    Absorbers
    Contributed Oral Presentation

    The Synchrotron SOLEIL is a large-scale research facility in France that provides synchrotron radiation from terahertz to hard X-rays for various scientific applications. To meet the evolving needs of the scientific community and to remain competitive with other European facilities, SOLEIL has planned an upgrade project called SOLEIL II. The project aims to reconstruct the storage ring as a...

    Absorbers
    Contributed Oral Presentation

    In June of 2023, the Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory, Berkeley, California, United States, experienced a vacuum interlock event that caused a beam dump. Upon investigation, the vacuum technicians discovered a leak in the cooling system of a custom photon stop in Sector 5 (12 total). This paper will detail the event, the temporary restoration of...

  3. 13. Cryogenic radiometry: a new absorber for X-rays up to 150 keV (WEOB03)

    Absorbers
    Contributed Oral Presentation

    The accurate measurement of radiant power is essential for the calibration of X-ray detectors, such as silicon photodiodes. Cryogenic electrical substitution radiometers (ESRs) perform high accuracy, absolute, measurements of radiant power. Material and geometry of the absorber in an ESR are chosen to maximize the absorption in the energy range of interest, while providing a high thermal...

  4. 188. CBXFEL design, production, assembly, testing and installation status (WEOB04)
    Xavier Permanyer (SLAC National Accelerator Laboratory)
    17/09/2025, 14:00
    Free Electron Lasers
    Contributed Oral Presentation

    Use of a cavity-based X-ray free electron laser (CBXFEL) is potentially a way to dramatically improve the stability and coherence of existing XFELs. CBXFEL consists of low-emittance electron source, a magnet system with several undulators and chicanes, and an X-Ray cavity. The X-Ray cavity stores and circulates X-ray pulses for repeated FEL interactions with electron pulses until the FEL...

  5. 8. A new RF-contact spring mechanism for exchangeable cathodes in high brightness guns at DESY (WEOB05)
    Frieder Mueller (Deutsches Elektronen-Synchrotron DESY)

    Free Electron Lasers
    Contributed Oral Presentation

    A new 5th generation normal conducting electron gun with improved cell geometry and cooling concept for RF pulse durations of up to 1 ms at 10 Hz repetition rate, and gradients of ~60 MV/m at the cathode was developed and is being tested at the Photo Injector Test Facility at DESY in Zeuthen (PITZ). The cathode is inserted into the back wall of the gun cavity via a load lock system and a RF...
