Query: Inter-ELM pedestal evolution on MAST and impact of Resonant Magnetic
  Perturbations   The peak pressure gradient in the pedestal (dPe/d{\psi}) on MAST varies
little between edge localized modes (ELMs), although it varies between
discharges due factors such as gas fuelling and plasma current. The pressure
pedestal width in flux space on the high-field side (HFS), both during the
inter-ELM period and amongst different plasma discharges is consistent with a
scaling of . In flux space very similar dPe/d{\psi} and {\Delta}pe are observed
on the HFS and low-field side (LFS) in single null configuration. This symmetry
is broken by the application of resonant magnetic perturbations (RMPs). During
ELM mitigation by application of RMPs changes in the edge transport barrier
position and width are observed. These changes are dependent on the intensity
of the RMP and on the toroidal location with respect to the RMP phase. An
outward displacement of up to 30 mm and increase in the edge pedestal width of
up to 50% with respect to the coils case off are observed. Increased particle
transport causes a decrease in ne,ped, and hence Pe,ped, as is observed on
other devices. The combination of an increase in {\Delta}pe on the LFS and
decrease in Pe,ped results in significantly reduced LFS dPe/d{\psi} when these
perturbations are applied to the plasma edge. A decrease in dPe/d{\psi} on the
HFS is also observed due to RMP; however, this decrease is caused solely by the
Pe,ped decrease whilst no expansion of {\Delta}pe on the HFS is observed.
