Transductor, Bdot and Magnetic Field Inside Reference Magnet Box Spectrums

X. Zhang, K. Triplett

Summary

• Using Gaussmeter, the peak field measured near the two GPMS buses on the wall is about 25Gauss.

• The peak file inside the reference magnet box for the proposed new transductor location is about 7 Guass (combined, likely due to the bus), which is satisfying the recommend external field limit 50 Gauss for precision measurement.

• The 720Hz signal are near the noise level of about 80dB lower than 15Hz, except for the Bdot signal monitor.
