Sector Pair Overview |
Notes:This diagram shows an overview of a given sector pair in the linac, consisting of an odd sector followed by an even sector, in the sense that the "downstream" or eastward direction is to the right. This layout has been chosen because two of the important electrical components of the linac RF system serve two sectors: a VVS located in each even sector serves that sector and the odd sector preceding it; and an EMHP power supply for the klystron focusing solenoidslocated in each odd sector supplies all klystrons in that sector and the subsequent even sector. Note that this configuration is opposite to what is considered a "sector pair" in the PPS system, which divides the linac into pairs of sectors consisting of an even sector followed by an odd sector. This diagram may looks complicated at first, but once understood, it is in fact the simplest of the diagrams in this site. It illustrates five basic points:
