MOP08 | Development of a Waveguide BPM System | 37 |
|
||
Funding: This work was supported by STFC Follow on Fund grant number ST/T003413/1 A mode-selective waveguide beam position monitor is under development. It is aimed primarily at electron linacs, although with its low impedance and wide bandwidth it could find alternative applications. In this paper we go over the design of the waveguide BPM system including the sensor and analog electronics, consider requirements to the digital processing and present some simulated results. |

MOP09 | Towards Higher Stability in Large Scale Cavity BPM Systems | 40 |
|
||
Funding: This work is supported by Royal Society International Exchanges Grant number IEC\R3\213050 In this contribution we consider a possible solution to long-term stability issues common in cavity BPM systems. The method will see a wider use active in-situ calibration systems injecting a tone into the measurement channel. We plan to compensate the bulk of the beam generated signal and so potentially extend the dynamic range of the electronics, reduce the amount of wakefield seen by the beam. The signal matching the real beam can then be used for mimicking the beam and calibrating out any drifts of the whole sensing and processing chain. We present the concept, give some simulated results and consider possible hardware solutions. |

MOP39 | Development of Compact Radio Frequency Sources | 144 |
|
||
Funding: This work is supported by STFC’s Impact Acceleration Account scheme. Our group is developing a family of compact radio frequency sources aiming to cover 50 MHz to 20 GHz with several models. The primary goal is to provide an alternative to using expensive laboratory generators in permanent installations. In addition, we work towards providing a higher specification than similar telecommunications devices as this is a typical requirement in accelerator instrumentation. We take a minimalistic approach with only a network interface planned, assuming that such a device operates remotely in a large facility. An EPICS interface is in the works for monitoring and control. In this paper, we present the results of rapid prototyping with XMicrowave components. The first measurements show encouraging phase noise performance and spectral purity. |
