Second step of the upgrading of the Strasbourg MP (16–18 MV)

Abstract Following a first upgrade, the Strasbourg MP Tandem operated 16 MV. A second stage was recently completed and in July 1982 the MP ran at 18 MV with beam for the first time. This second stage consisted of two main parts, first the installation of a new number 1 accelerator tube of 96″ length and second the installation of a Vivitron portico which modifiers radially the distribution of the stored energy and the radial field.
