Funding: This work was supported by the National Research Foundation of Korea(NRF) grant funded by the Korea government(MSIP) (no. NRF-2014M2C3A1029534). Since an aperture of a low energy beam transport line of the KHIMA is quite large, 100 mm, to minimize an uncontrolled beam loss, large aperture Faraday-cup with the diameter of 100 mm is installed to measure the beam current from the electron cyclotron resonance ion source (ECR-IS) and to identify the ion species using analyzing magnet. The suppression ring is designed to reduce the repelling electrons for an accurate measurement. The Faraday-cup has the cooling channel with the heat capability of 100 W to recover the heat from the ion beam for safety during the operation. In order to reduce the noise propagation from the cooling channel, the cooling channel is insulated with the cup. In this presentation, we show the physical modeling, mechanical aspect for design the large aperture Faraday-cup, and the result of in-beam test with the ECR-IS in KHIMA. |

Funding: RIKEN IPA scheme and Cockcroft Institute Core Grant Electron Cyclotron Resonance (ECR) ion sources supply a broad range of ions for post acceleration in cyclotrons. Here, an effort to improve the beam transfer from RIKEN's 18 GHz ECR ion source to the Low Energy Beam Transfer (LEBT) line and an optimization of the performance of the ion source is presented. Simulation studies have shown that less than 20% of the beam is currently transferred. The first goal is to measure the transverse beam emittance in real time. The emittance monitor designed and fabricated for this purpose utilizes a pepper pot plate followed by a transparent scintillator and a CMOS camera for image capture. The second goal is to find the optimal operating point of the ion source by sweeping parameters such as RF power, vacuum pressure, extraction electrode position and voltage. To this extent, modifications of the ion source took place, as well as a measurement of the magnetic field inside the ion source. In this contribution the results of the emittance and other operating parameters measurements, as well as the design details of the emittance monitor are presented |

| The rigorous process in place at CERN to approve and follow-up the implementation of any modification of the LHC machine and its Injectors is presented in this paper. Our methodology implies the support of three teams, in charge of the configuration management, the scheduling and safety coordination, and the 3D integration studies. At each stage of the project the support of the three teams evolves, to provide the adequate support in the preparation phase and during the technical stops and long shutdowns. The formal roles and the processes used to govern the interaction of the Integration, Configuration and Coordination teams, and their relation to the project teams during the preparation and implementation phases, for activities to be performed in LHC and its injector chain are described and discussed. | |||
