Presently, there is no information available about the effect of bunch compactness and berry thinning methods on wine grape quality sensory attributes in ‘Monastrell’ cultivar. Thus, main aim present study was to determine influence two methods, which consisted reduction 25% 50% number berries each bunch, organoleptic this Non-compact bunches both showed a significant total yield, compactness, ...

Plasma Wake-Field Acceleration (PWFA) has demonstrated acceleration gradients above 50 GeV/m. Simulations have shown drive/witness bunch configurations that yield small energy spreads in the accelerated witness bunch and high energy transfer efficiency from the drive bunch to the witness bunch, ranging from 30% for a Gaussian drive bunch to 95% for bunch with triangular shaped longitudinal prof...

In the framework of the CLIC (Compact Linear Collider) RF power source studies, the scheme of electron pulse compression and bunch frequency multiplication, using injection by RF deflectors into an isochronous ring, will be tested, at low charge, during the preliminary phase of the new CLIC Test Facility (CTF3) at CERN. In this paper, we describe the beam dynamics studies made in order to asses...

Large transverse wake fields can be generated via the interaction between a relativistic electron or positron bunch and a plasma, and the bunch will therefore be self-pinched. In this paper we derive a new and general formulation for the plasma wake field in a compact expression. We then suggest that this self-focusing effect can be used as a mechanism to enhance the luminosity for high energy ...

Plasma photocathode wakefield acceleration combines energy gains of tens of GeV m-1 with generation of ultralow emittance electron bunches, and opens a path towards 5D-brightness orders of magnitude larger than state-of-the-art. This holds great promise for compact accelerator building blocks and advanced light sources. However, an intrinsic by-product of the enormous electric field gradients i...

With the growing demand for FEL light sources, cost issues are being reevaluated. To make the machines more compact, higher frequency room temperature linacs are being considered, specifically ones using C-band (5.7 GHz) rf technology, for which 40 MV/m gradients are achievable. In this paper, we show that an X-band (11.4 GHz) linac using the technology developed for NLC/GLC can provide an even...

Quantum radiations sources such as a laser Compton scattering (LCS) X-ray and coherent THz radiation sources have been developed on the basis of the S-band compact electron linac at AIST in Japan. The compact Xray source is required for biological, medical and industrial science because it has many benefits such as short pulse, quasi-monochromatic, energy tunability and good directivity. The X-...

During the beam test of a tracker prototype for the Compact Muon Solenoid detector proposed for the LHC, the time response of the Microstrip Gas Chambers was studied using diierent gases and chamber gaps. The subsequent eeciency to identify the bunch crossings at LHC is discussed for several algorithms used in the oo-line signal processing of the data.

comparison and grouping of 32 grape cultivars and genotypes by using 61 traits including; 5 phenological and vegetative characters, 41 traits related to fruit and amount of resveratrol in 15 parts of plant was done according to grape descriptor and related methods. according to the results some traits such as spikelet weight, berry color, length of peduncle, length of berry tail, weight and len...
