Vacuum ultraviolet emission of a permanent magnet undulator on the ACO storage ring in Orsay

2014 We present VUV emission spectra taken on the ACO storage ring from the permanent magnet undulator NOEL (1), currently dedicated to free electron laser experiments, along with an overview at the properties of undulator radiation. The analysis of the spectra includes corrections for the emittance of the electron beam and a small mismatch between the direction of the measurement and the undul...

Experimental Study on Heat Transfer Performance of Vacuum Tube Heat Collector with Thermal Storage

This experimental study is intended to explore the heat performance of a novel vacuum tube heat collector with thermal storage. In order to enhance the heat transfer performance, we add radial metal fins to the U-tube which is used as the heat transfer channel of water. Meanwhile, in order to increase the thermal capacity of the heat collector, the heat collector model is designed to be larger ...

Development of Ultrahigh-sensitivity HARP Pickup Tube and Its Applications

In 1985, the author found for the first time that an experimental pickup tube with an amorphous selenium photoconductive target exhibits high sensitivity with excellent picture quality because of a continuous and stable avalanche multiplication phenomenon. We named the pickup tube with an amorphous photoconductive target operating in the avalanche-mode “HARP”: High-gain Avalanche Rushing amorph...
