Radiopurity measurements of liquid scintillator for the COSINE-100 Upgrade
J. Kim, C. Ha, S. H. Kim +12
A new 2,400 L liquid scintillator has been produced for the COSINE-100 Upgrade, which is under construction at Yemilab for the next COSINE dark matter experiment phase. The linear-…
Microwave power and chamber pressure studies for single-crystalline diamond film growth using microwave plasma CVD
Truong Thi Hien, Jaesung Park, Cuong Manh Nguyen +2
Single-crystalline diamond (SCD) films possess exceptional thermal, chemical, and optical properties, making them ideal for advanced applications. However, achieving uniform film q…
A Two-Week Monitoring Campaign on Mrk 421
