Non-evaporable getters (NEG) are widely used in ultra-high vacuum (UHV) systems to improve vacuum quality by adsorbing gas molecules like hydrogen and carbon monoxide, which are commonly present in such systems. To function as a vacuum pump, NEG requires activation through specific processes. Traditionally, activation has been achieved by heating the NEG to high temperatures over extended...
A tuner based on Low loss ferroelectric material exhibits extraordinary performance in the application of suppressing microphonics in SRF cavities. For many applications, this could reduce significantly RF power consumption of accelerators. With this presentation, we will demonstrate Euclid’s fast ferroelectric tuning technology in RF power configurations that combine the RF power source...
Structure Wakefield Acceleration (SWFA) is a leading candidate among advanced acceleration concepts (AACs), offering a promising solution to overcome the limitations of traditional radiofrequency (RF) accelerators. By utilizing ultra-short microwave pulses (~10 ns) to drive advanced accelerating structures, SWFA aims to significantly increase accelerating gradients and enhance energy...
As a part of research into the fabrication methods for superconducting radio frequency (SRF) cavities used in International Linear Collider (ILC), we have fabricated two 1.3 GHz single-cell cavities using niobium materials with different grain sizes; fine grain (ASTM 5-6) and medium grain (ASTM 0-3). Both cavities has been fabricated using identical manufacturing equipment to ensure process...
The data acquisition system is newly developed for more precise signal measurements in KOMAC 100 MeV linac. Beam and RF signals measured by the diagnostic equipment may be collected using various devices. While oscilloscopes are capable of precise signal analysis, it is difficult to collect synchronization data with other devices while operating large accelerators. The data acquisition system...
The low energy part of the superconducting linac has been developed in the first phase of RISP (rare-isotope science project). The installation of the linac was completed in 2021. The linac consists of two different types of superconducting cavities, QWR (quarter wave resonator) and HWR (half wave resonator). The QWR cryomodule has a single cavity. There are 2 different types of cryomodules in...
In 2015 and 2018, the Dongnam Institute of Radiological & Medical Sciences (DIRAMS) in Busan, Korea, developed 6-MeV and 9-MeV C-band electron linear accelerators (LINACs) for radiation therapy research. The DIRAMS is working on developing the domestic radiation therapy devices through the development of core parts of LINAC by establishing an precision processing system and a vacuum brazing...
