WEP04 | Dual channel FMC High-Voltage Supply | 383 |
|

The Beam Loss Monitoring (BLM) detectors and electronics are installed along the CERN accelerators to provide measurements of the beam loss as well as protection from them when excessive. Majority of the BLM detector types require voltage biasing up to 2000VDC with the possibility to generate voltage modulation patterns to verify the connection chain of the detectors to the front-ends. Currently, the power supply solution consists of COTS large format power supplies with additional custom electronics and various interconnections to provide monitoring and remote control. For this reason, a market search has been done to identify a high reliability module suitable for dedicated BLM installations composed by a few detectors. The outcome of the market search has justified the need to design a low cost custom board, compatible with the CERN infrastructure and different detector types, as well as allow easy customization to cover various installation architectures and voltage range needs. Main characteristics could be summarized with the following points: completely remote controlled and autonomous system, common hardware for different applications, only need to change DC\DC converter.
Other characteristics: few more components for different application and make a model smaller than what is currently used as high voltage power supplies. |

WEP23 | Assessing the Performance of the New Beam Wire Scanners for the CERN LHC Injectors | 443 |
|
||
The ability of reliably measuring the transverse beam profile in its injectors is essential for the operation of the LHC. This report aims to assess the reliability, stability, and reproducibility of the new generation of beam wire scanners developed at CERN in the framework of the LHC Injectors Upgrade (LIU). The study includes data from the over 60000 scans performed in 2021 and 2022, with a special focus on reproducibility, investigation of optimal operational settings to ensure a large dynamic range, and evaluation of absolute accuracy through comparison with other instruments present in the injectors. | ||
