We have estimate that a significant contribution to the Micro-Channel Plate Photo-Multiplier Tube (MCP-PMT) response as part of the shower maximum detector (SM) originates from the secondary emission of the MCP. We present test beam results, obtained directly with MCP as part of the SM without photoelectrons produced in MCP-PMT input window. This is performed with a Photonis XP85012 MCP-PMT, which allows photocathode to be turned off. The SM time resolution at the level of 30 ps is obtained.
