All the xenon must somehow get to and from the detector through the water tank, as must signal and high voltage cables, various sensors, and we need large pipes to get a really good vacuum for cleaning the detector prior to filling. We use one large pipe for this lifeline of the detector, an aorta of sorts. Here is spokesperson Elena Aprile illustrating the huge scale of the XENON experiment.
In XENON100, we observe individual electrons and describe this signal together with its applications in a dedicated publications:

In order to search for dark matter, it is imperative that background signals in particular from neutrons are well under control. We describe the successful techniques and leading results from our efforts in a dedicated publications:
Dark matter is expected to induce nuclear recoils in our detector. We have demonstrated that we have an excellent matching of our expectation and the measured response of the XENON100 detector to such nuclear recoils, with an agreement at the percent level:
Using data from the year-long search for dark matter with XENON100, we could derive world-leading limits on spin-dependent interactions of dark matter:

In order to operate the XENON100 detector in a stable way over the course of years, we require a thorough control of various operation parameters. The corresponding system is described in a publication:
Our detector is so sensitive that we can detect individual photons and individual electrons. A description of the response of the detector to the latter is published here:
Analyzing terabytes of background and calibration data in the search for just a couple of dark matter-induced events is a difficult process that we published in a dedicated paper:
We have published the results from a year-long search for dark matter. Unfortunately, we could find no evidence for dark matter yet:
We have published a paper that describes the XENON100 detector in quite some detail, together with the corrections that need to be applied to the data we collect with it:
