A compact electron cyclotron resonance plasma source has been built and is being investigated in view of ion and x-ray production. A method recently developed to deduce the energetic electron temperature parameter from the bremsstrahlung spectra emitted by the plasma is adapted to the present plasma case and shows that this temperature parameter can reach a dozen keV. We show that the high-energy electrons are localized on a ring in the mirror midplane by obtaining the image of the x-ray emitters on the chamber walls with a pinhole camera. It indeed appears that the emitters are two rings, due to the hot electrons leaking towards the magnets from the midplane ring where they are located inside the plasma.
The COVID-19 crisis has forced Nuclear Medicine and Molecular Imaging Departments to cancel appointments, change procedures and protocols and adapt to significant changes rapidly. Nuclear Medicine Technologists are often on the frontlines, working and communicating directly with their patients. To provide advice and guidance to the community, eight nuclear medicine technologists from around the country were interviewed -a summary of their responses are documented below.
What protocols are Nuclear Medicine Technologists following regarding staffing the department during this crisis?Nuclear Medicine procedures have decreased exponentially during the COVID-19 crisis. Departments across the country are taking active measures to ensure the health and safety of their patients and nuclear medicine professionals working in the department. Staffing protocols and schedules are being revised to fit the needs and safety requirements of departments. Currently, in many institutions patients and staff are being screened upon entry into the department. If a patient is deemed a
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
