A Radiation-Tolerant 25.6-Gb/s High-Speed Transmitter in 28-nm CMOS With a Tolerance of 1 Grad
/ Klekotko, A (CERN ; Leuven U.) ; Biereigel, S (CERN) ; Baszczyk, M (CERN) ; Moreira, P (CERN) ; Martina, F (CERN) ; Prinzie, J (Leuven U.) ; Kulis, S (Leuven U.)
This article presents a 25.6-Gbit $\cdot $ s−1 high-speed transmitter (HST) manufactured using 28-nm CMOS technology. The HST macroblock includes an all-digital phase-locked loop (ADPLL), duty cycle corrector (DCC) circuit, data pattern generator, serializer, and a driver capable of driving the differential 100- $\Omega $ line as well as a silicon photonics (SiPh) ring modulator (RM).

Status of CLIC Magnets Studies and R
/ Modena, Michele (CERN) ; Aloev, Alexander (CERN) ; Solodko, Evgeny (CERN) ; Thonet, Pierre-Alexandre (CERN) ; Vorozhtsov, Alexey (CERN)
Since 2009 the CERN Magnet Group (CERN-TE-MSC) started R&D; activities in order to focalize the most challenging and interesting cases to be studied among the magnets needed for CLIC the Compact Linear Collider. In the last four years several theoretic studies, models and prototypes were realized mainly in two domains: magnets for the Modules, the modular elements that are composing the backbone of the two-beam linac structure of CLIC, and the Machine Detector Interface (MDI) including the Final Focus elements, and the anti-solenoid.

Designing the Muon System of a Muon Collider Experiment: Requirements from Muon Reconstruction and Technological Solutions
/ Aimè, C (Pavia U. ; INFN, Pavia) ; Bartosik, N (INFN, Turin) ; Casarsa, M (INFN, Trieste ; Trieste U.) ; Riccardi, C (Pavia U. ; INFN, Pavia) ; Salvini, P (INFN, Pavia) ; Vai, I (Bergamo U., Ingengneria Dept. ; INFN, Pavia)
A promising proposal for the future of particle acceleration is represented by the muon collider. Indeed, it would give the possibility to probe much higher energy scales than hadrons colliding at the same energy, with a greatly reduced pile up effect. [...]

Flux Concentrator Optimization for Future Positron Sources
/ Bajas, H (CERN) ; Doebert, S (CERN) ; Latina, A (CERN) ; Zhao, Y (CERN)
Future lepton colliders, such as CLIC, FCC-ee or ILC require high quality positron sources. Positrons are created after the collision of electrons on a tungsten target and then focused to match the aperture of the capture structures with a flux concentrator (FC) often called an Adiabatic Matching Device (AMD), a strong pulsed magnet.

Simulation Studies of Intra-Train, Bunch-by-Bunch Feedback Systems at the International Linear Collider
/ Ramjiawan, Rebecca (JAI, UK ; CERN) ; Bett, Douglas (JAI, UK ; CERN) ; Bodenstein, Ryan (Jefferson Lab ; JAI, UK) ; Burrows, Philip (JAI, UK) ; Christian, Glenn (Diamond Light Source ; JAI, UK) ; Perry, Colin (JAI, UK)
The International Linear Collider (ILC) is a proposed electron-positron collider targeting collision energies from 250 GeV to 1 TeV. With design luminosities of order 10³⁴ cm²s⁻¹, a beam-based, intra-train feedback system would be required near the Interaction Point (IP) to provide nanometre-level stabilisation of the beam overlap in the collisions.
