Close-up photograph of the Microball installed in Gammasphere. The Microball detectors are supported by thin Delrin rings which are held by aluminum legs. The supporting structure allowing 9 degrees of freedom (rotations and translations) is used to align the device to the chamber and the beam axis. The detectors are held by rectangular blocks that hold the two leads of the photodiode. The signal cables are thin shielded coaxial cables (75 Ohm) with Teflon insulation and connect the diodes to their preamplifiers located outside the vacuum. Ring 6 is located at exactly 90^o and it has an opening to allow the target rod to be inserted in position.
