CERN LHC Project Note 63 (1996)
Coherent Losses in the CMS Experimental Chamber

August 1996
Abstract:
In a previous note, we calculated the single bunch loss factor
associated with the CMS experimental chamber in the LHC.
The aim of this note is to extend the
analysis to the coherent losses in the CMS experimental chamber.
Because of the large number of bunches in the LHC, the coherent loss factor
can reach rather large values and a careful analysis of the
bunch frequency spectrum and the frequency spectrum of the trapped modes in
the CMS experimental chamber is necessary. The analysis shows that
an additional RF-screen can reduce the coherent losses to values as
low as 40 W.
