    "abstract": "The parametric instability of upper hybrid wave decay into back scattered\nupper hybrid wave and lower hybrid wave is considered for conditions of\ninhomogeneous plasma of spherical tokamaks. The possibility of absolute\ninstability is demonstrated and the corresponding threshold is determined. It\nis shown that the threshold power increases with pump frequency and electron\ntemperature. Threshold power is estimated for typical parameters of experiment\nin MAST tokamak. It is shown that in this case parametrical reflection arises,\nif probing power exceeds 90W/cm^2, which gives 30 kW for a beam of 10 cm\nradius.",
