Future Challenges in Particle Physics Education and Outreach
This document is meant to serve as input from the IPPOG Collaboration for the open call for the European Particle Physics Strategy Update 2020. It emphasises the strategic relevance of concerted, global outreach activities in particle physics today and beyond when envisaging new large-scale projects..

Integrated modeling of the beam formation and extraction in the Linac4 hydrogen negative ion source
/ Nishioka, S (Keio U.) ; Abe, S (Keio U.) ; Mattei, S (CERN) ; Lallement, J B (CERN) ; Kalvas, T (Jyvaskyla U.) ; Hatayama, A (Keio U.) ; Lettry, J (CERN)
In order to make the predictive simulation tools for the extracted beam current and emittance in the Linac4 H− ion source, we have launched the development of the integrated model for the H− ion beam formation and extraction process. More specifically, our 3D KEIO-Beam Formation and eXtraction (3D KEIO-BFX) is coupled with the NINJA, IBSIMU and TRAVEL. [...]

Charge breeding of CO$^{+}$ beams at REX-ISOLDE
/ Pitters, J (CERN) ; Breitenfeldt, M (CERN) ; Wenander, F (CERN)
The β+ emitter 11C is a possible treatment ion for hadron therapy owing to its excellent properties in PET imaging, which could be used for range verification during the treatment. A charge breeder is required to transform the molecular CO+ beam, coming from an ISOL-production stage (Isotope Separation OnLine), to Cn+ and to match it with the acceptance of the medical accelerator. [...]

Plasma impedance prediction model and impedance matching by frequency tuning in radio frequency negative ion sources
/ Kobayashi, W (Keio U.) ; Nishida, K (Keio U.) ; Mattei, S (CERN) ; Lettry, J (CERN) ; Hatayama, A (Keio U.)
A radio frequency (RF) driven type hydrogen (H−) source is used as an injector of Linac4. The power transfer efficiency between the RF generator and the ion source plasma is one of the important parameters that determines the extracted H− beam current. [...]

Numerical analysis of ion dynamics in RF ICP discharge
/ Nishida, K (Keio U.) ; Mattei, S (CERN) ; Kobayashi, W (Keio U.) ; Lettry, J (CERN) ; Hatayama, A (Keio U.)
We have worked on the development of a particle-based numerical model of a hydrogen Radio Frequency (RF) Inductively Coupled Plasma (ICP). In the previous work, it has been shown that the model is able to simulate the E-to-H discharge mode transition, which is one of the distinct features of RF ICP. [...]

MEDeGUN commissioning results
/ Breitenfeldt, M (CERN) ; di Lorenzo, F (CERN) ; Pikin, A (Brookhaven Natl. Lab.) ; Pitters, J (CERN) ; Wenander, F (CERN)
MEDeGUN [1] is an electron gun to be used in an Electron Beam Ion Source (EBIS) designed to serve as C6+ source for LINAC-based 2nd generation hadron therapy facilities [2]. The latter require short pulses of at least 1*108 particles at a repetition rate of 400 Hz, which exceeds the possibilities of currently used electron cyclotron resonance ion sources (ECRIS) and EBISes.

Linac4 source extraction and low energy beam transport study
/ Noll, D (CERN) ; Bencini, V (CERN) ; Lallement, J B (CERN) ; Lettry, J (CERN) ; Lombardi, A M (CERN) ; Lorenzo, F Di (CERN) ; Mattei, S (CERN) ; O'Neil, M (CERN)
In the framework of the LHC Injector Upgrade program, a new normal conducting linac (Linac4) operating at the frequency of 352 MHz has been recently commissioned to the final energy of 160 MeV. Linac4 will be connected to the LHC injector chain in 2020 and it is expected to provide a 40 mA, 400 µs H− beam for charge-exchange injection into the Proton Synchrotron Booster. [...]
