	Funding: This work was done under the auspices of CHART (chart.ch) This paper is an overview of a diagnostics setup for highly spread e⁺e⁻ beams, to be installed at the PSI Positron Production (P³ or P-cubed) experiment. To be hosted at the SwissFEL facility (PSI, Switzerland) in 2026, P³ is e⁺ source demonstrator designed to generate, capture, separate and detect nano-Coulombs of secondary e⁺ and e^- bunches, in spite of their extreme tranverse emittance and energy spread. The experiment will employ an arrangement of broadband pick-ups (BBPs) to detect simultaneously the time structure of secondary e⁺e⁻ bunches. A spectrometer will follow the BBPs and deflect the e⁺ and e^- onto two unconventional faraday cups that will measure their charge. In addition, the energy spectrum of e⁺ and e^- distribution will be reconstructed through scintillating fibers.

MOP013	Expansion of the MTCA Based Direct Sampling LLRF at MedAustron for Hadron Synchrotron Applications	synchrotron, diagnostics, injection, hadron	63

	The MedAustron Ion Therapy Centre is a synchrotron-based particle therapy facility located in Lower Austria, which delivers proton and carbon ion beams for cancer treatments. Currently the facility treats over 400 patients per year and is expected to double this number in the future. Six years since the start of clinical operation, MedAustron is experiencing end-of-life issues concerning the digital Low Level RF components in the injector and the synchrotron. Replacements for these applications are under development and the chosen hardware is suitable to also update multiple beam diagnostic devices in the facility. Main targets for updates are the Schottky monitors, which were never properly integrated into the MedAustron Control system and the position pickup measurement system, which currently does not support turn by turn measurements. Comparison measurements with other state of the art diagnostic devices are ongoing to demonstrate the capabilities of the generic hardware. Furthermore, these measurements should show the increased usability and diagnostic potential compared to the legacy devices.

MOP032	One Dimensional Beam Position Monitor Prototype using Incoherent Cherenkov Diffraction Radiation	radiation, electron, experiment, vacuum	94
	A.J. Clapp Royal Holloway, University of London, Surrey, United Kingdom L. Bobb, G. Cook DLS, Oxfordshire, United Kingdom P. Karataev JAI, Egham, Surrey, United Kingdom
	This paper proposes a novel advancement in both the studies of Cherenkov diffraction radiation (ChDR) and beam instrumentation. The proposed beam position monitor (BPM) consists of two identical fused Silica prism radiators, with a fibre collimator attached to each one, which in turn are connected to a photodetector via a series of optical fibres. The setup will be implemented into the booster to storage ring transfer line at Diamond Light Source ¿ an electron light source with 3 GeV beam energy. The prototype proposed aims to test the feasibility of a full BPM utilising ChDR. If proven to be fully realisable, optical rather than capacitive BPM pickups could be more widely distributed. The paper will include the complete design and preliminary results of a one-dimensional BPM, utilising the ChDR effect.

TUP012	First Measurements of an Electro-Optical Bunch Arrival-Time Monitor Prototype with PCB-Based Pickups for ELBE	electron, laser, free-electron-laser, FEL	214

	Funding: This work is supported by the German Federal Ministry of Education and Research (BMBF) under Contract No. 05K19RO1 and 05K22RO2. A vacuum sealed prototype of an electro-optical bunch-arrival-time monitor has been commissioned in 2023. It comprises of a pickup-structure and a low-pi-voltage ultra-wideband traveling wave electro-optical modulator. The stainless-steel body of the pickup structure is partially produced by additive manufacturing and comprises four pickups as well as an integrated combination network on a printed circuit board. This novel design aims to enable single-shot bunch-arrival-time measurements for electron beams in free-electron lasers with single-digit fs precision for low bunch charges down to 1 pC. The theoretical jitter charge product has been estimated by simulation and modeling to be in the order of 9 fs pC. The new prototype is tailored for validation experiments at the ELBE accelerator beamline. In this contribution first measurement results are presented.

TUP034	Axial Cryogenic Current Comparator (CCC) for FAIR	detector, cryogenics, shielding, resonance	259

	Funding: Work supported by the BMBF under contract No. 05P21SJRB1. The Cryogenic Current Comparator (CCC) is a superconducting device based on an ultrasensitive SQUID (fT range). Measuring the beam¿s azimuthal magnetic field, it provides a calibrated non-destructive measurement of beam current with a resolution of 10 nA or better, independent from ion species and without tedious calibrations procedure. The non-interceptive absolute intensity measurement of weak ion beams (< 1 µA) is essential in heavy ion storage rings and in transfer lines at FAIR. With standard diagnostics, this measurement is challenging for bunched beams and virtually impossible for coasting beams. To improve the performance of the detector several upgrades are under study and development: One is the investigation of a new type of CCC using an alternative magnetic shield geometry. The so-called ‘axial¿ geometry will allow for much higher magnetic shielding factor, an increased pick-up area, and a lower low frequencies noise component. Further improvements and optimizations of the detector will be presented. The CCC will be tested on the beamline at the end of 2023 allowing to define the best possible version for FAIR.

TUP036	Cryogenic Current Comparators as Low Intensity Diagnostics for Ion Beams	shielding, cryogenics, detector, electron	268

Zakosarenko Supracon AG, Jena, Germany
	The Cryogenic Current Comparator (CCC) is a SQUID based superconducting device for intensity measurement, firstly proposed as a beam diagnostics instrument in the 90s at GSI. After prove of principle the CCC was introduced into other facilities, attesting great potential for high resolution measurements but at the same time considerable mechanical and cryogenics challenges and costs. In the course of plannings for FAIR the CCC has been revitalized. Systematic investigations started, involving commercially available SQUID systems, which led to improvements of detector and cryostat. The developments resulted in nA spill measurements at GSI (2014) followed by the installation of a CCC in CERN Antiproton Decelerator (AD), which has in the meantime become a key instrument. Since then optimization of the device is ongoing, with respect to various operating conditions, system robustness, current resolution and last but not least system costs. Alternative CCC versions with improved magnetic shielding have been developed as well as ¿Dual Core‘ versions for background noise reduction. We give an overview of CCC optimization and development steps, with focus on applications at GSI and FAIR.

WEP033	A Schottky Tune Meter for the Fermilab Mu2E Delivery Ring	FPGA, proton, experiment, extraction	425
	V.E. Scarpine, B.J. Fellenz, A. Semenov, D. Slimmer Fermilab, Batavia, Illinois, USA
	Funding: This work was supported by the U.S. Department of Energy under contract No. DE-AC02-07CH11359. The Mu2E experiment will measure the ratio of the rate of the neutrinoless, coherent conversion of muons into electrons as a measure of Charged Lepton Flavor Violation. As part of the Mu2E experiment, a proton storage ring, called the Delivery Ring, will utilize resonant extraction to slow-spill protons to the experiment. To regulate and optimize the Delivery Ring resonant extraction process, a fast tune measurement scheme will be required. This Mu2E tune meter will measure the average tune and the tune spectrum, in multiple time slices, through the entire resonant extraction cycle of nominally 43 msec. The Mu2E tune meter utilizes vertical and horizontal 21.4 MHz Schottky detector resonant pickups, taken from the decommissioned Tevatron, as well as its receiver electronics. This paper will present the design of this Schottky tune meter as well as tune measurements from the Mu2E Delivery Ring.
