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.
