Minimising Transverse Multipoles in Accelerating RF Cavities via Azimuthally Modulated Designs
/ Wroe, Laurence (JAI, UK) ; Apsimon, Robert (Lancaster U. (main)) ; Dosanjh, Manjit (CERN) ; Sheehy, Suzanne (Melbourne U.)
In this paper, we build upon previous work of designing RF structures that support modes with tailored multipolar fields by applying the concept to negate the transverse multipoles in accelerating RF cavities caused by the incorporation of waveguide slots and tuning deformations. We outline a systematic method for designing structures that minimise these transverse multipoles and present analysis of simulations of two different minimisation designs..

Creating Exact Multipolar Fields in Accelerating RF Cavities via an Azimuthally Modulated Design
/ Wroe, Laurence M (JAI, UK) ; Apsimon, Robert J (Cockcroft Inst. Accel. Sci. Tech.) ; Dosanjh, Manjit (JAI, UK ; CERN) ; Sheehy, Suzanne L (JAI, UK ; Melbourne U.)
In this paper, we present a novel method for designing RF structures with specifically tailored multipolar field contributions. This has a range of applications, including the suppression of unwanted multipolar fields or the introduction of wanted terms, such as for quadrupole focusing. [...]

Collaborative strategies for meeting the global need for cancer radiation therapy treatment systems
/ Dosanjh, Manjit (CERN) ; Aggarwal, Ajay (King's Coll. London) ; Angal-Kalinin, Deepa (Daresbury) ; Apsimon, Robert (Lancaster U. (main)) ; Boogert, Stewart (Royal Holloway, U. of London) ; Burt, Graeme (Lancaster U. (main)) ; Coleman, Norman (Unlisted, US, DC) ; Collier, Paul (CERN) ; Cross, Adrian (Strathclyde U.) ; Konoplev, Ivan (JAI, UK) et al.
The idea of designing affordable equipment and developing sustainable infrastructures for delivering radiation treatment for patients with cancer in countries that lack resources and expertise stimulated a first International Cancer Expert Corps (ICEC) championed, CERN-hosted workshop in Geneva in November 2016. Which has since been followed by three additional workshops involving the sponsorship and support from UK Science and Technology Facilities Council (STFC). [...]

Performance Study of the NIMMS Superconducting Compact Synchrotron for Ion Therapy with Strongly Curved Magnets
/ Norman, Hannah (U. Manchester (main)) ; Appleby, Robert (U. Manchester (main)) ; Benedetto, Elena (U. Geneva (main)) ; Karppinen, Mikko (CERN) ; Owen, Hywel (Daresbury) ; Sheehy, Suzanne (Melbourne U.)
Delivery of heavy ion therapy currently utilises normal conducting synchrotrons. For the future generation of clini- cal facilities, the accelerator footprint must be reduced while adopting beam intensities above 1 × 10¹⁰ particles per spill for more efficient, effective treatment. [...]

The Southern Hemisphere’s First X-Band Radio-Frequency Test Facility at the University of Melbourne
/ Volpi, Matteo (Melbourne U.) ; Boland, Mark J (Saskatchewan U., CLS) ; Catalán Lasheras, Nuria (CERN) ; Dowd, Rohan (ASP, Melbourne) ; González Antón, Sergio (CERN) ; McMonagle, Gerard (CERN) ; Rassool, Roger P (Melbourne U.) ; Sheehy, Suzanne L (Melbourne U.) ; Stapnes, Steinar (CERN) ; Taylor, Geoffrey N (Melbourne U.) et al.
The first Southern Hemisphere X-band Laboratory for Accelerators and Beams (X-LAB) is under construction at the University of Melbourne, and it will operate CERN X-band test stand containing two 12GHz 6MW klystron amplifiers. By power combination through hybrid couplers and the use of pulse compressors, up to 50 MW of peak power can be sent to any of 2 test slots at pulse repetition rates up to 400 Hz. [...]

Review of Technologies for Ion Therapy Accelerators
/ Norman, H X Q (Manchester U. ; RMIT U.) ; Appleby, Robert (Manchester U. ; Daresbury) ; Benedetto, Elena (IBM, Geneva) ; Owen, Hywel (Manchester U. ; RMIT U.) ; Sapinski, Mariusz (IBM, Geneva) ; Sheehy, Suzanne (Melbourne U.) ; Steinberg, A F (Manchester U. ; RMIT U.)
Cancer therapy using protons and heavier ions such as carbon has demonstrated advantages over other radiotherapy treatments. To bring about the next generation of clinical facilities, the requirements are likely to reduce the footprint, obtain beam intensities above 1E10 particles per spill, and achieve faster extraction for more rapid, flexible treatment.

Beam Optics Study for a Potential VHEE Beam Delivery System
/ Robertson, Cameron (JAI, UK) ; Burrows, Philip (JAI, UK) ; Dosanjh, Manjit (CERN) ; Gerbershagen, Alexander (CERN) ; Latina, Andrea (CERN)
VHEE (Very High Energy Electron) therapy can be superior to conventional radiotherapy for the treatment of deep seated tumours, whilst not necessarily requiring the space and cost of proton or heavy ion facilities. Developments in high gradient RF technology have allowed electrons to be accelerated to VHEE energies in a compact space, meaning that treatment could be possible with a shorter linac. [...]
