The Karlsruhe — CERN superconducting rf separator

Status of "OKA" experiment

“…Nominal parameters of the deflectors [5] and calculated parameters of the beam [6] are shown in the Tables 1 and 2 correspondingly. There were, however, some problems with the deflectors. First of all, it turned out that one of the deflectors (RF2) was damaged at CERN during preparation for the shipment to Russia.…”

An rf separated kaon beam from the Main Injector: Superconducting aspects

“…It was very early recognized, however, that a superconducting separator operating with a long pulse would have a more general usefulness [10], and about 1967 a collaboration began for design and construction of such a device [16,17]. The completed system began operation late in 1977 [14,25]. Some of the parameters of the superconducting waveguides are listed in Table 3.4 below.…”

“…The operating frequency is locked to one of the resonators. Each resonator has Kapton windows in the beam line to protect the cavities from contamination [14,22,24,25]. The deflection is in the vertical plane.…”

“…For a review see [14]. Much of this is not of current interest, but there are several themes that are important here.…”

“…However, if the 10 subsections had been operated independently at their respective gradient limits, a total of 10.45 MV [14] would have been produced. [11] This is an application of the so-called area argument.…”
