Introduction to the temporary safety system for Cyclotron test Simplified access system: only a reduced area is accessible

nobody is allowed to be at -1 level during test high shielding doors installed Radiological survey system: n-g monitors already available at LNL will be used temporary data acquisition system is under developing Cyclotron interlocks: BEST safety system cyclotron interlocks used (SIL3 contactors)Beam line interlocks: vacuum, overcurrent, beam collimators Beam dump interlocks: Beam Dump hot spot temperature, cooling water pressure, mass flow rateTemp. Safety control system: Standard PLC-based system

SPES handling system

Horizontal handling system

A two cartesian axis system mounted onto an AGV unit allows the handling and transfer of the TIS.

Test bench handling

A test-bench Front End coupling table

allows to

verify the TIS connection /disconnection from proton and RIB beam lines.

A tool to disconnect the puller was developed too.

Coupling table

Puller removing system

Once per year it is expected to change the puller, an highly activated component.

The handling system is equipped with a tool able to extract the puller and to store it in a shielded box.

ConclusionsThe SPES cyclotron is under installation and will be soon ready for testA temporary safety system is under development to operate in a safe way

In the following talks we present the status of the systemWith this meeting we ask for your opinion/suggestions on the work we are doing.Development of a temporary safety system:How do you assess our approach? Do we have the appropriate level of care?Are we considering all the critical elements?Is the work sufficiently well coordinated?

Are the human

resources

adequate
