MC03: Beam Position Monitors

Invited Oral Presentation

The ALS has been running with an in-house designed Beam Position Monitor for over 10 years. A new design has been developed for the ALS-U project. It includes 8 inputs per pizza-box chassis, an improved Pilot Tone generation for the two button sets, a modular packaging for upgrades and adapting to other machine RF, and improved performance.

The ALS-U BPM uses an AMD Gen3 RFSOC, which...

100. Upgrading Front-End XBPMs for Diamond-II (MORT08)

MC03: Beam Position Monitors

Contributed Oral Presentation

The upgrade of Diamond Light Source to the 4th generation storage ring, Diamond-II, introduces significant changes in the white photon beam properties. Upgrades to the existing XBPM hardware are underway to accommodate increased beam power while maintaining high position sensitivity across beamlines. XBPM blade geometries and positions were optimised using Synchrotron Radiation Workshop (SRW)...

68. Development and characterization of a high-resolution re-entrant cBPM system at the ATF linac (MORT09)

MC03: Beam Position Monitors

Contributed Oral Presentation

A re-entrant cavity beam position monitor (cBPM) has been designed using CST Studio Suite electromagnetic simulations to provide high-resolution spatial measurements for future colliders. This model, operating at 1.630 GHz, offers improved theoretical performance compared to previous prototypes by increasing the normalized shunt impedance (R/Q) and the loaded quality factor (Q_L), which...

61. Development of a novel wide-bandwidth pickup for intrabunch measurements (MORT10)

MC03: Beam Position Monitors

Contributed Oral Presentation

This paper presents the design of a novel semi-coaxial stripline pickup for wide-band beam diagnostics. Four electrodes inside the beam pipe form a quasi-coaxial transmission line that improves electromagnetic field control and provides a smooth impedance transition, mitigating the bandwidth limitations and impedance discontinuities typical of conventional stripline pickups. Electromagnetic...
