Analytical and numerical studies of transverse beam splitting used for the CERN PS Multi-Turn Extraction / Hernalsteens, Cedric (CERN)
In view of the programme of reduction of beam losses in the PS for the high intensity beams, in particular that for the CNGS experiment, a novel extraction method was designed for beam transfer between the PS to the SPS. This method, called Multi-Turn Extraction (MTE) is based on the splitting of the proton beam in the horizontal transverse phase space by means of sextupoles and octupoles, using a specific tune variation.

IFJ PAN’s contribution to the HL-LHC: DQW crab cavity preparation and testing at CERN / Zwoźniak, A (Cracow, INP ; CERN) ; Bocian, D (Cracow, INP) ; Krawczyk, A (Cracow, INP ; CERN) ; Prochal, B (Cracow, INP ; CERN) ; Wartak, M (Cracow, INP ; CERN)
The Double Quarter Wave (DQW) Crab Cavity was designed to rotate the colliding bunches and in consequence to increase the luminosity of the LHC machine. Prior to launching series production detailed RF validation tests, both without and with beam, were performed at CERN. [...]

IFJ PAN’s contribution to the HL-LHC: crab cavities and RF / Krawczyk, A (Cracow, INP ; CERN) ; Bocian, D (Cracow, INP) ; Prochal, B (Cracow, INP ; CERN) ; Wartak, M (Cracow, INP ; CERN) ; Zwoźniak, A (Cracow, INP ; CERN)
The High Luminosity LHC (HL-LHC) Project is an upgrade program of the Large Hadron Collider (LHC) at CERN, focused on increasing the luminosity, thus significantly enhancing the potential to discover new physics from rare events. Among many activities ongoing in this framework, the implementation of novel superconducting radio frequency (SRF) cavities - especially Crab Cavities - is foreseen for compensation of the bunch crossing angle, which is a reducing factor for LHC luminosity.

IFJ PAN's contribution to the HL-LHC: construction of the superconducting links / Prochal, B (Cracow, INP ; CERN) ; Bocian, D (Cracow, INP) ; Krawczyk, A (Cracow, INP ; CERN) ; Zwoźniak, A (Cracow, INP ; CERN)
New superconducting transfer lines known as Superconducting Links (SC Links) are being developed at CERN for the remote powering of upgraded superconducting insertion magnets in the framework of the High Luminosity Large Hadron Collider (HL-LHC) project. The purpose of the SC Links is to transfer current from power converters located in radiation-free areas to magnets located in the vicinity of the LHC interaction points via shorter REBCO High Temperature Superconductor (HTS) current leads.

Studies of Higher Order Mode Couplers for the Upgraded Travelling Wave Acceleration System in the CERN SPS / Kramer, Patrick (CERN)
Future high energy particle physics research based on accelerators requires high beam intensity. Parasitic interaction of the charged particle beam with its environment can deteriorate the beam quality and limit the peak intensity for which safe machine operation can be ensured. [...]

Cryogenic Upgrade of the Helium Central Liquefier and Superconducting Cable & Wire Test Facilities at CERN / Pirotte, O (CERN) ; Lees, A (CERN) ; Barbe, T (CERN) ; Dupont, T (CERN) ; Pezzetti, M (CERN)
The demand for liquid helium (LHe) for users at CERN without dedicated cryogenic infrastructure is set to increase due to future projects and experiments in the Antiproton Decelerator. LHe is supplied to the users by means of 500 liter dewars filled by the central liquefier (B165) that comprises a cryogenic plant of 400 W @ 4.5 K. [...]

Design of the consolidated LHC dipole diode busbar insulation system / Meuter, F (CERN) ; Sahner, T (CERN) ; Scheuerlein, C (CERN) ; Tock, J Ph (CERN)
During the second long shutdown of the LHC in 2019 and 2020, the electrical insulation of the 1232 dipole diodes and diode busbars is presently consolidated. The newly designed insulation system, mainly consisting of polyimide laminated fiber reinforced epoxy sheets and injection molded pure resin inserts, can be installed in the very constricted space of the LHC tunnel, without removing the presently installed insulation.
