MC2.A02: Electron linac projects

Invited Talk (Invitation Only)

The inverse Compton scattering (ICS) source based on the collision between high-quality electron beams and laser can generate high-brightness quasi-monoenergetic γ-rays. Our labs have developed a compact MeV quasi-monoenergetic γ-ray ICS source and has successfully commissioned. The VIGAS can generate gamma ray beam with energy can be adjusted from 0.2-4.8MeV, and flux about 10^8...

MC1.A03 Other beams

Invited Talk (Invitation Only)

At Japan Proton Accelerator Research Complex (J-PARC), a low-emittance muon beam based on a linear accelerator is being developed for precision measurements of the muon anomalous magnetic moment (g-2) and electric dipole moment (EDM), as well as for non-destructive imaging applications. In the low-velocity section of the muon linac, a 324-MHz radio-frequency quadrupole linac (RFQ) is employed...

67. New-type high-voltage pulse generator with wide-band rf amplifiers: The principle and application for particle accelerators (FR1A003)

MC4.A05: Other technology

Invited Talk (Invitation Only)

A new-type high-voltage pulse generator by means of a method of frequency-segmented power amplification was proposed and developed. A seed pulse is divided into several lines that have bandpass filters, variable delay lines, variable power attenuators, and main rf amplifiers to correct the frequency-dependent group delays and gain of the amplifier circuit and to perform fine-tuning of the...

MC2.A02: Electron linac projects

Invited Talk (Invitation Only)

CLEAR (CERN Linear Electron Accelerator for Research) is a versatile electron beam user facility operating at CERN, providing beams with energies up to 200 MeV across a broad range of bunch charges, emittances, and timing configurations.
The facility serves a diverse and growing internal and external user community, supporting a wide experimental program spanning multiple domains of...

15. Demonstration of cavity field mapping by falling drops of liquid (FR1A006)

MC4.A04: Low level RF

Invited Talk (Invitation Only)

Experimental mapping of the electric field of a cavity is usually through bead-pull measurements. These require quite long times to align the bead and are generally restricted to the beam axis. Here, the bead has been replaced by drops of liquid falling through the cavity. Together with efficient compression and noise reduction techniques, the method allows for fast and precise measurements....
