Update specifications for the IR3 layouts (P. Hermes)

PH showed an updated version of the IR3 functional specification document following internal discussions with the CERN groups involved, when it was decided (EDMS 2811718) that the construction of two new goniometers compatible with high intensity is not feasible for beam tests before the end of Run 3. For the TCCS will use the design of the IR7 TCPC (featuring a replacement chamber) and in fact plan to recuperate one device from the pool of those removed from IR7, with a new crystal produced for TWOCRYST. The new version of the specs will be circulated soon.

Review of goniometer impedance considerations (C. Antuono)

CA reviewed the present status of impedance calculations for TCCS and TCCP and discussed some suggestions for improvements. See details in the slides.
