A particle in cell code has been developed to simulate the steady state of electron plasmas in an electron beam Penningtrap and to study its scaling law.

To detect such a tiny force, the NIST team confined about 60 ultra-cold beryllium ions in a device called a Penningtrap, which USES magnetic and electric fields to imprison charged particles.
