A semiconductor detector cryostat [PDF]

Nuclear Instruments and Methods, 1967
Abstract This report describes in detail the mechanical design of a multipurpose cryostat system for nonencapsulated Ge(Li) and Si(Li) semiconductor radiation detectors. We have attempted to provide a standardized system that will accept many styles and sizes of detectors, and that lends itself to many kinds of experiments.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

Advanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

On Determining Dead Layer and Detector Thicknesses for a Position-Sensitive Silicon Detector [PDF]

, 2018
In this work, two particular properties of the position-sensitive, thick silicon detectors (known as the "E" detectors) in the High Resolution Array (HiRA) are investigated: the thickness of the dead layer on the front of the detector, and the overall ...
