Abstract

PURPOSE:To enable an SOR (orbital radiation) light absorber to be installed even in front of a SOR light takeoff port by providing a slit, through which SOR light can pass on a limited basis, in the absorber. CONSTITUTION:In a SOR (orbital radiation) light absorber 4, a slit is provided through which SOR light available in use to enter a SOR light takeoff port 1 can pass. That allows installation right in front of the port 1. The vicinity of the vacuum duct fitted portion of the port 1 can thus be protected from SOR light irradiation. Also, a SOR light irradiation area 5 can be limited in the vicinity, and degassing due to the SOR light irradiation to the vacuum duct 2 can therefore be concentrated on a local area. It is also possible to make vacuum exhaust efficient by arranging a vacuum pump in the vicinity of the absorber 4.
