Description

The cyclotron JULIC at Forschungszentrum Jülich (FZJ), has been operating for over 56 years. It is a remarkable example of innovation, long-lasting technology and reliability. With its high performance and versatility it was an essential part of the FZJ research program in the field of nuclear physics, irradiation experiments for medical, technical and space application and radiation effects in materials and electronics. During JULICs long life many changes and improvements widened its working spectrum. With the superconducting ECR ion source ISIS, JULIC has accelerated highly charged heavy ions up to Ne, enabling nuclear physics research with light towards heavy ions. Since 1993 and with its colliding beams source CBS, JULIC has delivered unpolarized and polarized proton and deuteron beams to the Cooler Synchrotron COSY and its hadron physics research program and for the JULIC-Neutron Platform with pulsed beams of cold to fast neutrons. Even with operation of proton and deuteron beams mainly, JULIC hasn't lost its ability to run with other species as shown with acceleration of He-3-beams lastly. The technical improvements made to the JULIC systems over the years, like the adaptation of the diagnostic and timing system to meet different experimental needs or transition to an oil-free vacuum system are just a few of the many, led to its high reliability and operational efficiency. Thus all is a testimonial to the ingenuity and dedication of the FZJ staff who made it possible.
