The resistive wall impedance of cylindrical vacuum chambers was first calculated over 40 years ago. The original results were valid for metal vacuum chamber walls which are thick compared to the skin depth at the frequencies of interest. Recently the

A new physical regime is revealed by the LHC collimators. Small aperture paired with large wall thickness ask for a different physical picture of the resistive wall effect than the classical one. Two general formulae for multi-layer resistive-wall im

We start with previous results [1] for the longitudinal impedance of a wire cage withing a cylindrical pipe and generalise the outer boundary condition to include the case of a conducting pipe and of a ferrite pipe. The results are then interpreted b

We present an analysis of shielding of electromagnetic fields excited by beams of charged particles surrounded by thin conducting layers or metal stripes inside an external structure of finite length. The ability of shielding by a layer thinner than

The reciprocity theorem is used to prove the symmetry of the longitudinal impedance of an accelerating structure with respect to exchange of the coordinates of the leading and trailing particles. (2 refs).

We calculate the transverse resistive wall impedance of the LHC beam screen, consisting of a tube of stainless steel with a thin inside layer of copper. For this we use an algorithm for the calculation of the electromagnetic fields of an oscillating

USING AN ALGORITHM FOR THE CALCULATION OF ELECTRO-MAGNETIC FIELDS OF OSCILLATING CIRCULAR CYLINDRICAL BEAMS SURROUNDED BY ANY NUMBER OF ANNULAR LAYERS OF ARBITRARY MATERIAL PROPERTIES, WE CALCULATE THE TRANSVERSE RESISTIVE WALL IMPEDANCE OF THE BEAM

In many hig-energy storage rings the beam chamber is connected to a separate pump chamber by a metallic wall with many holes or slots whic permits passage of the rest gas. In LEP, the pump chamber contains a metallic 'negstrip' pump, and thereby beco

Collective effects due to the impedance of structures along the vacuum chamber can limit the performance of accelerators and storage rings. In particular in LEP, transverse impedances are limiting single bunch currents in the vertical, but - to a som
