New results in optical fiber Cherenkov calorimetry

Quartz fiber calorimetry is a sampling calorimetry technique based on the detection of Cherenkov light generated in quartz optical fibers. Optical fibers transport only selected modes of light which results in very narrow visible showers. In addition, this technique is characterized by radiation resistance measured in gigarads and nanosecond pulse duration. The results of recent beam tests are presented, illustrating behavior of electromagnetic calorimeters based on this technique as a function of their absorber type, density and distribution of fibers and fiber types.
