At KOMAC (Korea Multi-purpose Accelerator Complex), a 100-MeV proton linac has been started to operate since 2013. Nowadays, the constructions of the total six beamlines are completed. Among them, 20 MeV or 100 MeV proton beam has been provided to users through the three beamlines. The proton beam irradiation facilities could provide the proton beam and the available proton energy range is from 20 MeV to 100 MeV. The proton irradiation is performed in the air, therefore, the intensity and profile and position of provided proton beam should be measured in the air. For in-situ beam intensity and profile monitoring, in-air type ACCT, the large area transmission ionization chamber and multi-wire grid were adopted to the new experimental set-up for the proton beam irradiation test. As a reference dosimetry, the farmer-type ionization chamber and in-air type faraday-cup will be utilized for the fluence and dose measurement at the sample position. In this paper, we will introduce the operation status of the proton beam irradiation facility at KOMAC, the test results of in-air beam diagnostics tool and their lessons in these facilities will be given.
