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)

Radio-frequency cavity field mapping is conventionally
performed by pulling a perturbing bead through the cavity
on a dielectric wire. Although well established, this procedure requires cavity-specific mechanics and can introduce
perturbations, vibration, and alignment errors. We demonstrate a compact wire-free alternative in which repeatable
liquid drops fall through the cavity under...
