Abstract: A polarization separating element such as a beam splitter receives a first light of a first polarization plane. The polarization separating element derives out of the first light a second light of a second polarization plane set perpendicular to the first polarization plane. A photoelectric element converts the second light into an electric signal. The intensity of the second light is in this manner detected.

The extinction ratio of the second light accurately reflects the extinction ratio of the first light. The detection of the intensity of the second light at the photoelectric element enables an accurate detection of the intensity of the first light.

In an embodiment, two polishers that absorb carbon dioxide and silicon dioxide, but which have a greater affinity for carbon dioxide, are placed in series along a conduit containing the liquid for use in an immersion lithographic apparatus. The upstream polisher absorbs carbon dioxide and silicon dioxide until it is saturated, at which point it desorbs the silicon dioxide in preference for the carbon dioxide. Silicon dioxide continues down the conduit and is absorbed by the downstream polisher. Once the upstream polisher is saturated with carbon dioxide, carbon dioxide present in the liquid flows downstream where it is absorbed by the downstream polisher. A sensor between the polishers senses the presence of carbon dioxide and initiates a request for the one or more of polishers to be cleaned or replaced.

Abstract: A radiation attenuation corridor couples a radiation therapy room and a control room. The radiation attenuation corridor is made of a material that substantially absorbs ionizing radiation and substantially blocks the transmission of the ionizing radiation. Specific wall portions at the entrance of the corridor are covered with borated polyethylene (BPE).

The corridor thus leads out of the room and angles laterally across the wall of the therapy room, before angling again and opening to a safe room. The added angles in the radiation corridor increase the distance of radiation travel, and make the path more indirect, thereby increasing the contact of the radiation emissions with the radiation shielding and further attenuating the radiation.
