1. FBCT/ DCCT :

      • DCCT best resolution = 500nA and spill current is ~1uA. Resolution is not good enough. -> No

      • FBCT bandwidth insufficient (even with special beam dedicated to calibration). See Marek’s presentation at BIFT confirmed during the presentation at BIFT that it would not work. 4th BIFT - BCT for TT20 (3 July 2023) · Indico (cern.ch)

    2. CCC :

      • A CCC will be installed in TT20 after LS3 (Jocelyn). But that won’t be useful for calibrating the BSIs since it is before the splitting and the losses are unknown.

    3. Calibration sheet:

      • Need to sectorize the vacuum and have an airspace to insert a calibration sheet. Not discussed yet with physicists / integration / vacuum
