NanoTerasu is a 4th generation 3 GeV light source newly constructed in Sendai, Japan. The circumference is 349 m and the natural emittance is 1.1 nm rad, which is realized by a double-double-bend lattice. The commissioning of the storage ring started in June 2023 and the stored current reached 300 mA in November. The beam diagnostic system for NanoTerasu mainly consists of button BPMs to...
In summer 2024, LIPAc will end its commissioning of Phase B+ after several months of operations. The phase has been focused on the increase of the duty cycle in 5 MeV deuteron operation to validate the different components of the accelerator. The various beam instrumentation systems were tested in depth in order to confirm their performances and limits. The present contribution exposes the...
The China Spallation Neutron Source(CSNS) has launched a power upgrade project this year. The beam power delivering to the target will improve from 100kW to 500kW by five times the beam current while keeping the output energy 1.6GeV unchanged. As the beam current increases, the space charge effect will be enhanced during the RCS injection and initial acceleration process. To suppress this...
The vertical beam size measurement was carried out at BEPCII using a phase grating and an absorption grating based on the Talbot effect. Due to the partial coherence of the source, coherence length can be calculated by measuring the visibility decay of interferograms recorded at different distances behind gratings. The vertical beam size of 68.19±2μm was obtained based on the relationship...
