• Moskov, Hovanes, and Edy were present at the BTeam meeting on November 12th to discuss the possibilities of beam tests during 2025 running.

• The estimated time for setting up the laser for KLF, conducting the tests, removing KLF laser, and replacing GlueX laser was about 3 to 4 calendar days.

• Physics division representative (Doug) did not think that the benefits from these beam tests would justify spending that much beam test time considering that there are other beam tests that would need to happen.

• There should not be any problem to do the tests requiring beam only in the injector. They could be done right after the spring 2025 is competed but before SAD starts. These tests would give us some idea on the amount of bleedthrough beam between the main bunches and possibly on the impact of KLF beam on Moller (one of the Riad's tests).

• Doug stated during that meeting it is possible that the only way to check compatibility of MOLLER and KLF is after the whole MOLLER instrumentation is installed, that is earliest time is 2027. It was not also certain when MOLLER installation will be complete. This would jeopardize the installation scheduling of KLF experiment this summer or fall, according to Hovanes.
