A High-Power Test of an X-Band Molybdenum-Iris Structure (2004)

Wuensch, Walter, Döbert, Steffen, Grudiev, A, Heikkinen, Samuli Tapio, Syratchev, I V, Taborelli, M, ...

In order to achieve accelerating gradients above 150 MV/m, alternative materials to copper are being investigated by the CLIC study. The potential of refractory metals has already been demonstrated...

Stability Considerations for Final Focus Systems of Future Linear Colliders (2000)

Assmann, R W, Jeanneret, J B, Verdier, A, Vos, L, Wildner, E, Zimmermann, Frank, ...

The final focus systems for the future linear colliders need to focus beams to nm-range spot sizes at the collision point. The design spot size varies from several nm for 500 GeV to the one nm range...

Beam Current Monitors in the Nlcta (2000)

Nantista, C D, Adolphsen, C E

The current profile along the 126 ns, multi-bunch beam pulse in the Next Linear Collider Test Accelerator (NLCTA) is monitored with fast toroids (rise time ~1 ns). Inserted at several positions along...

Physics and technology of the Next Linear Collider (2000)

Kuhlman, S, Adolphsen, C E, Aiello, R, Akemoto, M, Alley, R, Assmann, R W, ...

We present the current expectations for the design and physics program of an e+e- linear collider of center of mass energy 500 GeV -- 1 TeV. We review the experiments that would be carried out at...

A reanalysis of B0-B0 mixing in e+e- annihilation at 29 GeV (1990)

Weir, A. J., Abrams, G., Adolphsen, C. E., Alexander, J. P., Alvarez, M., Amidei, D., ...

Data taken by the Mark II detector at the PEP storage ring was used to measure the rate of dilepton production in multihadronic events produced by e+e- annihilation at [radical sign]s=29 GeV. We...

Measurements of Z-boson resonance parameters in e+e- annihilation (1989)

Abrams, G. S., Adolphsen, C. E., Averill, D., Ballam, J., Barish, B. C., Barklow, T., ...

We have measured the mass of the Z boson to be 91.14±0.12 GeV/c^2, and its width to be 2.42-0.35+0.45 GeV. If we constrain the visible width to its standard-model value, we find the partial width to...

First measurements of hadronic decays of the Z boson (1989)

Abrams, G. S., Adolphsen, C. E., Aleksan, R., Alexander, J. P., Averill, D., Ballam, J., ...

We have observed hadronic final states produced in the decays of Z bosons. In order to study the parton structure of these events, we compare the distributions in sphericity, thurst, aplanarity, and...

Search for B-decay to Higgs bosons for Higgs boson masses between 50 and 210 MeV/c2 (1989)

Snyder, A., Murray, W. N., Abrams, G., Adolphsen, C. E., Akerlof, Carl W., Alexander, J. P., ...

We use data from the Mark II experiment at PEP to search for the process B-->h0X for mh0 between 50 and 210 MeV/c2. No evidence for the Higgs boson is seen in this mass range. The limit obtained...

Studies of jet production rates in e + e − annihilation at E cm =29 GeV (1989)

Schwarz, A. S., White, S. L., Koska, Wayne A., Fordham, C., Schmidke, W. B., Field, R. C., ...

Production rates of multijet hadronic final states are studied in e + e − annihilation at 29 GeV center of mass energy. QCD shower model calculations with exact first order matrix element weighting...

The Mark II detector for the SLC (1989)

Abrams, G., Adolphsen, C. E., Akerlof, Carl W., Alexander, J. P., Alvarez, M., Averill, Damon R., ...

The Mark II detector has been upgraded in preparation for its role as the first detector to take data at the Stanford Linear Collider. The new detector components include the central drift chamber,...

Initial measurements of Z-boson resonance parameters in e+e- annihilation (1989)

Abrams, G. S., Adolphsen, C. E., Aleksan, R., Alexander, J. P., Allen, M. A., Atwood, W. B., ...

We have measured the mass of the Z boson to be 91.11±0.23 GeV/c^2, and its width to be 1.61-0.43+0.60 GeV. If we constrain the visible width to its standard-model value, we find the partial width to...
