Overview
Initial compensation tests on mini SFTPRO1 (MD2, MD_SFT_PRO_MTE_L4329_2024_V1) were cancelled as BPMs did not measure correct radial position at flat top (C4000-C7000)
Further tests were carried on flat bottom on MD3 (typical MD cycle, MD_26_L7200_Q20_North_Extraction_2024_V1), where the flattening corrections were carried out. Results can be found below. Results were overall successful, but the model tended to overcorrect, so we measured radial position on only the first trim with gain 0.5, which looks fine.
Measurement suggests that field measurements drift already on flat bottom, and while the field measurements seem to be ramping, the radial position stays more or less constant.
