“…The light entrance window on the ohmic side comprises an n þ ion implanted layer and an anti-reflective coating (ARC) surface. The layers are optimized to provide a sufficient depletion depth and to acquire all of the incident light [11]. An n-channel stop structure [12] is employed as a field shaper to suppress the leakage current from the edge.…”

The Cosmic Ray Energetics And Mass (CREAM) mission is planned for launch in 2015 to the International Space Station (ISS) to research high-energy cosmic rays. Its aim is to understand the acceleration and propagation mechanism of high-energy cosmic rays by measuring their compositions. The Top Counting Detector and Bottom Counting Detector (T/BCD) were built to discriminate electrons from protons by using the difference in cascade shapes between electromagnetic and hadronic showers. The T/BCD provides a redundant instrument trigger in flight as well as a low-energy calibration trigger for ground testing. Each detector consists of a plastic scintillator and two-dimensional silicon photodiode array with readout electronics. The TCD is located between the carbon target and the calorimeter, and the BCD is located below the calorimeter. In this paper, we present the design, assembly, and performance of the T/BCD.

“…The detector configuration makes possible to provide not only position of incoming light, but also depth of interaction in crystal scintillator. The DOl is given by measuring signal to noise ration between the first and second photo-strip sensors [1]. We measure the energy resolution of fabricated 1 cm Table 1.…”

We fabricate single-sided strip sensors that are sensitive to light. The strip sensors are AC-coupled, which has coupling capacitors and bias resistors. The sensors are fabricated on a high resistivity and double-sided polished n-type silicon wafer. The sensor is designed as the single-side strip sensor but its backside (n-side) is modified to be sensitive to incoming light. This photo-strip sensor is designed to measure positions of incoming gamma ray and alpha particle. The photo-strip detector consists of two photo-strip sensors and one crystal scintillator. The sensors sandwiching opposite faces of a scintillator are oriented orthogonally to each other to provide two-dimensional position information. When particles enter a crystal, the scintillator light of a crystal is emitted and penetrates into the photo-strip sensors. The lights are then converted to electron-hole pairs in the sensors. The detector configuration provides not only two-dimensional position information, but also the depth of interaction (001). The 001 is given by comparing signal-to-noise ratio between the first and second photo-strip sensors. The fabricated sensors are electrically tested by varying bias voltages. The pulse heights of the detector are measured by using Am-241 alpha, Na-22 and Cs-137 gamma ray sources. The position information is obtained with one photo-strip sensor and the LYSO crystal scintillator by using Am-241 alpha source. An experiment to obtain two-dimensional position information with two photo-strip sensors and a scintillator crystal is on going.
