11. Technical Aspects of the Dissemination of the Air-Kerma Standard from Cs137 Gamma-Ray Beams in the United States
Published: 10/20/2008
Author: Ronaldo Minniti
Abstract: The national standard for air kerma from gamma-ray beams is maintained in the US by the National Institute of Standards and Technology (NIST), the primary standard dosimetry laboratory in the US. The standard is disseminated throughout the US by a w ...

13. Absorbed Dose to Water Calibration of Ionization Chambers in a ^u60^Co Gamma-Ray Beam
Series: Special Publication (NIST SP)
Report Number: 250-74
Published: 9/1/2006
Authors: Ronaldo Minniti, J Shobe, Stephen Michael Seltzer, Huaiyu H Chen-Mayer, S R Domen
Abstract: Absorbed-dose-to-water calibrations are important to the medical community to facilitate the accurate determination of doses delivered to tumors during external-beam cancer therapy. The first version of this document offered an absorbed-dose-to-water ...

17. In-Situ Observation of Surface Modification Induced by Highly Charged Ion Bombardment
Published: 1/1/2001
Authors: Ronaldo Minniti, John D Gillaspy, L P. Ratliff
Abstract: Nanoscale dots created on the surface of a HOPG sample by bombardment with individual highly charged xenon projectile ions were observed using an in-situ scanning tunneling microscope (STM). This is the first time that such features have been create ...

19. Separation of Inner Shell Vacancy Transfer Mechanisms in Collisions of Slow Ar^u17+^ Ions with SiO^d2^
Published: 1/1/2001
Authors: E Takacs, Z Ber nyi, John D Gillaspy, L P. Ratliff, Ronaldo Minniti, J Pedulla, R Deslattes, N Stolterfoht
Abstract: We have studied the spectrum of x-rays emitted when hydrogen-like argon ions impact silicon dioxide surfaces. Specifically, we were interested in the mechanism for creation of K-shell holes in the silicon target atoms, which can be filled with the r ...
