Performance of a 20-in. photoelectric lens image intensifier tube
چکیده انگلیسی

We have evaluated a 20-in. photoelectric lens image intensifier tube (PLI) to be mounted on the spherical focal surface of the Ashra light collectors, where Ashra stands for All-sky Survey High Resolution Air-shower Detector, an unconventional optical collector complex that images air showers produced by very high energy cosmic-ray particles in a 42°-diameter field of view with a resolution of a few arcminutes. The PLI, the worlds largest image intensifier, has a very large effective photocathode area of 20-in. diameter and reduces an image size to less than 1-in. diameter using the electric lens effect. This enables us to use a solid-state imager to take focal surface images in the Ashra light collector. Thus, PLI is a key technology for the Ashra experiment to realize a much lower pixel cost in comparison with other experiments using photomultiplier arrays at the focal surface. In this paper we present the design and performance of the 20-in. PLI.


► We have evaluated a 20-in. photoelectric lens image intensifier tube (PLI).
► The PLI is the worlds largest image intensifier.
► The PLI is mounted on the focal surface of the Ashra light collector.
► Ashra stands for All-sky Survey High Resolution Air-shower Detector.
► The PLI is the key to realize all-sky survey with a few arcmin resolution in Ashra.
