  • Superconducting RF cavities are being considered for accelerating a proton beam at 700 MHz in the linac of the Proton Engineering Frontier Project (PEFP) and its post-project. Dumbbell fabrication is a mid-process for manufacturing an elliptical superconducting RF cavity. During the dumbbell fabrication, control of the dumbbell length and the $TM010\;{\pi}$ mode frequencies is necessary to build up a desired cavity. A new formula with a perturbation measurement method is used to measure and calculate the frequencies of the individual half-cells of a PEFP low-beta dumbbell, and to tune the frequency and length of the half-cells. In this article, the tuning method and results of the PEFP low-beta dumbbells have been presented.

  • The PEFP (Proton Engineering Frontier Project) is constructing a 100MeV proton Linac (Linear Accelerator). The 20 MeV 20 mA proton beam has been serviced for an application in the fields of material, biological, information technology and medical sciences. For a stable and efficient acceleration of a proton beam, the control requirements must be optimized by studying various control methods. We propose that the integrated control system for the Linac machine components must be based on a distribution control method to improve a centralized control system. Based on EPICS (Experimental Physics and Industrial Control System) real-time software, the VME (Versa Module European package format) IOC (Input Output Controller) was developed under cross development environment with a RISC (Reduced Instruction Set Computer) PowerPC system. In this paper, we describe the design and implementation of distributed control system using the VME-based EPICS middleware for various components of the large proton accelerator.

  • 한국 원자력 연구소는 PEFP(Proton Enginnering Frontier Poject)라고 하는 프로젝트를 수행 중이며, PEFP는 고에너지 양성자 가속기에 대한 프로젝트이다. 양성자 가속기에 대한 제어 시스템은 안정적인 운전 제어를 위해서 장치의 상태를 주기적으로 모니터링 할 뿐만 아니라 장치상태를 저장하여 일정시간 후에 확인이 요구되면 저장된 데이터를 이용하여 이전 정보를 추적할 수 있어야한다. 따라서 양성자 가속기 제어시스템에서는 실시간으로 들어오는 진공 데이터 정보를 저장 및 저장된 데이터를 열람이 가능한 저장 시스템으로 구성하였다. 저장된 데이터들은 RFQ(Radio Frequency Quadrupole) Cryopump, Turbo Pump, Press Gauge, Gate Valve, Compressor와 DTL(Drift Tube Linac) Multi-Gauge, Turbo Pump등의 진공도 및 제어변수 등이 있다. 이들 각각의 진공장치로부터 전달되는 진공 데이터들을 저장하기 위해 EPICS Extension toolset중에서 저장하는 기능을 가진 Channel Archiver를 양성자 가속기 제어 시스템에 추가하였다
