The first measurements of energetic particle-driven ion cyclotron emission (ICE) in the Mega-Amp Spherical Tokamak Upgrade (MAST-U) have been obtained by adding a high sampling rate (250 MHz) capability to one coil of the existing OMAHA array, oriented to measure fluctuations in the toroidal magnetic field component. All these measurements were carried out in pulses with either on-axis neutral beam injection (NBI) only, or a combination of on-axis and off-axis NBI. Two types of energetic particle–driven ICE have been detected: a narrow-band emission with frequencies close to the on-axis deuterium ion cyclotron harmonics, fcD, exhibiting some frequency splitting and closely tracking fcD; and a broader-band emission that spans the frequency range from cyclotron harmonics at the magnetic axis to those at the outer plasma edge. The broader-band emission appears as a broadband signal when analyzed over a sufficiently long time window and consists of a set of transient sparks at closely spaced but distinct frequencies. This broadband type of ICE is reported from the edge in conventional tokamaks but covers a substantial part of the plasma in the spherical tokamak MAST-U.
