Abstract We propose 260 ks of INTEGRAL time to perform a ToO observation of a transient millisecond X-ray pulsar in outburst. The target can be either one of the five known transient accreting millisecond X-ray pulsars in the case of a new outburst or a newly observed object of this class. Since these sources are a new class of astronomical objects, INTEGRAL observations will give a fundamental contribution providing a sufficiently detailed spectrum at energies higher than 20 keV. In particular we will be able to study the energy spectrum of these sources, which is usually observed to be quite hard even in outburst, in a broad band energy range and with unprecedented high sensitivity above 20 keV, which will allow us to disentangle the contribution of soft, reflection and hard spectral components.The INTEGRAL observation will also allow to perform a timing analysis in an interesting and yet unexplored energy range.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
