The Iron flew to Dublin on Monday morning for the camp, which includes games against Bray Wanderers and Wayside Celtic.
They take on Bray on Tuesday night and Wayside on Thursday, with both matches kicking-off at 7.45pm.
The Iron, who will be based at the four-star Carton House hotel, have not revealed the names of the trialists.
One of the first acts after arriving on Monday was to hand over a signed shirt, which will sit in the hotel's reception alongside another team who spent a pre-season there - the Spanish giants Real Madrid.
