Wang, X., Boreiko, A., Schloßmacher, U., Brandt, D., Schröder, H.C., Li, J., ...
The glass sponge Monorhaphis chuni (Porifera: Hexactinellida) forms the largest bio-silica structures on Earth; their giant basal spicules reach sizes of up to 3 m and diameters of 8.5 mm....
High-temperature LPP collector mirror (2006)
Feigl, T., Yulin, S., Benoit, N., Kaiser, N., Böwering, N., Ershov, A., ...
The EUV source output power and the collector optics lifetime have been identified as critical key issues for EUV lithography. In order to meet these requirements a heated collector concept was...
Selenium affects biosilica formation in the demosponge Suberites domuncula (2005)
Mueller, W.E.G., Borejko, A., Brandt, D., Osinga, R., Ushijima, H., Hamer, B., ...
Selenium is a trace element found in freshwater and the marine environment. We show that it plays a major role in spicule formation in the demosponge Suberites domuncula. If added to primmorphs, an...
On trapped modes in the LHC recombination chambers: numerical and experimental results (2002)
Brandt, D, Caspers, Friedhelm, Li, D, Migliorati, M, Mostacci, A, Palumbo, L, ...

This paper presents an intermediate review of the single bunch collective effects in the LHC. It first reviews the LHC impedance budget including all elements for which a design is presently...
Review of the LHC Ion Programme (2000)
Since 1995, a non-negligible amount of boundary conditions have changed for the potential operation of the LHC as an ion collider. The aim of this paper is to review these modifications and evaluate...
Brandt, D, Caspers, Friedhelm, Mostacci, A, Rinolfi, Louis, Ruggiero, F, Tsutsui, H, ...
In order to better understand the RF shielding properties of a thin resistive layer inside a ceramic vacuum chamber, an experimental set-up has been installed in the Electron Positron Accumulator...

Is LEP beam-beam limited at its highest energy? (1999)
Brandt, D, Herr, Werner, Meddahi, Malika, Verdier, A
The operation of LEP at 45.6 GeV was limited by beam-beam effects and the vertical beam-beam parameter xy never exceeded 0.045. At the highest energy of 94.5 GeV, the increased damping allows higher...
Experience with a Low Emittance Optics in LEP (1999)
Brandt, D, Herr, Werner, Lamont, M, Meddahi, Malika, Verdier, A, Vos, L
Since start-up in 1998, LEP has operated with a low emittance lattice with a phase advance of 102 deg in the horizontal and 90 deg in the vertical planes. This optics provides a horizontal detuning...
LEP Performance Limits revisited (1998)
A first estimate of the LEP performance in 1999-2000 has been presented in Ref. [1]. Based on new data collected during the 1998 run, some of the basic parameters entering the calculation have been...
A Candidate Low Emittance Lattice for LEP at its Highest Energies (1998)
Brandt, D, Herr, Werner, Jowett, John M, Lamont, M, Meddahi, Malika, Verdier, A
Several low emittance lattices have been proposed for LEP at its highest energies in order to reduce the horizontal beam size and bring the beam-beam limit within reach. However, optics with high...
On LEP Performance Limits in 1999 and 2000 (1998)
Brandt, D, Hübner, K, Myers, S
A first estimate of the performance of LEP expected in 1999 (2000) is presented taking into account the configuration of LEP in this period when all the upgrades will have been implemented. Based on...
