Field Quality of MQ. Measured in SM18 Presented by: Stephane Sanfilippo AT-MTM-AS
What we measured so far. • 49 arc SSS tested at cold. • Field strength :48 MQ measured : • 7 MQ measured with the scanner (rotating coils). • 40 MQ measured with the SSW system. • Analysis performed on 21 MQ. • Field Quality (multipoles) :16 MQ’s magnets cold tested in the SSS. • 15 X-section 1+1 X-section 2
Warm/cold correlation status (MQ). (established at nominal current) sw/c~3 units (scanner) sw/c~5 units (SSW) Offset of~17 units between the two systems. scanner not properly calibrated ? MQ 120 (X section-2) out of the correlation. W/C correlation for strength not validated for the MQ. Standard measurements (shaft + SSW) have to be maintained for MQ ‘s in the SSS until validation.
Warm/cold correlation status (MQ). MQ 120 b6 b4 MQ 120 (X section-2) out of the correlation. +2.3 units of difference. Nominal : Offset of -0.34 units. sw/c~0.22 units Injection : Offset of -3.8 units. sw/c~0.33 units Offset of -0.3 units. sw/c~0.36 units
