THE MATERIAL FLOW ON AGRICULTURAL FARMS

Prestože význam logistiky v prumyslu, obchodu a dalších oborech je všeobecne uznáván, v zemedelství není tato problematika systematicky zkoumána. Predpokladem podrobných analýz je znalost objemu a struktury materiálového toku. Autori k tomuto úcelu navrhli vlastní metodiku, která vychází z technologických ukazatelu, publikovaných Ministerstvem zemedelství CR pro jednotlivé plodiny a kategorie zvírat. Tyto publikované normativní hodnoty Ministerstva pak slouží jako základní kameny, jejichž kombinací lze zjistit objem materiálového toku a jeho strukturu v podniku behem jednoho roku. Výhodou metodiky je rychlé zjištení potrebných dat a možnost zohlednení nekterých specifických podmínek ve zkoumaných podnicích.In spite that the great importance of logistics in industry, business and other branches is generally acknowledged, this problem is not systematically investigated in agriculture. As a presumption of detailed analysis, the knowledge of the volume and structure of the material flow is necessary. The authors have proposed their own methodical procedure which issues from technological indicators, published by the Czech Ministry of Agriculture for individual plants and categories of animals and which makes possible further classification of these data for enterprises with different level of farming. These published standards of the Ministry serve as basic stones and by means of their combination, the volume of material flow and its structure is possible to calculate during one year\u27s periods. The advantage of proposed method is a fast finding out of necessary data and possibility of taking into account some specific conditions in investigated enterprises

RK-TBA studies at the RTA test facility

Construction of a prototype RF power source based on the RK-TBA concept, called the RTA, has commenced at the Lawrence Berkeley National Laboratory. This prototype will be used to study physics, engineering, and costing issues involved in the application of the RK-TBA concept to linear colliders. The status of the prototype is presented, specifically the 1-MV, 1.2-kA induction electron gun and the pulsed power system that are in assembly. The RTA program theoretical effort, in addition to supporting the development of the prototype, has been studying optimization parameters for the application of the RK-TBA concept to higher-energy linear colliders. An overview of this work is presented. 1 fig

Stacked insulator induction accelerator gaps

Stacked insulators, with alternating layers of insulating material and conducting film, have been shown to support high surface electrical field stresses. We have investigated the application of the stacked insulator technology to the design of induction accelerator modules for the Relativistic-Klystron Two-Beam Accelerator program. The rf properties of the accelerating gaps using stacked insulators, particularly the impedance at frequencies above the beam pipe cutoff frequency, are investigated. Low impedance is critical for Relativistic-Klystron Two-Beam Accelerator applications where a high current, bunched beam is trsnsported through many accelerating gaps. An induction accelerator module designs using a stacked insulator is presented

High current heavy ion beam transport experiment at LBL

Information on the current limit in a long quadrupole transport channel is required in designing an accelerator driver for an inertial confinement fusion system. Although a current transport limit was proposed by Maschke, quantitative estimates require a detailed knowledge of the stability of the beam. Analytic calculations based on the Kapchinskij-Vladimirskij (K-V) distribution function have identified transversely unstable modes, but particle simulations have shown that some of the K-V instabilities are benign, i.e., particles redistribute themselves in the 4-D transverse phase space, but the rms emittances do not grow. Some preliminary results of beam transport experiments were reported in the 1983 Particle Accelerator Conference in Santa Fe
