Linear Paul trap design for an optical clock with Coulomb crystals

, 2011
We report on the design of a segmented linear Paul trap for optical clock applications using trapped ion Coulomb crystals. For an optical clock with an improved short-term stability and a fractional frequency uncertainty of 10^-18, we propose 115In+ ions

Analysis of dissipated energy and temperature fields at severe notches of AISI 304L stainless steel specimens

Fracture and Structural Integrity, 2018
In the last years, a large amount of fatigue test results from plain and bluntly notched specimens made of AISI 304L stainless steel were synthetized in a single scatter band by adopting the specific heat loss per cycle (Q) as a damage parameter.

Program Fatigue Test and Notch Effect

Journal of the Society of Materials Science, Japan, 1964
A definition of the notch factor associated with program fatigue test, is proposed in the present study and some hypothesis are presented as to how to estimate the notch factor from the conventional fatigue tests.The conclusions are as follows: The notch factor may be estimated as the highest value among the values of the notch factor that we can ...
