A Machine Access System (MAS) and a Personnel Access System (PAS) are being installed n the basement of Front End Building.

Similar equipment (PAS) will be installed in the HEBT Loading Bay area (level 090) and in the Target, as well as in the experiment halls. For the commissioning of the Normal Conducting Linac, the Temporary Shielding Wall being built will be used for radiation protection/access.
