  The Phase 2 commissioning of SuperKEKB rings with Belle II detector began in Feb. 2018. Staring the commissioning of positron damping ring (DR), the injection and storage of the main rings (HER and LER) smoothly continued in Apr., 2018. The first collision has been achieved on 26th Apr. with the detuned optics (200 mm x 8 mm). Performance of beam instrumentation systems and the difficulties encountered during commissioning time will be shown.

  The ultimate goal of the superconducting LINAC at RISP is to accelerate uranium and proton beams up to 200 MeV/u and 600 MeV, with a maximum beam currents of 8.3 pµA and 660 pµA, respectively. The driver linac is divided into several sections: low energy superconducting linac SCL1 for stable ions and SCL3 for rare isotopes, charge stripper section, and high energy superconducting linac (SCL2). Various types of beam diagnostic devices such as beam current monitor, beam position monitor (BPM), beam profile monitor, beam phase monitor, and beam loss monitor, etc. are required for the setting of accelerator parameters, the monitoring and control of beam acceleration and transport, and improvement of accelerator system. The arrangement of beam diagnostic devices was initially based on the result of beam dynamics calculation, and now the overall layout becomes almost settled. More than 600 devices will be installed for commissioning and normal operation. This report introduces the overall layout of the beam diagnostic system and present status of the system construction.

  Electron beam diagnostics plays a crucial role in the precise and reliable generation of ultra-short high bril-liance XUV and soft X-ray beams at the Free Electron Laser in Hamburg (FLASH). Most diagnostic systems monitor each of up to typically 600 bunches per beam, with a frequency of up to 1 MHz, a typical charge be-tween 0.1 and 1 nC and an energy of 350 to 1250 MeV. The diagnostic monitors have recently undergone a major upgrade. This process started several years ago with the development of monitors fulfilling the requirements of the European XFEL and of the FLASH2 undulator beamline and it continued with their installation and commissioning. Later they have been further improved and an upgrade was made in the old part of the linac. Also the FLASHForward plasma-wakefield acceleration experiment has been installed in the third beamline. This paper will give an overview of the upgrade of the BPM, Toroid and BLM systems, pointing out to their improved performance. Other systems underwent a partial upgrade, mainly by having their VME-based ADCs replaced with MTCA type. The overall status of the diagnostic will be reviewed.

The FRIB Front End and the first three 0.041 cryomodules were successfully commissioned with Argon and Krypton beams. All required beam parameters at the end of the 0.041 cryomodules were reliably demonstrated and exceeded. Installed and commissioned accelerator systems demonstrated stable operation. In this talk, I’ll describe the status of FRIB commissioning and present commissioning results for the FRIB Front End and 0.041 cryomodules.

  The SuperKEKB damping ring (DR) commissioning started in February 2018, before main ring (MR) Phase-II operation. We constructed the DR in order to deliver a low-emittance positron beam. The design luminosity of SuperKEKB is 40 times that of KEKB with high current and low emittance. A turn-by- turn beam position monitor (BPM), transverse feedback system, synchrotron radiation monitor (SRM), DCCT, loss monitor using ion chambers, bunch current monitor and tune meter were installed for beam diagnostics at the DR. An overview of the instrumentation and status will be presented.

  SEE testing of candidate electronic components for space applications is essential part of a spacecraft radiation hardness assurance process in terms of its operability in the harsh space radiation environment. The unique in Russia SEE test facilities have been created to provide SEE testing. The existing ion beam monitoring system has been presented at IBIC 2017, however, it has a number of shortcomings related to the lack of reliable online ion fluence measurement on the DUT, and inability to measure energies of the high-energy (15-60 MeV/nucleon) long-range (10-2000 µm) ions on the DUT. The paper presents the latest developments and their test results of the ISDE and JINR collaboration in the field of flux online monitoring (including, on the DUT) during tests using scintillation detectors based on flexible optical fibers, and measuring ion energies by the method of total absorption in the volume of scintillation or semiconductor detector. The modernization of the standard beam monitoring procedure during tests is proposed.

The Coherent Electron Cooling (CeC) Proof-of-Principle experiment [1], installed in the RHIC tunnel at BNL, has completed its second run. In this experiment, an FEL is used to amplify patterns imprinted on the cooling electron beam by the RHIC ion bunches and then the imprinted pattern is fed back to the ions to achieve cooling of the ion beam. Diagnostics for the CeC experiment have been fully commissioned during this year’s run. An overview of the beam instrumentation is presented, this includes devices for measurements of beam current, position, profile, bunch charge, emittance, as well as gun photocathode imaging and FEL infra-red light emission diagnostics. Design details are discussed and beam measurement results are presented.

  The Coherent electron Cooling (CeC) Proof of Principle Experiment at Brookhaven National Laboratory utilizes a 14 MeV CW electron accelerator and an FEL structure to demonstrate longitudinal cooling of gold ions circulating in the Relativistic Heavy Ion Collider. This unique combination requires proper selection of the diagnostics devices and their parameters. In this paper we present how we transformed design beam parameters into specifications for the instrumentation and hardware configuration. We also have developed tools enhancing diagnostics capabilities including solenoid beam-based alignment and in-line energy measurement. The achieved beam parameters as well as instrument performance are also shown.
