Abstract (en)

[origin: WO9914615A1] Apparatus for transmitting an RF magnetic field pulse for use in an NMR or NQR experiment. The apparatus comprising a transmit antenna (10) for transmitting the RF magnetic field pulse and a switching element (12) such as a TRIAC which can be selectively switched on to couple a damping circuit to the transmit antenna. The damping circuit damps the transmit antenna by carrying a damping current. The switching element (12) is responsive to the damping current so as to switch off when the transmit antenna (10) has been damped to an acceptable level.
