1. A THICK TARGET FOR SYNCHROTRONS AND Betatrons.United States: N

2. Design and development of printed circuit boards with the exclusion of particle accelerators and synchrotrons

3. Energetic helium nuclei may be produced by cyclotrons, synchrotrons, and other particle accelerators, but they are not normally referred to as "alpha particles."

4. So, in a sense, the largest and most powerful “microscopes” are the particle accelerators —cyclotrons, synchrotrons, and others— the size of some being measured in miles.
