Abstract

The power density distribution in multipole-wiggler radiation was measured using a photocalorimetric device. The measured density was lower than the value calculated using Kim's formula for undulator radiation by about 20% at the peak density. It was ascertained that Kim's formula gives a power density of multipole-wiggler radiation accurate enough for power estimation, and that the photocalorimetry is a useful mean for measuring high-power X-radiation.
