bull Shimming nominal (shimming such that in the press the mid-plane of the cured coil is like in the magnet 012 mm above center axis)bull This is different compared to FERMILAB where oversized shimming

is used to compact the coil mid-plane beyond its nominal position in order to obtain a smaller coil size before entering into reaction

bull With a load of 08 MN the mold is nearly closed (lt 01mm)bull Then a load of 2 MN is used for IL and 42 MN for the OL

(complete pole)bull The stress in the coils may not exceed 37 MPa at that stage

D SmekensJ Mazet

Reaction treatmentbull Cavity of the reaction fixture is radially bigger than the curing

mold by 01 mm and of similar dimension at coil mid-planebull Thus if the curing press can be closed before reaching 37

MPa the coil cannot be subjected to higher stress when closing the fixture However the dry fiber glass and the tight tolerances induce large friction also a possible dimensional problem with the sealing foils could have generated interference between the sealing foil and the baseplate preventing correct closure of the fixture

bull The tightening torque to close the fixture was of the order of 300 Nm (FNAL applies 110 Nm to 160 Nm)

bull Not clear no coil contraction after reaction actually less that 1 mm when 45 mm were expected

Reaction treatmentbull Cavity of the reaction fixture is radially bigger than the curing

mold by 01 mm and of similar dimension at coil mid-planebull Thus if the curing press can be closed before reaching 37

MPa the coil cannot be subjected to higher stress when closing the fixture However the dry fiber glass and the tight tolerances induce large friction also a possible dimensional problem with the sealing foils could have generated interference between the sealing foil and the baseplate preventing correct closure of the fixture

bull The tightening torque to close the fixture was of the order of 300 Nm (FNAL applies 110 Nm to 160 Nm)

bull Not clear no coil contraction after reaction actually less that 1 mm when 45 mm were expected

bull Shimming nominal (shimming such that in the press the mid-plane of the cured coil is like in the magnet 012 mm above center axis)bull This is different compared to FERMILAB where oversized shimming

is used to compact the coil mid-plane beyond its nominal position in order to obtain a smaller coil size before entering into reaction

bull With a load of 08 MN the mold is nearly closed (lt 01mm)bull Then a load of 2 MN is used for IL and 42 MN for the OL

(complete pole)bull The stress in the coils may not exceed 37 MPa at that stage

D SmekensJ Mazet

Click here to add footer 7

Reaction treatmentbull Cavity of the reaction fixture is radially bigger than the curing

mold by 01 mm and of similar dimension at coil mid-planebull Thus if the curing press can be closed before reaching 37

MPa the coil cannot be subjected to higher stress when closing the fixture However the dry fiber glass and the tight tolerances induce large friction also a possible dimensional problem with the sealing foils could have generated interference between the sealing foil and the baseplate preventing correct closure of the fixture

bull The tightening torque to close the fixture was of the order of 300 Nm (FNAL applies 110 Nm to 160 Nm)

bull Not clear no coil contraction after reaction actually less that 1 mm when 45 mm were expected

Reaction treatmentbull Cavity of the reaction fixture is radially bigger than the curing

mold by 01 mm and of similar dimension at coil mid-planebull Thus if the curing press can be closed before reaching 37

MPa the coil cannot be subjected to higher stress when closing the fixture However the dry fiber glass and the tight tolerances induce large friction also a possible dimensional problem with the sealing foils could have generated interference between the sealing foil and the baseplate preventing correct closure of the fixture

bull The tightening torque to close the fixture was of the order of 300 Nm (FNAL applies 110 Nm to 160 Nm)

bull Not clear no coil contraction after reaction actually less that 1 mm when 45 mm were expected
