Present MFT planes layout
Present MFT planes layout. Reduction of MFT detector planes inner diameter could produce ineterference with the bellows and the beampipe support during the installation phase. 16.5mm. 100mm. 16.5mm ( vertical movement toto be done in less the 40mm-space between two bellow ).
