چکیده
FAIR BOOSTER OPERATION U Beam Intensity In the frame of machine experiments, the maximum accelerated number of U-ions (FAIR reference ion) could be increased to 7x10 ions per cycle. In parallel, the relative amount of beam loss during the cycle has been reduced to about 30% of the injected ions (figure 1). Essentially, this progress has been enabled by a careful machine setting with an optimized vertical closed orbit correction in each lattice cell. Thereby scraping of beam tails at aperture limitations has been minimized and the amount of desorbed gas and correspondingly the ionization loss reduced.

Acceleration of U-beams in the SIS18
Introduction To prepare the acceleration of highest intensities of intermediate charge state heavy ion beams for the FAIR project, several technical projects have been summarized in the SIS18 upgrade program. The various technical measures of this program are continuously accompanied and verified by machine experiments. Major goal is the reduction of ionization beam loss. The strong dependence ...
متن کاملThe Finite Horizon Economic Lot Scheduling in Flexible Flow Lines
This paper addresses the common cycle multi-product lot-scheduling problem in flexible flow lines (FFL) where the product demands are deterministic and constant over a finite planning horizon. Objective is minimizing the sum of setup costs, work-in-process and final products inventory holding costs per time unite while satisfying the demands without backlogging. This problem consists of a combi...
متن کاملIonization Beam Loss and Collimation in SIS18
Introduction Ionization of beam ions, especially at operation with intermediate charge states, combined with a strongly dynamic residual gas pressure may create major beam loss. The first experimental evidence has been obtained in SIS18 machine experiments in 2001 with U-ion beams. Operation with intermediate charge states is in general required to minimize the incoherent space charge tune shif...
متن کاملDevelopment of an Ensemble Multi-stage Machine for Prediction of Breast Cancer Survivability
Prediction of cancer survivability using machine learning techniques has become a popular approach in recent years. In this regard, an important issue is that preparation of some features may need conducting difficult and costly experiments while these features have less significant impacts on the final decision and can be ignored from the feature set. Therefore, developing a machine for p...
متن کاملNonlinear effects induced by closed orbit deformation in SIS18
For the SIS18 operations as booster for the SIS100 it is necessary to maximize its intensity and minimize the beam loss at nonlinear resonances. The understanding of the beam loss mechanisms needs a full experimental and theoretical beam dynamics study in order to quantify each source of the nonlinear errors in the machine. First results of a novel technique to identified the strength and locat...
