The LANSCE linear accelerator consists of a 201.25-MHz, drift-tube linac and an 805-MHz, side-coupled-cavity linac (SCL). Beam losses in the high-energy beamlines of the 800-MeV facility were measured versus variation of the amplitudes and phases of the 805-MHz, SCL, RF cavities. A recent study* confirms that to achieve low losses, the stability of the amplitudes and phases should be kept within 0.1% and 0.1o, respectively. This agrees with a previous study of beam losses in the 201.25-MHz linac. Details of the measurements and results are presented.
