TUP43 | Requirements and Design for the PETRA IV Fast Orbit Feedback System | electron, simulation, feedback, betatron | 343 |
|
|||
PETRA IV is the upcoming low-emittance, 6 GeV, fourth- generation light source at DESY Hamburg. It is based upon a six-bend achromat lattice with additional beamlines as compared to PETRA III. Stringent stability of the electron beam orbit in the ring will be required to achieve diffraction- limited photon beam quality. In this regard, the requirements and the proposed topology of the global orbit feedback system are discussed for expected perturbations. An initial analysis based upon system requirements, design and modelling of the subsystems of the orbit feedback system is also presented | |||

WEP04 | Dual channel FMC High-Voltage Supply | high-voltage, controls, detector, interface | 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. |
