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).

Prototype measurement results in a 65 nm technology and TCAD simulations towards more radiation tolerant monolithic pixel sensors
/ Lemoine, C (CERN ; Strasbourg, IPHC) ; Aglieri Rinella, G (CERN) ; Baudot, J (Strasbourg, IPHC) ; Borghello, G (CERN) ; Carnesecchi, F (CERN) ; Hillemanns, H (CERN) ; Kluge, A (CERN) ; Kucharska, G (CERN) ; Leitao, P V (CERN) ; Mager, M (CERN) et al.
Early measurements on monolithic pixel sensor prototypes in the TPSCo 65 nm technology indicate a different response and radiation tolerance (up to5×10$^{15}$ 1 MeV n$_{eq}$ cm) for different sensor layout and process variants, illustrating the importance of layout and process in the path towards increased sensor radiation tolerance. Using these measurement results, TCAD simulations provide more insight to link the macroscopic behaviour of specific sensor variants to the details of its structure. [...]

Computational investigation of transport parameters of ions in gas-filled radiation detectors
/ Kalkan, Yalçın (Abant Izzet Baysal U. ; CERN ; Mus Alparslan U.) ; Arı, Sedat (Abant Izzet Baysal U. ; CERN) ; Orak, Salim (Unlisted, TR) ; Veenhof, Rob (CERN)
In this study, a novel computational method was developed toinvestigate the transport characteristics of ions in gas-filledradiation detectors, which are closely linked to the behavior ofions in gaseous detectors. Parameters such as polarizability, meanfree path, collision frequency, and mean free time, which directlyimpact ion mobility, were physically manipulated using the MonteCarlo technique, and the results were validated against fundamentalphysical principles.

The 100 Tm superconducting synchrotron SIS100 is the main accelerator of the international Facility for Antiproton and Ion Research (FAIR) currently under advanced construction in Darmstadt, Germany. The SIS100 dipole circuit which creates the magnetic field required to bend the beam, consists of 108 dipoles distributed over six arc sections of the ring. [...]

Proof-of-Principle of an Energy-Efficient, Iron-Dominated Electromagnet for Physics Experiments
/ Devred, A (CERN) ; Ballarino, A (CERN) ; Bourcey, N (CERN) ; Mangiarotti, F (CERN) ; Milanese, A (CERN) ; Petrone, C (CERN)
A number of physics experiments call for the use of iron-dominated, normal-conducting electromagnets to produce moderate fields (2 T range) in a large gap or over a large volume. Although robust and reliable, these magnets require significant electrical power, in the MW range, and can thus be costly to operate, especially in DC mode. [...]

Quench Protection of Fusillo Subscale Curved CCT Magnet
/ Wozniak, M (CERN) ; Haziot, A (CERN) ; Mangiarotti, F J (CERN) ; Ravaioli, E (CERN) ; Ferriere, R (CERN) ; Guardia-Valenzuela, Jorge (CERN) ; Foussat, A P (CERN) ; Kirby, G (CERN) ; Verweij, A (CERN)
The Fusillo project at CERN aims to design and build a demonstrator magnet with multi-harmonic corrected fields in a 90° curved CCT magnet. In the first stage, a subscale magnet is built with 30° bending, about 1/30 of the demonstrator conductor length, and increased current to reach coil stresses equivalent to the demonstrator. [...]
