- REMINDER FOR THE USE OF RF FINGERS:
    1) The RF fingers should be made of Au (or Ag) plated CuBe (grade C17410) and they should be in contact with a Rh plated material
.
    2) Au has been used for the PIMs (as it is better for the cold welding) and Ag for the collimators (as Au cannot be used because of the bake-out at ~ 250 deg C => Due to the diffusion of the Cu into Au and then the Au layer disappears). The same problem happens with Ag but at a higher temperature.
    3) In case of bake-out the grade of the CuBe is very important!
    4) SS (instead on Cu-Be, but still Au plated) is used for the MKI RF fingers because of the bake-out at ~ 350 deg C which would lead with Cu-Be to a very small residual elasticity of ~ 20% only (see slide 27 of SC's talk during 3rd meeting).



- REMINDERS FOR VACUUM CONVENTIONS:
    1) In VMXYZ, X describes the flange, Y describes the RF insert topology and Z describes the body (1 port, 2 ports etc.).
    2) Y = A for vacuum pipe diameter 80/80 (standard), Y = B for 63/63 (vacuum valves), Y = C for 63/80 (vacuum valves) and Y = O for 100/63 (vacuum valves).

    3) VA = Vacuum Assembly, VB = Vacuum Bellows, VC = Vacuum Chambers, VD = Vacuum Dump Lines, VE = Vacuum Bakeout, VF = Vacuum Flange, VG = Vacuum Gauge, VH = Vacuum Support & Handling, VI = Vacuum Instrumentation, VJ = Vacuum Seal, VM = Vacuum Modules, VN = Vacuum Cleaning, VP = Vacuum Pump, VS = Vacuum Screen, VT = Vacuum Tombac / Flexible Hoses, VV = Vacuum Valve, VW = Warm Beam Vacuum.
