TUAO01 | Beam Diagnostics for Studying Beam Losses in the LHC | detector, proton, collimation, feedback | 222 |

|||
The LHC is well covered in terms of beam loss instrumentation. Close to 4000 ionisation chambers are installed to measure global beam losses all around the LHC ring, and diamond detectors are placed at specific locations to measure bunch-by-bunch losses. Combining the information of these loss detectors with that from additional instrumentation, such as current transformers, allows for enhanced understanding and control of losses. This includes a fast and reliable beam lifetime calculation, the identification of the main origin of the loss (horizontal or vertical betatron motion or off-momentum), or a feedback to perform controlled off-momentum loss maps to validate the settings of the collimation system. This paper describes the diagnostic possibilities that open up when such measurements from several systems are combined.
This is proposed as an Invited presentation from CERN Beam Instrumentation Group. |

TUAO03 | Beam Loss Measurements Using the Cherenkov Effect in Optical Fiber for the BINP e−e+ Injection Complex | electron, extraction, radiation, injection | 233 |
|
|||
Optical fiber based beam loss monitor (OFBLM) has been developed for the 500 MeV BINP Injection Complex (IC). Such monitor is useful for accelerator commissioning and beam alignment, and allows real-time monitoring of e−e+ beam loss position and intensity. Single optical fiber (OF) section can cover the entire accelerator instead of using a large number of local beam loss monitors. In this paper brief OFBLM selection in comparison with other distributed loss monitors was given. Methods to improve monitor spatial resolution are discussed. By selecting 45 m long silica fiber (with a large core of 550 um) and microchannel plate photomultiplier (MCP-PMT), less than 1 m spatial resolution can be achieved. | |||
