Study of space charge compensated LEBT for ESS [PDF]

, 2005
To fulfil the requirements of ESS on beam transmission and emittance growth a detailed knowledge of the physics of beam formation as well as the interaction of the H- with the residual gas is substantial.

Characterization of a cryogenic beam source for atoms and molecules

, 2013
We present a combined experimental and theoretical study of beam formation from a cryogenic buffer gas cell. Atoms and molecules are loaded into the cell by laser ablation of a target, and are cooled and swept out of the cell by a flow of cold helium. We

Gas extraction from insulating liquids - Part II

Transformers Magazine, 2022
As widely described in the first part of the column, all types of partition coefficients between liquid and gas phase are highly dependent on the physical and chemical properties of materials and process involved. In this second part, the large variation of extraction methodology will be described.

The gas chain: influence of its specificities on the liberalisation process. NBB Working Papers. No. 122, 16 November 2007 [PDF]

, 2007
Like other network industries, the European gas supply industry has been liberalised, along the lines of what has been done in the United Kingdom and the United States, by opening up to competition the upstream and downstream segments of essential ...
