HOM Survey on 2L05 has been completed in our lunch time. Only first HOM passband TE111 modes were able to be measured and data fitted in parallel. Two high-Q modes, one at Cavity 2 another at Cavity 7 predicted by Poltif in ~10^7 have been manually measured and confirmed to be lower at ~10^5 because they are sitting on the noise grass level. No other high-Q mods have been found on all other cavities. Due to the NL is under the high-power commissioning except this 2L05 cryomodule. There are too much noise picked up on the second and third HOM passband TM110 and TE112 modes.
