogenic engineering and its applications are omnipresent from the smallest laboratories to fusion reactors, hughe detectors and accelerators. With the termination of the LHC, CERN will in fact become the world's largest cryogenic installation. This series of talks intends to introduce the non-cryogenist to the basic principles and challenges of cryogenic engineering and its applications. The course will also provide a basis for practical application as well as for further learning

TREC: Full Traceability of Radioactive Equipment and Related Processes

TREC is since 2009 CERN’s official application used for traceability of radioactive equipment. Being fully based on the organisation’s Asset and Maintenance Management system, EAM, the radiation protection aspects for physical equipment are now managed as a completely integral part of the asset lifecycle. This paper gives an overview of the main capabilities of TREC and its growing number of modules that today not only support radiation measurements of equipment but also radioactive waste management, water release management and traceability of RP laboratory processes. The paper explains also how TREC has evolved over time from its original main focus on traceability aspects to now also orchestrating several different workflows

Maintenance Contract Management and Cost Reporting with EAM

CERN has outsourced numerous installation and maintenance activities in many different technical domains to external companies. One key responsibility and challenge of each CERN responsible of these service contracts is to perform the cost controlling for the outsourced activities. This paper introduces the functionalities that CERN’s Enterprise Asset Management (EAM) system provides to assist the CERN contract managers in their cost controlling tasks. It starts by presenting the methods for tracing different types of expenditures during the execution of activities, be it in the framework of resource provision contracts, be it in the framework of fixed cost per service contracts or any combinations thereof. It then presents the configurations and adaptations of the standard cost aggregation functionalities in EAM to the needs of the users at CERN. This is followed by the explanation how contractual conditions can be reflected in EAM in the form of contract records and how the expenditure collected during the work execution can be extracted in the form of flexible cost reports or in the form of traceable periodic cost statements allowing comparison with the contractors’ invoices
