I dont know about the Deacon, but I know he is unable to turn his back on the Tabernacle(assuming it is located in the center). It does however need to be clarified that this only means that if i draw a line straight through the priest, it shouldn’t also go through the tabernacle. The rubrics are set up so that the Priest is always to the side of the Tabernacle when he turns around.
