MOPORI01	A Multi-Camera System for Tomographic Beam Diagnostics	215
	A. Ateş, G. Blank, H. Hähnel, U. Ratzinger IAP, Frankfurt am Main, Germany
	A prototype of a beam-induced residual gas fluorescence monitor (BIF) has been developed and successfully tested at the Institute of Applied Physics (IAP) of the Goethe University Frankfurt. This BIF is based on ten single-board cameras inserted into the vacuum and directed onto the beam axis. The overall goal is to study the beam with tomography algorithms at a low energy beam transport section. Recently, we tested the detector with a 60keV, 15mA proton beam at 20Hz and 1ms puls length. In this paper we present the ongoing investigations on image processing and application of the algebraic reconstruction technique (ART).

MOPORI02	Implementation of an Advanced MicroTCA.4-based Digitizer for Monitoring Comb-Like Beam at the J-PARC Linac	219

	The Japan Proton Accelerator Research Complex (J-PARC) linac beam pulse, generated by a beam chopper system placed at the MEBT, comprises a series of intermediate pulses with a comb-like structure synchronized with the radio-frequency of the rapid cycling synchrotron (RCS). The sequentially measuring and monitoring the comb-like beam pulse ensures the beam stability with less beam loss at the current operation and higher beam intensity scenarios at the J-PARC. However, signal processing as a function of the pulse structure is challenging using a general-purpose digitizer, and monitoring the entire macro pulse during the beam operation is unavailable. To this end, an advanced beam monitor digitizer complying with the MicroTCA.4 (MicroTelecommunications Computing Architecture.4) standard, including digital signal processing functions, has been developed. This paper reports the implementation, performance evaluation, and the first results of this unique beam monitor digitizer.

MOPORI03	Development of Quantum Gas Jet Beam Profile Monitor for Sub-mm Beams	223

The development work of a high-resolution quantum gas jet beam profile monitor for highly energetic sub-mm particle beams is in progress at the Cockcroft Institute (CI), UK. This device is designed on the principle of detecting the secondary ions from the ionisation induced in the interaction between the quantum gas jet and charged particle beams. This monitor aims to generate an intense gas jet with a diameter of less than 100 µm, which can ultimately lead to superior position resolution and high signal intensity resulting from a strongly focused quantum gas jet. This is done by exploiting the quantum wave feature of the neutral gas atoms to generate an interference pattern with a single maximum acting as an ultra-thin gas jet using an ’atom sieve’ which is similar to the light focusing with a Fresnel zone plate. This device will be minimally interceptive and will work analogously to a mechanical wire scanner. This contribution gives a general overview of the design, working principle of the monitor and experimental results obtained from the electron beam profile measurements carried out at the Cockcroft Institute.

MOPORI04	A Gas Jet Beam Halo Monitor for LINACs	227

	The gas jet beam profile monitor is a non-invasive beam monitor that is currently being commissioned at the Cockcroft Institute. It utilises a supersonic gas curtain which traverses the beam perpendicular to its propagation and measures beam-induced ionisation interactions of the gas. A 2D transverse beam profile image is created by orientating the gas jet 45 degrees to obtain both X and Y distributions of the beam. This paper builds upon previously used single-slit skimmers and improves their ability to form the gas jet into a desired distribution for imaging beam halo. A skimmer device removes off-momentum gas particles and forms the jet into a dense thin curtain, suitable for transverse imaging of the beam. The use of a novel double-slit skimmer is shown to provide a mask-like void of gas over the beam core, increasing the relative intensity of the halo interactions for measurement. Such a non-invasive monitor would be beneficial to linacs by providing real time beam characteristic measurements without affecting the beam. More specifically, beam halo behaviour is a key characteristic associated with beam losses within linacs.

MOPORI05	Application of Virtual Diagnostics in the FEBE Clara User Area	231

	Funding: This work is supported by the AWAKE-UK phase II project funded by STFC and the STFC Cockcroft core grant No. ST/G008248/1. Successful user experiments at particle beam facilities are dependent upon the awareness of beam characteristics at the interaction point. Often, properties are measured beforehand for fixed operation modes; users then rely on the long-term stability of the beam. Otherwise, diagnostics must be integrated into a user experiment, costing resources and limiting space in the user area. This contribution proposes the application of machine learning to develop a suite of virtual diagnostic systems. Virtual diagnostics take data at easy to access locations, and infer beam properties at locations where a measurement has not been taken, and often cannot be taken. Here the focus is the user area at the planned Full Energy Beam Exploitation (FEBE) upgrade to the CLARA facility (UK). Presented is a simulation-based proof-of-concept for a variety of virtual diagnostics. Transverse and longitudinal properties are measured upstream of the user area, coupled with the beam optics parameters leading to the user area, and input into a neural network, to predict the same parameters within the user area. Potential instrumentation for FEBE CLARA virtual diagnostics will also be discussed.

For supersonic gas jet based beam profile monitors such as that developed for the High Luminosity Large Hadron Collider (HL-LHC) upgrade, density profile is a key characteristic. Due to this, non-invasive diagnostics to study the jet’s behaviour have been designed. A Nomarski interferometer was constructed to image jets 30 um to 1 mm in diameter and study changes in their density. A microscope lens has been integrated into the original interferometer system to capture phase changes on a much smaller scale than previous experiments have achieved. This contribution presents the optimisation and results gained from this interferometer.
