Title Superconducting Cavity Production and Preparation at ACCEL Instruments GmbH
Type Poster cavity design / fabrication / treatment
Abstract The series production of 35 medium beta and 74 high beta cavities for the Spallation Neutron Source Linac allowed us to improve our cavity manufacturing and processing facilities. We are now able to produce one SNS cavity per week including chemical treatment and field flatness tuning. The SNS project occupies our two electron beam welding machines to only about 70 % in a one shift operation ensuring completion of the cavity production within the contractual foreseen three years period (140 weeks). In addition two TESLA type cavities for BESSY were produced within 6 months after provision of niobium. The preparation including tuning to field flatness, closed loop chemistry, high pressure rinsing and clean room assembly for vertical and horizontal tests is within our scope and is foreseen for the end of this year. A new high pressure rinsing system was developed and is currently built with the goal to achieve gradients in the 20 MV/m regime. A superconducting CH-mode cavity for acceleration of ions for Universitaet Frankfurt and two prototype half wave resonators (one for Forschungszentrum Juelich, one for SOREQ) for proton/deuteron acceleration are under production. Also those three cavities will receive chemical treatment, high pressure rinsing and clean room assembly with vertical test equipment at our facilities.
