Description
The diffusion of electrons from ECRIS plasmas results
in the emission of bremsstrahlung distributions from
the plasma chamber. ECRIS bremsstrahlung
measurements that are both time- and energyresolved
are often challenging to perform due to the
10's; 100's ms timescale that the plasma evolves
over. However, the advancement of low-cost
microcontrollers over the last decade makes timing
and gating photon spectrometers easier. We present
a proof of principle measurement which uses an
Arduino microcontroller as a gate-and-delay
generator for a High Purity Germanium (HPGe)
detector. An example plot of the time-resolved
bremsstrahlung spectrum, triggered by beam current
variation induced by kinetic instabilities, is shown.
