Abstract:
The New Small Wheel (NSW) is an upgrade for the ATLAS detector to provide enhanced
triggering and reconstruction of muons in the forward region. The large LV power demands
of the NSW necessitate a point-of-load architecture with on-detector power conversion. The radiation
load and magnetic field of this environment, while significant, are nevertheless still in the
range where commercial-off-the-shelf power devices may suffice.
We present studies on the radiation-hardness and magnetic-field tolerance of several candidate
buck converters and linear regulators. Device survival and performance are characterized when
exposed to gamma radiation, neutrons, protons and magnetic fields.
