Performance studies of the CMS Strip Tracker before installation (2009)

Adam, W, Bergauer, T, Dragicevic, M, Friedl, M, Frühwirth, R, Hansel, S, ...

In March 2007 the assembly of the Silicon Strip Tracker was completed at the Tracker Integration Facility at CERN. Nearly 15% of the detector was instrumented using cables, fiber optics, power...

H.P.: Parallel programmability and the Chapel language (2007)

B. L. Chamberlain, B. L. Chamberlain, D. Callahan, D. Callahan, H. P. Zima, H. P. Zima

In this paper we consider productivity challenges for parallel programmers and explore ways that parallel language design might help improve end-user productivity. We offer a candidate list of...

BABAR silicon vertex tracker: Status and prospects (2006)

Re, V, Bondioli, M, Bruinsma, M, Curry, S, Kirkby, D, Berryhill, J, ...

The BABAR Silicon Vertex Tracker (SVT) has been efficiently operated for six years since the start of data taking in 1999. Due to higher than expected background levels some unforeseen effects have...

The BABAR detector (2006)

Aubert, B., Bazan, A., Boucham, A., Boutigny, D., De Bonis, I., Favier, J., ...

BABAR, the detector for the SLAC PEP-II asymmetric e+e- B Factory operating at the upsilon 4S resonance, was designed to allow comprehensive studies of CP-violation in B-meson decays. Charged...

Radiation damage studies for the BABAR silicon vertex tracker (2005)

Re, V., Kirkby, D., Bruinsma, M., Berryhill, J., Burke, S., Callahan, D., ...

The Silicon Vertex Tracker of the BABAR experiment is a five-layer, double-sided AC-coupled silicon microstrip detector operating on the PEP-II storage ring at the Stanford Linear Accelerator Center....

The Modular Point Design for Heavy Ion Fusion (2004)

Yu, S.S., Barnard, J.J., Briggs, R.J., Callahan, D., Celata, C.M., Chao, L., ...

We report on an ongoing study on modular Heavy Ion Fusion drivers. The modular driver is characterized by 10 to 20 nearly identical induction linacs, each carrying a single high current beam. In this...

Frustrated mastery. The cultural context of death in America.

Callahan, D

The care of dying patients as a problem in the United States cannot be well understood apart from understanding the way in which American culture has responded to the problem of death. This country...

Principlism and communitarianism

Callahan, D

The decline in the interest in ethical theory is first outlined, as a background to the author's discussion of principlism. The author's own stance, that of a communitarian philosopher, is then...
