We would like to thank S. Kim, J. Han, C. Kim, H. Kang, and Y. Kim (KAERI) for their technical help with regard to the instrumentation of TASs and development of film-coated collimators. We also wish to thank Dr. Y. Choi and Dr. S. Park (KAERI) for their initial design and construction of Thermal TAS and Cold TAS, respectively. We greatly appreciate the advice of Prof. Y. Noda (Tohoku University, Japan) on TAS instrumentation and the help of Dr. S. Yano (National Synchrotron Radiation Research Center, Taiwan) for the neutron transmission experiment on SIKA, which was conducted under the User Program of ANSTO Facilities: Proposal No. IC7569. The work at KAERI was conducted under the projects of "Neutron Basic Research on Scattering Instrument Optimization and Operation" (521210-18 and 521210-19) and "Optimization and Operation of Neutron Scattering Instrument for Quantum Materials Research" (524210-20).
