Abstract
The design of the phototube power supply for the HERA-B Electromagnetic Calorimeter is presented. A choice of the solution on the basis of the Cockcroft–Walton voltage multiplier is validated. Schematics developed are discussed. A special section describes the behaviour of the crucial components under irradiation since radiation tolerance becomes one of the most important items in the severe HERA-B radiation environment. Finally, performance achieved is presented.File in questo prodotto:
