Optimizing the use of pressurized bladders for the assembly of HL-LHC MQXFB magnets

Autor: Troitino, J. Ferradas, Ambrosio, G., Bourcey, N., Cheng, D., Devred, A., Felice, H., Ferracin, P., Guinchard, M., Bermudez, S. Izquierdo, Kandemir, K., Lusa, N., Milanese, A., Mugnier, S., Perez, J. C., Todesco, E., Triquet, S., Vallone, G.

The use of pressurized bladders for stress control of superconducting magnets was firstly proposed at Lawrence Berkeley National Laboratory (LBNL) in the early 2000s. Since then, the so-called bladders and keys procedure has become one of the referen

A Metallurgical Inspection Method to Assess the Damage in Performance-Limiting Nb3Sn Accelerator Magnet Coils

Autor: Moros, Alice, Crouvizier, Mickael Denis, Santillana, Ignacio Aviles, Sgobba, Stefano, Bermudez, Susana Izquierdo, Lusa, Nicholas, Troitino, Jose Ferradas, Milanese, Attilio, Todesco, Ezio, Devred, Arnaud, Ambrosio, Giorgio, Baldini, Maria, Ferracin, Paolo, Schmalzle, Jesse, Vallone, Giorgio

The design and production of Nb3Sn-based dipole and quadrupole magnets is critical for the realization of the High-Luminosity Large Hadron Collider (HL-LHC) at the European Organization for Nuclear Research (CERN). Nb3Sn superconducting coils are aim

On resampling methods for model assessment in penalized and unpenalized logistic regression

Autor: Geroldinger, Angelika, Lusa, Lara, Nold, Mariana, Heinze, Georg

Penalized logistic regression methods are frequently used to investigate the relationship between a binary outcome and a set of explanatory variables. The model performance can be assessed by measures such as the concordance statistic (c-statistic),

Firth's logistic regression with rare events: accurate effect estimates AND predictions?

Autor: Puhr, Rainer, Heinze, Georg, Nold, Mariana, Lusa, Lara, Geroldinger, Angelika

Firth-type logistic regression has become a standard approach for the analysis of binary outcomes with small samples. Whereas it reduces the bias in maximum likelihood estimates of coefficients, bias towards 1/2 is introduced in the predicted probabi
