First results from the Bryn Mawr Magnetohydrodynamic Experiment (BMX) at the Bryn Mawr Plasma Laboratory.

The first measurements from the Bryn Mawr Magnetohydrodynamic Experiment (BMX) are presented. BMX is a magnetic turbulence experiment at the Bryn Mawr Plasma Laboratory (BMPL) consisting of an ~300us long coaxial plasma gun discharge that injects magnetic helicity into a 24cm by 2m flux-conserving chamber in a process akin to sustained slow-formation of spheromaks. Broadband temporal fluctuation measurements using a low-inductance magnetic pickup coil and fast Langmuir probe are reported. Mapping of gas flow using a fast ionization gauge as well as measurements of the plasma gun magnetic field structure are also reported
