Which airports in Ireland use Surface Movement Radar?
The wording of this IAA information implies that it's Dublin only:


  The IAA also operate an Advanced Surface Movement Guidance and Control
  System (ASMGCS), which facilitates the safe movement of aircraft and
  airport vehicles at Dublin Airport, even during poor visibility
  conditions. The ASMGCS incorporates Surface Movement Radar,
  Multilateration and ADS-B.


There's a similar comment in this document. And the AIP entry for Dublin mentions surface radar in the obstacles list, but the entries for Cork and Shannon (the next busiest airports) don't.
