MC9: Overview and Commissioning

Invited Oral Presentation

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...

287. Design of HEPS beam diagnostics (TUBI2)

MC9: Overview and Commissioning

Invited Oral Presentation

HEPS is a fourth generation light source which has horizontal emittance around 34pm.rad and high brilliance photon beam, this ultra-low emittance brings many engineering challenges for beam instrumentation. Self-developed digital BPM electronics and scintillate BLMs contributed more in first turn and day one commissioning. The gird designed by combining carbon fiber and invar alloy have...

127. Beam diagnostics for CSNS-Ⅱ linac commission and operation (TUBC3)

MC9: Overview and Commissioning

Contributed Oral Presentation

The China Spallation Neutron Source (CSNS) facility began operation in 2018. By 2020, its accelerator achieved the design power of 100kW and currently operates at a power of 160kW. This year, the power upgrade project (CSNS-Ⅱ) has been launched to meet the growing scientific demands. Our goal is to enhance the accelerator power to 500kW primarily by increasing the beam current. A...

90. Beam size measurement with gratings at BEPCII (TUBC4)

MC4: Transverse Profile and Emittance Monitors

Contributed Oral Presentation

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...
