Senior Engineering Team (SET)

SET Members:

  • Electrical Engineer (Control Systems, Infrastructure, RF)

  • Mechanical Engineer (Cryogenics, Vacuum)

  • Physicist (Accelerator, Diagnostics, Beam lines)

  • Industrial Engineer (Maintenance Management, Documentation)

  • Safety Specialist (“online” safety, procedures for present and future)

  • Two accompanying part time technicians

    Responsibilities:

  • Operation

  • Systems Commissioning and Acceptance

  • Maintenance

  • Engineering and Technical Office

  • Training


Operation

  • Most infrastructure systems were accepted and serve accelerator installation and commissioning purposes

  • SET members ware trained up to supervisor level to operate the infrastructure systems


Accelerator Systems Commissioning and Acceptance (1)

  • SET members are participating and assisting in accelerator installation, commissioning and acceptance tests

  • Effort is lead by the accelerator contractor personnel and is under their responsibility


Accelerator Systems Commissioning and Acceptance (2)

  • Emphasis is on thorough learning and understanding of all systems and components

  • SET members spend about 40% of their time on these tasks


Engineering and Technical Office

  • Engineering tasks and Technical Office responsibilities are entwined

  • Engineering

    • R&D of accelerator supplementary systems (Control, Diagnostics, infrastructure)

    • Writing maintenance and operating procedures

  • Technical Office

    • Documentation of engineering tasks

    • Updating of documentation and drawings

    • Archiving of engineering data

    • Maintenance schedule

    • Coordination among SARAF and external contractors and suppliers

    • Purchasing of spare parts and stock management


Maintenance

  • Maintenance procedures concern operational and mechanical systems conditions

  • Currently, maintenance is mainly performed on

    • The building

    • Infrastructure systems

    • Cryogenics

    • Part of the accelerator vacuum and RF

  • The maintenance works are divided into:

    • Breakdown Maintenance (BM)

    • Preventive Maintenance (PM)

    • Predictive Maintenance (PdM)


Breakdown Maintenance (BM)

  • Most of the systems are still in their warranty periods, so they are usually repaired by the system contractor

  • In urgent cases, breakdown maintenance is performed by SET members

  • The procedure for BM is

    • BM is requested in the commissioning logbook (if encountered during shifts) or in a PM form (if encountered during PM)

    • The BM Request is accepted and checked by the relevant SET member

    • A BM form is issued

    • BM is performed according to the procedures

    • A BM technical report is prepared

    • The BM technical report is checked and approved by the SET head

    • The data base of the Computerized Maintenance Management System (CMMS) is updated

    • The approved report is logged and stored in the BM archive


Preventive Maintenance (PM)

  • For accepted systems PM procedures have been written and scheduled by the technical office

  • The procedures are based on the system contractor requests and maintenance timetables (with small deviations)

  • PM is performed either by SET members, the system contractor or other external contractors

  • The procedure for PM is

    • A PM procedure form is issued by the technical office

    • PM is performed and reported on the form

    • The PM report is checked and approved by the SET head

    • The data base of the CMMS is updated

    • The approved report is logged and stored in the PM archive


Predictive Maintenance (PdM)

  • Predictive Maintenance (PdM) is an integral part of preventive maintenance

  • Measurements of systems parameters are performed routinely to observe patterns and predict equipment breakdowns or malfunctions

  • Typical measurements and operations include

    • Thermal imaging of electrical cabinets

    • Electric current measurements of motors and other equipment

    • Pressure and flow measurements of process cooling water systems

    • Gas and water analysis in relevant systems


Computerized Maintenance Management System (CMMS)

  • For the abovementioned tasks we developed a Computerized Maintenance Management System (CMMS), which enables SET members to schedule and structure maintenance tasks

  • The SARAF CMMS is a Microsoft Access based maintenance database management system which includes

    • Assets Management

    • Preventive Maintenance Scheduling and Management

    • Report Generation

Workload during commissioning


Conclusions

  • Development and assimilation of maintenance and engineering systems during accelerator installation and commissioning presents a big challenge for SARAF Senior Engineering Team.

  • Currently, the biggest effort is the accelerator installation and commissioning, so maintenance and engineering receive a smaller share of the workload

  • It is unequivocal that after the accelerator systems will be accepted, the maintenance load will grow accordingly. Therefore major SET tasks are:

    • Verified written procedures

    • A CMMS including all of the accepted systems

    • Appropriate training of SET members

    • Development of a maintenance culture
