Sorry for pure quality of the photo itself (especially horizontal alignment).
VSAT position is difficult to access (more tnan that - the place is open
for service only during long LEP stops).
The camera was inserted inside box with beam-pipe and quadrupole
cooling system to take this close picture.

The stainless steel tube with flange on the in center of the picture is LEP beam-pipe. One aluminum box on one side of this tube is VSAT 1'st module (B2), another one - 2'nd (B1) module. Of course VSAT detector parts is much smaller than these boxes which also holds preamplifiers, temperature probes, support and cooling systems.
