6 Delayline Detector Layout
6.1 Delayline Detector - Vacuum Wiring
The delayline detector DLD4040 R2.55 and R3.54 consist of a detection area, defined by the detector
cover, the MCP holders and the detector anode. The detector anode consists of two meander structured
delaylines (named x and y), which are placed above each other (electrically isolated) and are oriented
perpendicular to each other. The one delayline is referred to as the x meander and the other delayline as
the y meander.
gives a schematic orientation of the x and y meander. The meander structured
delayline is close to ground potential (in respect to the high voltage of the MCPs). A pulse coupling layer
is used to isolate the meander from the high voltage of the MCP stack as well as to couple pulses from the
electron cloud into the meander.

Figure 9: Schematic orientation and naming of delaylines and DLD image.
Signal readout is done via two readout lines (named 1 and 2) for each meander-structured delayline.
The naming of the readout lines is put together of the naming of the meander structured delayline x and
y and the naming 1 and 2 of the individual readout lines per delayline (e.g. X2 for the second line of the x
meander).
The 0/0 position of the DLD image (top left corner of displayed image in the GUI software) is marked by a
red dot.
