Max Magnetic Field for Pyrobreaker
|
Q.
((Lot 2 - FDU)
>From Technical Specification at § 4.1 we understand that only the mock-up will be installed in the FCCTF.
>From this and from § 11.1 we deduce that for the Pyrobreaker the max magnetic field will be less than 10 mT (i.e. not 100 mT).
Is our understanding correct?

A.
(Lotto 2) 1) Yes I confirm that only mock-up (prototype) will be installed in the FCCTF. Further the mock-up will not have the pyrobreaker.
2) In Section 11.1 The magnetic field in these areas, related to the DTT operation, will be less than 10 mT. Whereas for FCCTF area magnetic field will be in the range of 20 – 100 mT at about 4 m of distance from the cryostat and for type of coil. Finaly for pyrobreaker the magnetic field is less than 10 mT.
This means that in the building n. 184 (where 3 FDUs completed by pyrobreaker will be installed) the aspected value of magnetic field is 10mT whereas in the FCCTF (where mock-up will be installed) the aspcted value of magnetic field is much higher 20 – 100 mT. Thus noly for mock-up shall be put in place mitigation actions to reduce the effect of higher magnetic field.
