Renaissance of the ~1 TeV Fixed-Target Program (2009)

Adams, T., Appel, J. A., Arms, K. E., Balantekin, A. B., Conrad, J. M., Cooper, P. S., ...

This document describes the physics potential of a new fixed-target program based on a ~1 TeV proton source. Two proton sources are potentially available in the future: the existing Tevatron at...

LHC Symposium 2003: Summary Talk (2003)

Appel, J A

This summary talk reviews the LHC 2003 Symposium, focusing on expectations as we prepare to leap over the current energy frontier into new territory. We may learn from what happened in the two most...

Asymmetries in the Production of Lambda0 in 250 GeV/c pi+-, K+- and p -- Nucleon Interactions (2003)

Alves, G. A., Amato, S., Anjos, J. C., Appel, J. A., Astorga, J., Bernard, T., ...

Using data from Fermilab fixed-target experiment E769, we have measured particle-antiparticle production asymmetries for Lambda0 hyperons in 250 GeV/c pi+-, K+- and p -- nucleon interactions. The...

Characterization of Prototype BTeV Silicon Pixel Sensors Before and After Irradiation (2002)

Coluccia, Maria R., Appel, J. A., Chiodini, G., Christian, D. C., Kwan, S.

We report on measurements performed on silicon pixel sensor prototypes exposed to a 200 MeV proton beam at the Indiana University Cyclotron Facility. The sensors are of n+/n/p+ type with multi-guard...

Single Event Effects in the Pixel readout chip for BTeV (2001)

Chiodini, G., Appel, J. A., Cardoso, G., Christian, D. C., Coluccia, M. R., Hoff, J., ...

In future experiments the readout electronics for pixel detectors is required to be resistant to a very high radiation level. In this paper we report on irradiation tests performed on several...

Performance of prototype BTeV silicon pixel detectors in a high energy pion beam (2001)

Appel, J. A., Artuso, M., Butler, J. N., Cancelo, G., Cardoso, G., Cheung, H., ...

The silicon pixel vertex detector is a key element of the BTeV spectrometer. Sensors bump-bonded to prototype front-end devices were tested in a high energy pion beam at Fermilab. The spatial...

Beam Test of BTeV Pixel Detectors (2000)

Wang, J. C., Appel, J. A., Artuso, M., Butler, J. N., Cancelo, G., Cardoso, G., ...

The silicon pixel vertex detector is one of the key elements of the BTeV spectrometer. Detector prototypes were tested in a beam at Fermilab. We report here on the measured spatial resolution as a...

Beam Test Results of the BTeV Silicon Pixel Detector (2000)

Chiodini, G., Appel, J. A., Artuso, M., Butler, J. N., Cardoso, G., Cheung, H., ...

The results of the BTeV silicon pixel detector beam test carried out at Fermilab in 1999-2000 are reported. The pixel detector spatial resolution has been studied as a function of track inclination,...

Asymmetries between the production of D+ and D- mesons from 500 GeV/c pi- nucleon interactions as a function of xF and pt**2 (1996)

Aitala, E. M., Amato, S., Anjos, J. C., Appel, J. A., Aryal, M., Ashery, D., ...

We present asymmetries between the production of D+ and D- mesons in Fermilab experiment E791 as a function of xF and pt**2. The data used here consist of 74,000 fully-reconstructed charmed mesons...

Pathogenicity and Reproduction of Hoplolaimus columbus and Meloidogyne incognita on 'Davis' Soybean

Appel, J. A., Lewis, S. A.

The effects of initial populations of Hoplolaimus columbus and Meloidogyne incognita on growth and yield of Davis soybean were determined for 1980 and 1981 in microplots and H. columbus in field...
