Figure 4From: Development of a 3He magnetometer for a neutron electric dipole moment experimentDiscrete Fourier spectrum obtained from a 10 second long data sample from the lamp-pumped CsOPM. Peak of carrier frequency at 3513 Hz, sidebands from the 3He FID and 50 Hz sidebands are visible. 3He was polarized in situ and precession occured around the cosine-theta field direction. The output signal of the CsOPM was digitized at a sampling rate of 50 kHz with a resolution of 18 bits.Back to article page
