The International linear collider (ILC) is a very complicated and expensive project. One aspect of key importance is the main beam dumps, which are required to safely dispose of the high power ILC beams. The work on such dumps was started at the SLC, albeit at much lower power, and continued as part of the TESLA project. However, much more work is needed to(More)
It is well known that millimetre-wave systems can penetrate poor weather, dust and smoke far better than infrared or visible systems. Imaging in this band offers the opportunity to be able to navigate and perform surveillance in these conditions of poor visibility. Furthermore, the ability to penetrate dielectrics such as plastic and cloth has opened up the(More)
We revisit the impact of the jet algorithm on predictions of energy flow into gaps between hard jets, defined using the kt clustering procedure. The resulting prediction has two distinct components: a primary emission piece that is related to independent emission of soft gluons by the hard jets and a correlated emission (non-global) piece known only in the(More)
Gas exchange measurements made with single leaves from Wych elm (Ulmus glabra Huds.), Lombardy poplar (Populus nigra ‘Italica’ L.) and common oak (Quercus robur L.) seedlings grown at high irradiance showed significant interspecific differences in the stomatal response to variation in atmospheric humidity. Elm and poplar seedlings showed low conductances at(More)
The ultracold plasma-based electron source has recently been proposed as an alternative to conventional photoinjectors or thermionic electron guns, which are widely used in today’s particle accelerators. The advantages of the ultracold plasma-based electron source lie in the fact that the electrons extracted from the cold plasma (from near threshold(More)
The problem of obtaining Raman spectra at high pressures with a diamond anvil cell is analyzed, and the successful use of a 90 degrees off-axis ellipsoidal mirror for collection in both 0 degrees and 180 degrees scattering modes is demonstrated with nu(OH) spectra of ice VI, VII, and vIII.
