Progress on the superconducting RF-particle separator for CERN

The status of the deflectors for the superconducting rf separator is given. The design values for the Q-factor (Qo = 5.10
⁸
) and the deflection field (E
o
= 2 MV/m) have been reached in two combined 60 cm sections. During a 430 h run at design field no deterioration of Q
o
and E
o
was observed. In a first measurement with a full deflector assembled from 5 sections (10
⁴
cells) Q
o
= 9.10
⁸
and E
o
= 1.2 MV/m corresponding to a peak magnetic field of 19 mT have been reached.
