Microstructural Characterization of Nb3Sn Thin Films Using FIB Tomography
Eric Viklund, David N. Seidman, Sam Posen
The accelerating gradient of Nb3Sn superconducting radiofrequency (SRF) cavities is currently limited, and the underlying cause remains an open question in the field. One leading h…
Status of the International Linear Collider
Y. Abe, S. Arai, S. Araki +149
This paper is not a proposal for a CERN future project but provides information on the International Linear Collider (ILC) considered for Japan in order to facilitate the European…
A Linear Collider Vision for the Future of Particle Physics
H. Abramowicz, E. Adli, F. Alharthi +446
In this paper we review the physics opportunities at linear colliders with a special focus on high centre-of-mass energies and beam polarisation, take a fresh look at the…
Analysis of Niobium Electropolishing Using a Generalized Distribution of Relaxation Times Method
Eric Viklund, Vijay Chouhan, Davida Smith +3
Using electrochemical impedance spectroscopy, we have devised a method of sensing the microscopic surface conditions on the surface of niobium as it is undergoing an electrochemica…
Healing Gradient Degradation in Nb3Sn SRF Cavities Using a Recoating Method
Eric Viklund, David N. Seidman, Brad M. Tennis +2
Despite having advantageous superconducting properties, Nb3Sn superconducting radiofrequency (SRF) cavities still have practical challenges compared to Nb SRF cavities due to the b…
Improving Nb3Sn Cavity Performance Using Centrifugal Barrel Polishing
Eric Viklund, David N. Seidman, David Burk +1
In this study we will show a new method of polishing for Nb3Sn cavities known as centrifugal barrel polishing (CBP). Using this method, Nb3Sn coated samples are polished to a surfa…
