In the field of nuclear medicine, there has been a growing demand for devices that can image gamma rays of several hundred keV. For example, radioactive gold nanoparticles have been proposed as ideal drug carriers that can be traced using their 412-keV gamma rays. However, devices offering high spatial resolution for imaging using such high-energy gamma rays have not yet been developed....
Positron emission tomography (PET) systems greatly benefit from precise timing measurements, especially in time-of-flight (TOF) applications, which enhance image quality by providing more accurate localization of positron annihilation events. Current commercial TOF systems typically require Time-to-Digital Converters (TDCs) with timing resolutions in the range of 10-20 picoseconds (ps) to...
General Fusion is developing a prototype fusion machine under its Lawson Machine 2026 (LM26) program, leveraging the principles of magnetized target fusion. A key objective of LM26 is achieving an ion temperature of ≥10 keV, which presents significant challenges in accurate temperature measurement. To address this, a time-of-flight neutron spectrometer is proposed.
In deuterium-deuterium...
