The development of the beam position monitor (BPM) is in progress for the 100-MeV proton linac and 10 beam lines of the 1st phase of KOMAC. Those were selected the strip line type BPM for the proton linac and beam lines. 5 beam-line BPMs and 9 linac BPMs were checked their electrical performance in the RF test using by developed test stand and tested the Log-ratio BPM (Beam Position Monitor) electronics module of the Bergoz Instrumentation for direct beam position derivation signal from the pickup signal. After then, those will be installed 100-MeV proton Linac and beam lines for beam commissioning in February 2013. This presentation summarized the results of measured BPM’s electrical performance and the Log-ratio BPM electronics pickup sensitivity.

  A 100-MeV proton linac has been developed as the 1st phase of KOMAC (Korea Multi-purpose Accelerator Complex) under the project name of PEFP (Proton Engineering Frontier Project). The accelerator operation has to be carried out with the objective of limiting beam losses to less than 1 W/m. When the un-intended excessive beam loss occur, the BLM(Beam Loss Monitor) inform this beam loss to operator and transmit the signal to the MPS (Machine Protection System) for the rapid shut-off of the machine. The scintillation detector and proportional counter were selected as the BLM detector because of their fast response time and high sensitivity. At the beam commissioning stage, 20 BLMs will be prepared for the beam loss monitoring. This paper will report preliminary operation results of beam loss monitoring system.

The development of the Korea Multi-purpose Accelerator Complex (KOMAC) accelerator facility was finished and went into the operation period from 2013. The facility consists of an 100-MeV proton linac including a 50-keV ion source, a 3-MeV RFQ, and a 100-MeV DTL, and 20-MeV and 100-MeV beam lines. The linac and beam lines were developed by the Proton Engineering Frontier Project (PEFP), the first phase of KOMAC from 2002 to 2012. The goal of the beam commissioning is delivering 100-MeV 1-kW proton beams to a beam bump in a 100-MeV target room. After finishing the commissioning, the user beam service will start from spring 2013. The KOMAC user facility consists of 2 beam lines in the initial operation stage and it will be increased to 10 beam lines in future. The one beam line is for 20-MeV proton beams which are extracted after 20-MeV part of the DTL tanks. A medium energy beam transport (MEBT) is installed there for the 20-MeV beam extraction and the beam matching to the next DTL tank. The other beam line is for 100-MeV proton beams. This work summarized the status of the KOMAC accelerator and beam lines.

Beamlines and 100-MeV proton linac have been developed for 1st phase of KOMAC(Korea Multi-purpose Accelerator Complex) at the Gyeong-ju site. The linac supply either 20-MeV or 100-MeV proton beams for beam applications. Each proton beam can be transported to 2 beamlines for industrial purpose and 3 beamlines for various researches. At the first phase, 2 beamlines were installed and under test. A detailed description of the installation and the preliminary test results will be presented in this paper.

The proton engineering frontier project (PEFP), which is the first phase of Korea multi-purpose accelerator complex (KOMAC), developed a 100-MeV proton linac which consists of a 50 keV injector, a 3-MeV radio frequency quadrupole (RFQ) and a 100-MeV drift tube linac (DTL). The installation of the linac was finished in 2012. The goal of the beam commissioning in spring 2013 is accelerating 100-MeV proton beams with the beam power of 1 kW to the beam dump which is located downstream of the linac. This work summarized the beam commissioning result for the linac.
