The cyclotron JULIC is used as injector for the COSY storage ring since almost 30 years. Beams of polarized and unpolarised H⁻ and D- ions are routinely accelerated using cyclotron HF system up to 45 and 55 MeV, respectively. Meanwhile, low energy beams from JULIC become more frequently used by the experimentalists, especially at the new low energy beam line, which connects cyclotron with the large Big Karl experimental hall. To meet the requirements of the cyclotron users a diagnostic system upgrade program has been started at the JULIC cyclotron. All destructive beam diagnostic systems (Faraday Cups) have been equipped with a new produced by CAEN TetrAMM based beam diagnostic systems. All TetrAMM devices are implemented into the common COSY Control System with EPICS readout and archiving environment. The cyclotron NMR field control system has been upgraded using the newest sensor from Metrolab (PT2026), which allows operation in complete field range of the JULIC cyclotron, without changing the sensor. A new Lock In-Amplifier based Data Acquisition System has been used for nondestructive beam intensity and position diagnostic at the Big Karl beam line. First tests have demonstrated possibility to measure current and position of the 10 nA DC beam using this technique. Since relatively long time cyclotron users were occasionally disturbed by unwanted 33 Hz noise at the output of the cyclotron. Using non-contact laser vibration measurements system OMETRON S16, vibrations in this frequency range were detected on the internal elements of the HF-System. The source of these vibrations, located in the cyclotron bunker, have been identified and removed. In this contribution, the status of the JULIC cyclotron diagnostic system upgrade project will be presented. 899 - ohne Topic (POF4-899) G:(DE-HGF)POF4-899 POF4-899 POF IV 0 Dataset connected to DataCite Accelerator Physics Other Operation and Upgrades Other theory no experiment theory work (theory) EXP:(DE-Ds200)theory-20200803 EXP:(DE-Ds200)no_experiment-20200803 EXP:(DE-Ds200)no_experiment-20200803 0 Felden, Olaf P:(DE-Ds200)OR6694 1 gsi Fröhlich, Nils-Oliver 2 Gebel, Ralf P:(DE-Ds200)OR10305 3 gsi Giesen, Ulrich 4 Lohoff, R. 5 Niedermayer, Philipp P:(DE-Ds200)OR11252 6 gsi Soltner, Helmut 7 Zhang, Tianjue 8 Editor Schaa, Volker R.
