The STIC Photo Gallery

One of the two STIC calorimeters after it has been installed around the beampipe in one of the end-caps of DELPHI. The white cables in the lower right corner are fiberbundles for the Vetocounter. Front-view of a STIC calorimeter. In the center of the calorimeter is the hole for the beampipe. Around the hole is a ring of electronics for the LED system and around the outer edge is a ring of electronics for the Si Strip shower maximum detector.
One of the 16 amplifier cards used to amplify the signals from the Si Strip detectors. These cards sits on a ring-shaped printed circuit board together with two so-called master-cards which are used for the final 8 to 1 multiplexing of the Si strip signals from the amplifier cards before they are sent to the Sirocco Flash ADCs in the countingroom. Close-up of the front showing the details of the LED and Si Strip electronics.
One of the two Silicon Strip detector layers showing the inner ring of Si Strip detectors. A complete layer has also an outer ring. A side-view of STIC showing the kapton cables which takes the Si Strip signals out of the calorimeter and two MX4 fan-in cards used for the first 120 to 1 multiplexing and for charge amplification.
A close-up of the wavelength shifting fibers and the fiberholders which are attached to tetrodes in the finished detector. The inside of one calorimeter module (a calorimeter consists of two such modules). The top half of the picture shows the sandwich structure of the detector and the bottom half shows bundles of wavelength shifting fibers.

The STIC prototype detector which was tested in a testbeam in the West Area before the construction of STIC. A close up of a scintillator layer showing the tower structure. Each calorimeter has 160 projective towers. There are several holes for the fibers in each scintillator tower tile and in addition two holes used to attach the tile with a very high precision to the lead plate.
