Rapid longitudinal relaxation measurement of hyperpolarized 129Xe by a highly sensitive atomic magnetometer

Abstract: A fast and accurate determination of longitudinal relaxation time is put forward for hyperpolarized 129Xe. The theoretical framework for the method is developed. Measurement of the longitudinal relaxation time is by the determination of a close-loop response of 129Xe magnetization to the external magnetic fields and is implemented with a highly sensitive Rb magnetometer. The indirect measurement dramatically reduces the time consuming than the conventional inversion-recovery method and is more suitable for the… Show more

“…We use a pump-probe scheme in our experiment. The pump-probe scheme has significant advantages and widespread applications in atomic magnetometers [3,5,[17][18][19], for example, the most sensitive spin-exchangerelaxation-free (SERF) atomic magnetometers [3], and the atomic gyroscope [1,20] applying the pumping beam to polarize the nuclear spin and the probe beam to detect the polarization. In addition, the pump beam and the probe beam characteristics (power, detuning, etc) can be separately optimized.…”

“…15,16 The longitudinal relaxation time can be obtained by an application of π and π/2 pulses. 17,18 Moreover, Linlin Chen et al determined the polarization of 129 Xe by using the π/2 pulse. 19 These studies indicate that the accurate measurement of π/2 pulse is significant.…”
