  Recently, we reported an ion trap experiment with an integrated
time-of-flight mass spectrometer (TOFMS) [Phys. Rev. Appl. 2, 034013 (2014)]
focussing on the improvement of mass resolution and detection limit due to
sample preparation at millikelvin temperatures. The system utilizes a
radio-frequency (RF) ion trap with asymmetric drive for storing and
manipulating laser-cooled ions and features radial extraction into a compact
$275$ mm long TOF drift tube. The mass resolution exceeds $m / \Delta m = 500$,
which provides isotopic resolution over the whole mass range of interest in
current experiments and constitutes an improvement of almost an order of
magnitude over other implementations. In this manuscript, we discuss the
experimental implementation in detail, which is comprised of newly developed
drive electronics for generating the required voltages to operate RF trap and
TOFMS, as well as control electronics for regulating RF outputs and
synchronizing the TOFMS extraction.
